Flatten a PDF form

Convert form fields into static content (flatten), for sharing/archiving. Everything is done locally in your browser.

Import a PDF

Choose a PDF containing form fields (filled or not).

No upload: your files remain on your device.

Archiving and ComplianceKeep a "frozen" PDF where fields can no longer be modified after validation.
Sending to a Third PartyShare a completed form without granting access to the fields or form scripts.
Preparation for PrintingAvoid rendering surprises related to fields (checkboxes, text fields) depending on the viewer.
Before SignatureStabilize the appearance of a form before a signature step (according to your process).

A flattened PDF: the values of the fields are rendered as static content on the page.

A summary (JSON/report) of the processed fields: names, types, values, pages, and status (flatten ok/partial).

Once flattened, you will no longer be able to modify the fields (unless starting from the source PDF).
Depending on the PDF, some field appearances may be incomplete if the appearance stream is absent or non-standard.
Flattening may invalidate an existing signature: do it before the signature, not after (unless controlled cases).

Will my values remain visible?

Yes: the goal of flattening is precisely to make the value visible as static content.

Are the fields removed?

They are no longer interactive. Depending on the implementation, they may be removed or rendered inactive after rendering.

Can I flatten only certain pages?

If the tool offers range options, yes. Otherwise, it flattens all fields in the document.

Before flattening, export "PDF Form Fields → JSON": you will have a structured backup of fields/values in case you need to reconstruct a form.
