How to Add Page Numbers, Watermarks, and Passwords to PDFs — No Software Needed

Quick scenario: your boss emails you a 47-page PDF and says "add page numbers, slap our logo as a watermark, and password-protect it before sending to the client."

You could install Adobe Acrobat ($20/month). You could try one of those "free" online tools that upload your confidential files to who-knows-where. Or you could open three browser tabs and be done in 90 seconds.

Step 1: Add page numbers

Open the Page Numbers tool. Drop your PDF. Pick a position (bottom center, top right, whatever). Click generate. Done.

Step 2: Add a watermark

Open the Watermark tool. Upload the numbered PDF. Type your company name or upload a logo. Adjust opacity and position. Generate.

Step 3: Password-protect it

Open the Protect tool. Upload the watermarked PDF. Set a password. Download the encrypted file.

Total time: about 90 seconds. Total cost: $0. Files uploaded to a server: zero — everything runs in your browser.

Why not just use Adobe?

Adobe Acrobat Pro costs $19.99/month. For most people, you need page numbers once a quarter. You need to compress a PDF before emailing it. You need to merge two contracts.

Compare the best free PDF editors in 2026 — you might be surprised how much you can do without paying a subscription.

Other things you can do

Parchment has 15 PDF tools total — merge, split, compress, convert to images, extract pages, unlock, reorder, and more. All free, all client-side, all open source.
