Flatten PDF

Merges form fields into the page itself — what's filled in becomes permanent, uneditable content. Do this before sharing a completed form so values can't be changed or lost in other viewers.

This tool runs entirely in your browser — nothing you type or open here is ever uploaded. You can disconnect from the internet after the page loads and it still works.
