Make Filled Forms Final

When you fill in a PDF form, the values sit in editable fields that the next person can change or wipe. Flattening merges those values into the page itself, so a signed timesheet, an application or an invoice arrives fixed and tamper-resistant — and it also prevents form fields from rendering differently across viewers.

The tool flattens the document's interactive form fields while keeping everything readable. If the file has no form, it is simply re-saved.

Flattened in Your Browser

Flattening is done with pdf-lib on your device. Nothing is uploaded.

Flatten PDF — Frequently Asked Questions

What does flattening do?

It merges interactive form fields into the page so the values can no longer be edited.

Will it change how the page looks?

No — the visible content stays the same; it just becomes non-editable.

Is my file uploaded?

No — it is flattened entirely in your browser.
