Flatten PDF Forms and Annotations

Burn fields, comments, and markups into the page so recipients see a fixed document.

How to flatten a PDF

  1. Open the PDF: Drop a filled form or an annotated file.
  2. Flatten: Run flatten so fields and comments become part of the page stream.
  3. Download the static PDF: Recipients can read the content without editing live form fields.

Why this tool

  • Locks in filled values: Useful after Fill & Sign when you want a non-fillable archive copy.
  • Local only: Flattening happens in WebAssembly on this device.

Frequently asked questions

Is flatten the same as encrypting the file?

No. Flatten makes content static. Use Protect PDF to add a password. Use Redact PDF to remove hidden text.

Can I keep a fillable copy too?

Yes. Export a flattened copy for sending and keep the original fillable file locally.
