One PDF To Go, Please: A PDF In The Palm Of Your Hand

The portable document format does live up to the word “portable.” Whether you’re a busy entrepreneur, a workaholic or a web surfer, location doesn’t seem to really matter anymore. Everything is going mobile.

And you’re probably seeing a lot of technology moving from the desktop computer to the handheld device, which adds yet another category of decisions about your working habits that change with along with the trends.

So if you’re interested in joining the iddy-biddy-sized mobile world with your PDF work, here’s a brief background on some details surrounding PDFs on mobile devices .

Creating A PDF Optimized For Handheld Mobile Devices

First of all, regardless of what PDF creation software you have, you can create PDF files specifically optimized for mobile browsers by paying attention to a few details about your PDF.

1) File size. Use the Save As command to save the PDF. This will re-write the entire file and not just append the changes made to it, making it a more compact size that won’t ruin the integrity of the PDF.

2) Images. For images, use the best compression settings to ensure that you don’t include unnecessary pixel data. Using a lossy compression (JPEG and ZIP) or downsampling will help to decrease this.

3) Fonts. Don’t embed many, unnecessary fonts as embedding fonts also increases file size. Mobile devices importing the PDF may already have the fonts needed to render the text.

4) Tags. One of the key differences between desktop PDFs and mobile PDFs is file structure. Just as structure is important for reflowing the text to fit screen readers, it serves the same purpose for mobile browsers. Ensure that only the necessary tags for smooth textual reflow are included with the PDFfile.

Software For PDF Mobility

Palm OS, Symbian OS, Black Berries, and MS Pocket PCs are the most popularly used mobile OSs. The OS’s compatibility will play a factor in your mobile PDF research as some PDF software for handheld devices won’t support all platforms.

But for starters, there’s Adobe Reader LE. The software is supported by Symbian OS, Windows Mobile (Pocket PC 2.0), and Palm OS. Reader LE comes pre-installed on some mobile devices and supports scrolling, zooming and decryption for viewing your PDFs. As well, the software can support text search, bookmarks, and links within the document. In addition, Adobe has a user discussion forum for users with any tech support topics or tips regarding the software.

Features for different mobile devices vary. For instance, for Symbian OS devices, such as Nokia Smartphones, you can view a PDF as either a tagged PDF or in its original formatting. With Pocket PCs, you can directly print wirelessly from your handheld device to a remote printer. Adobe Reader LE on Palm OS devices allows you to view and transfer your Digital Editions e-books to your device. And another thing to note, there are a different variety of language options for you to choose from with each individual download.

Other mobile software supporting PDF viewing includes Dochawk Platinum 2.0, Repligo Professional 2.0, mBrainsoftware, DataViz’s Documents To Go v.9.0. Add them to the research list as it might come in handy as well.

Why Would You Need Mobile PDFs?

Now many users already complain about the usability of the PDF because of the long periods of time that can be spent in front of a screen. And handheld mobile devices have viewing and interactivity problems of their own (how small can a keyboard get?).

So why would you need PDFs on the go? One major reason is that, light and compact, handset devices are ultimately a matter of convenience. And when working away from your desktop, you need to have access to all the important documents you need—even PDF documents.

Checking emails on the way to work has perhaps become a daily routine for some. And undoubtedly, opening email attachments that are in the PDF format may be part of that. Or, for a PDF workflow that is almost essential to niche industries, such as publishing, for instance, emergencies that need attention don’t anticipate (or care) where you’ll be when they happen. And unfortunately, for others, going on vacation or getting ill doesn’t mean they stop working altogether– not with a PDA in hand and thumbs poised in the air.

Going portable with portable documents. . . . It does add a nice spin to the name, Portable Document Format!

The ABCs of the PDF: G-I

Veering away from XPS this week, I’ve got the next posting in the ABCs series for you. It’s been a while, but here it is. This week, it’s about the history, the mechanics and the product. A little vague? What does this have to do with the PDF?, you ask. Read on.


From creation to manipulation and accessibility to view-ability, the GUI’s function is crucial to working with PDFs. Yet have you ever wondered about the history behind the interface you use? The first rough idea of a GUI was conceived of by American engineer, Vannevar Bush (1890-1974) in the early 1930s. In his essay “As We May Think,” published in 1945, Bush describes a device he called the “Memex” that would transform physical gestures into technical commands. A user could call up and display multiple “book” files on a desktop screen and jump through pages of content with the movement of one’s hand. Yet, it was only theorized about until Douglas Engelbart (1925-2013),  inspired by Bush’s idea, decided to develop and implement the idea into a prototype. In 1968, the first working GUI was demonstrated.

The first marketable GUI using computer was invented by Xerox PARC in 1973 with the Xerox Alto computer. It was further enhanced by Apple’s revolutionary Apple Lisa PC ten years later in 1983. And by the 1990’s, the GUI of Microsoft’s Windows OS improved the functioning of the GUI into the one you know today. Of course, the interface has also been developed and used by a number of individual computer companies over the years, and it has come a long way in terms of looks and usage.

The goal for the GUI nowadays is to provide the most functionality within the least amount of space. And Adobe Reader 8 is just one example in its simplicity. Perhaps in the future our PDF viewers will do away with the GUI altogether, and use virtual reality as a way of “handling” PDF documents!

Hash Function

So far, we’ve made it so that electronic docs would be an easy way of storing and recording data. In addition, it prevents data from being physically lost or stolen– invisible and intangible until opened and printed. Yet, that also means that security has transferred from playing a physical role to a digital one. And just as you need a sense of security when physically locking doors, you also need it when securing electronic documents.

You already know that information security is important to the PDF and can be done with the click of a mouse. Yet, one of the things behind that simple move is something called a Hash function . Hash functions or algorithms play a role in creating a digital signature which you’ve undoubtedly used in the past to secure your PDFs. It is that digital signature which is made up of a hash and encryption key.

A textual message or document is made into a smaller data version of itself through a “hashing” process. When this happens, the content of the message is encoded, using a hash function. The hashed version of the message is called a message digest, which is, in turn, encrypted with the author’s private key. The resulting encryption of the message digest is the digital signature that you attach to the original PDF Document. All of this is done behind that one deceptive click.

And although the term “hash” may seem a funny word to refer to a security/encryption element, according to definition sources, it caught on in the 1960’s because it described the way in which hashing algorithms work—they “chop and mix” up the data being secured.


The ever changing nature of the electronic world is not a new concept. Software and gadgets continually evolve within the fast paced environment of technological innovation. And Investintech has also been caught up in that forward momentum with the recent release of Sonic PDF Creator v.2.0. And, with its more-advanced-than-v.1.2 features (support for more formats, document toolkits and formatting capabilities), you can now create better PDF documents than you did before.

Of course, we’ll aim to surpass this 2.0 version in the future as well and continue to push the PDF creation envelope. It’s just a matter of checking in frequently to see what new creation features we’ll have in store!

‘Til next time. Stay tuned!

The ABCs of the PDF: D to F

The holidays are over for this year and it’s time to get back to work—and back to learning. Here’s the second posting on the ABCs of the PDF and, as promised, a few tidbits behind the day to day elements you use in your PDF work.


The most important thing about a PDF is the data— its printability, its transmission and its integrity. Of course, this last point is the driving force behind the inability to edit PDF content, a quality with which the PDF world is familiar.

There have been notable rants and raves about this and, consequently, about the “usability” of the PDF format, citing issues such as document size and on-screen behaviour as annoyances. And yet, there are strong arguments defending the PDF and the working needs it fulfills with its “set-in-stone” data.

What do we make of this PDF usage debate? What’s the bottom line for PDF users, makers and shakers?

Fantasy: digital documents that aren’t easily manipulated by malicious users.

Reality: file integrity and data extraction go hand-in-hand with the PDF format. The only way to change or work with the data is to extract (aka “convert”) the content.

Conclusion: when working with a PDF, work with conversion in mind —which conversion software is practical for daily use, which format conversions you need, what kinds of PDFs you’re working with (scanned or native), what security features restrict the data you need, etc.


And speaking of security, you’ll more than likely encrypt the PDF documents you create yourself. So, here are a few knick-knacks surrounding the encryption you’ll use:

• You may see the word “bit-encryption” when creating a PDF. Bit-encryption, which secure your documents, is based on the use of binary digits

• The higher the bit-number, the more secure your files are because of the increased probability of possible decryption keys. A 128-bit encryption, for instance, has a key length of 128 bits long, meaning that there 2128 possible keys

• Sonic PDF Creator v.1.2 includes 40- and 128-bit encryption

• The DES (Data Encryption Standard) was based on 58-bit encryption and adopted by US Federal government in the 1970’s. The current AES (Advanced Encryption Standard, 2000) is based on the RijnDael algorithm which makes use of128- to 256 -bit keys. It was adopted after winning a 3-year competition against other algorithms

• The concept of the computer, in fact, was based upon “cracking codes.” It was developed during WWII while trying to decode encrypted messages through the use of an “Enigma” machine


As a PDF user, you know that part of maintaining the document’s appearance is retaining the textual font within the PDF. Yet, there is more to fonts than just a pretty face.

• There are about 20 components in the anatomy of a letter that define one typeface from another

• There are 3 different types of hyphen/dashes and, of course, vary in usage— and in look, from typeface to typeface (Three? Yes, three. Who would’ve thought?)

• Which fonts are best used for on-screen (PDF) presentation?

• The fonts used in a document affect the way you read the textual information. Serif fonts help to guide a reader’s eye along the lines in large blocks of text. Thus, Times New Roman, for instance, is generally used for printed text. Sans-serif fonts are used ideally for on-screen text because it presents a legible rendition on-screen

• Do you know the history behind the letters and fonts you use in your PDFs?

Hopefully, next time you read or create a PDF, you’ll look and think differently about the extraction, the encryption and the fonts you use on a daily basis. And, who knows, with a little tinkering, you just might create that ultimate PDF!

The ABC’s of the PDF: A-C

I must confess that I’m by no means an expert on the ins and outs of the PDF. Having said that, I must also confess that, since beginning this blog and writing articles for the company website, I’ve learned A LOT. And with that in mind, I thought it would be fun to share in the learning.

I’ve been wanting to do a series of postings for a while now and thought, what better topic to do it on than the ABC’s of the PDF? I’ll be researching tidbits surrounding the PDF, getting you to know the format in a different way. I’ll also include links to articles, both new and old, as well as to relevant sites if you’re interested in reading more about a topic so that I don’t leave you in the lurch (you can only cover so much in a blog entry!). So, if you’re ready for it, we’ll start (where else?) at the beginning.

Adobe System, Inc.

Proprietor of the PDF format, Adobe System, Inc. was founded in 1982 by John Warnock and Charles Geschke (current Chairmen of the Board for Adobe). This company has been ranked and recognized in top business magazines, such as Fortune and BusinessWeek and currently consists of approximately 5,879 employees worldwide. In addition, the PDF actually makes up almost 10% of web content on the internet today. Did you know that the company, itself, was named after a creek in Los Altos, California located behind Warnock’s home? There’s even an Adobe Day on December 2, which was established in San Jose in honour of the company’s 20th anniversary in 2002. Does the company get the day off for that one?

Bruce Chizen

What is the history behind this PDF household name? In a 2001 interview with PlanetPDF, Chizen stated: “ ‘In five years I hope people can look back and base my legacy on what we were able to do with Acrobat.’ ” Well, five years later, Acrobat is more capable than ever and his legacy is safe. Since March of 2001, Bruce Chizen has been the president and CEO of Adobe Systems Inc., coming into his new role after having been with the company since 1994. For those 6 years in between, he’s held top head positions over the professional graphics division and Adobe’s consumer division. In his pre-Adobe days during the eighties, Chizen worked for Claris Corporation, Mattel Electronics and Microsoft where he gained the background and experience that would lead him to becoming Adobe’s head honcho.

Camelot Project

This project was the conception of the PDF, itself, as we know it today. As part of PDF history , the original document was written by John Warnock, as CEO of Adobe in the spring of 1991. Camelot was essentially geared towards making the fundamental elements of PostScript and PostScript Printers more efficient both electronically and economically. In the original document, Warnock envisions the technology, software, and implications of what, with innovation, the application of PostScript language could achieve: documents that were universally viewable. “This capability,” Warnock states,“would truly change the way information is managed. Large centrally maintained databases of documents could be accessed remotely and selectively printed remotely. This would save millions of dollars in document inventory costs.” The culminating result: PDF. The original name, ‘Camelot’, however, was later renamed to ‘Carousel’, which is said to be the reason why the PDF file type on Macintosh was ‘CARO’.

Okay, so that’s it for this series posting—don’t want to give away too much all at once now. There’s still more to come. Stay tuned for the next posting in the series where I’ll look into the nuts and bolts behind the PDF features which you use on a day to day basis. Releases New Product Versions

Good news everyone!

We’ve just released the newest version of our flagship product, Able2Extract, this week. It’s now at version 4.0, which means more advanced conversions for extracting PDF graphics into different formats.

And in addition to that update, we’ve also improved our Able2Doc products as well, with better PDF to Word conversion output and an updated interface.

Of course, if you have previous versions of our software, we’ve got upgrades posted up for you so you don’t miss out on the latest features.

And so, in honour of taking one gigantic step forward with the new release, I thought it would be a good time to take a small step back. Releasing a new product version is always a perfect time to reminisce about the “good ol’ days”—thinking about where you’ve been and what you’ve done. And, in 6 years, after hard work (read: blood, sweat and tears) we’ve come a long way!

A Brief Trip Down Memory Lane

We also have our own history of fun facts to know and tell that date back to our foundation in 2000. In the early days, when trying to build the name and the product line, Investintech worked out of the company president’s apartment for a time (that’s right, “home base” was actually “home”). The staff was numbered at only 3 at the time: the president, executive vice president and lead developer, which meant honing down those much needed multi-tasking abilities until workloads demanded a staff. It consists of 9 members today.

The name “,”  itself, was coined because the site was initially supposed to be a financial information website focused on small cap technology companies. In the end, we found a nice niche in the PDF world, expanding one idea into another and eventually into one that combined specific working needs and practical software demands.

Our first product, Able2Extract 1.0, in fact, began as a simple PDF to Excel converter, which worked well, but not well enough to be put out on the market. After innovation, expansion and development, the products branched out into ones with more advanced capabilities—Able2Doc, Sonic, OCR technology, better GUIs, SDKs, server side software, conversions to HTML, PowerPoint, Word, and (better conversions to) Excel. Thus, this new version adds another big milestone to the list with a foothold in the graphic conversion arena.

Now, in a nice and cozy (and just as home-y) office here in downtown Toronto, Investintech has grown into the company you see on the screen before you.

There’ve been many challenges and successes along the way, and these new product versions are only one of them. And undoubtedly, there’ll be more to come.
