Latest PDF Standards

Karl De Abrew

Years ago (and years!) when we used to talk about PDF as being the most prominent document format, we'd always have to add a quick, under-the-breath, "de-facto standard". But when it came to being 100 percent assured that it would be around in years to come, it's always been a case of biting our collective lips and hoping for the best. What we would do if Adobe pulled the plug? Over the past two years, though, it's been nothing but standards, standards, standards when it comes to PDF. In fact, there are so many that it's easy to lose track. In this feature article, Planet PDF Editor Karl De Abrew helps to de-mystify the ever-increasing range of PDF-based standards.

Sophie Knowles

Continuous upheaval is what makes watching the technology industry so exciting. David vs. Goliath battles are waged every day, with startups often winning against much larger businesses. For years and years, many have predicted the decline of the PDF given its age and perceived disadvantages. Today, with the PDF losing ground in emerging areas like mobile and eBooks, the calls for its ultimate demise are growing louder.

OPINION: PDF Continues its March Toward Ubiquity

Dan Shea

About 20 years on, it looks like PDF's inexorable march into dominance continues. The latest development is the US IRS's decision to support PDF-based digital signatures on two key forms (8878 and 8879). The spec might say that "No specific technology is required", but we all know that really means PDF. On a site called "Planet PDF" though, we would say that!

Rowan Hanna

For people who don't spend their time looking at PDF files in text editors*, PDF security is a sometimes misunderstood beast.

PDF Security: A Brief What, Why and How

Jeremy Koadlow

Information that we have stored on our computers can be of a very sensitive nature, things we want private for business or personal reasons. There are also a number of ways that old, and new programs, formats and systems can be hacked. Flaws can be exploited and work-arounds can be made. There are always things that can be done to mitigate these risks.
