Flatten PDF Form
Convert a filled-in PDF form into static, un-editable text — fields become part of the page so the values can't be changed.

How does the Flatten PDF Form work?
When you fill in a PDF form, the values typically remain editable — anyone with a PDF reader can change them. Flattening converts the filled-in fields into static text drawn directly on the page, locking the values in. This is the right step before submitting a finished form by email or before archiving a signed contract. The flattened PDF looks identical to the editable original but no longer has interactive fields. Conversion runs in your browser; nothing is uploaded.
