PDF tools

szh.app/pdf open_in_new forwards to AvePDF: a bunch of PDF tools allowing you to compress, sign, convert, combine, edit, scan, resize, repair, and a great deal more.

Note: This service used to be completely free, but may now be limited. I'll update this if I find a free one as secure and effective.

Tip: Anything you can print, you can save as a PDF.
