Converts interactive form fields and annotations into static page content so they can no longer be edited.

Flatten PDF converts interactive form fields and annotations into static page content so they can no longer be edited or filled. This locks in form data, prevents further edits, and ensures the document renders identically in all viewers. Flattening runs entirely in your browser via qpdf-wasm — your file never leaves your device.

FAQ

자주 묻는 질문

Is my file uploaded anywhere?

No. Flattening happens entirely in your browser using a Web Worker and qpdf-wasm. Your file never leaves your device.

What does flattening do?

Flattening converts interactive form fields and annotations into static page content. The visual appearance is preserved, but the fields can no longer be edited or filled. This is useful for locking in form data before sharing.

Can I undo flattening?

No. Flattening is irreversible — once form fields are baked into the page content, they cannot be made interactive again. Keep a copy of the original if you may need to edit the form later.

Will the flattened PDF look the same?

The visual appearance is preserved. Form field values and annotations render the same way — they are just no longer interactive. In rare cases, complex annotations may render slightly differently.
