15 Free PDF Tools You Didn't Know You Needed (But Use Weekly)

The PDF Problem Everyone Has

You receive a 47-page contract but only need pages 8-15. You need to merge your proposal with an appendix into one file. Your vendor sends a 23MB invoice that won't attach to your email. You have a Word doc that needs to be a PDF for signatures.

Every time, you Google "merge PDF free" or "compress PDF online" and land on some random tool that:

• Puts watermarks on your output
• Limits you to 2 files per day
• Uploads your confidential documents to servers you know nothing about
• Requires you to create an account for basic operations

There's a better way.
