I'm looking to merge a couple .pdf files for a one-off and don't want to install anything on my PC.
Anyone know of any web apps which will let me merge .pdf files?
You can use Google Docs to upload, modify and combine PDFs, then output it as a new PDF. Might cause some formatting issues if the PDF contents are really funky, but it's free and easy and you probably already have a Google account.
While not a webapp, you may be interested in PDFTK Builder Portable - a version of PDFTK Builder that can be run without installation on Windows.
Have a look at PDF Mergy. Allows to merge pdf files with a drag and drop interface. Requires a recent HTML5-capable web browser.
I know this comes a bit late, but maybe it helps anybody who happens to stumble across this.
PDF Rider is an open source project on Codeplex. This utility provides a GUI for the command-line program Pdftk.
PDFSAM (PDF Split and Merge) is another free, open source utility to split and merge pdf files.
I've tried both in the past & found PDF Rider to be faster than PDFSAM.
