How to Flatten PDF Form Fields

After you fill in a PDF form, the answers are still editable fields. Flattening writes them onto the page as ordinary content, so the form looks the same everywhere and the values can no longer be changed in the fields. Comments and other annotations are not changed.

    Choose Your PDF

    Pick a PDF that has fillable form fields.

  2. 02

    Flatten the Form

    The tool finds the form fields and flattens them all.

  3. 03

    Download the Flattened PDF

    Download the PDF and keep the fillable original if you may need to change an answer later.

Frequently Asked Questions

Answers about this tool.

Why should I flatten a PDF?

So the answers you filled in cannot be changed by retyping a field, and the form looks the same in every PDF reader. It is not tamper-proof: someone with a PDF editor can still edit the page itself.
