Flatten PDF

About this tool

Flatten PDF merges all interactive form fields and annotations into the static page content of your PDF. Once flattened, fields can no longer be edited — the filled values become permanent text on the page. This is useful before sharing or archiving completed forms.

  Field values, checkboxes, and signatures remain visually intact.

Frequently asked questions

What does flattening do exactly?

Flattening converts all interactive AcroForm fields and their current values into permanent page content. After flattening, the form is no longer fillable — it looks identical but behaves like a regular PDF page.

Will annotations also be flattened?

Yes. Annotations such as comments and highlights are also merged into the page content during flattening.

Can I un-flatten a PDF?

No. Flattening is a one-way operation. Once flattened, the interactive fields cannot be recovered. Keep a copy of the original if needed.

Are my files stored on your servers?

Files are automatically deleted after the operation completes. We do not retain your documents.
