Whenever I edit my PDFs they triple in size!

21 Jun 2007 | | No Comment

It’s an issue that causes heart palpation’s for new users of PDFs every day. You spend two hours primping and pruning your PDF document — editing a word here, adding a comment there — and then save your document and try to attach it to an email message only to discover that it’s file size has tripled and your email client won’t accept it. What the hell is this crap you scream!?

In a fit you shoot off an email to some forum in cyberspace, begging for help and swearing that you’ll never touch another bloody PDF if there isn’t a way to fix this problem. Within 5 minutes a helpful forum member posts a three worded response… “Use Save As“. You do as he says and hey presto, your PDF is back to it’s original size. A simple fix for a big problem. You are happy again.

But why did the file size increase in the first place?

The increase in the file size is the result of the incremental saves that are made when you make changes to a PDF document. When you use Save As the unused incrementally saved data is removed and the file size is returned to normal [or there abouts]. Appligent Labs have posted an article on this issue and they give an explanation for why these incremental saves are required. Check it out here.
