Über dieses Tool

Flatten PDF merges form fields and annotations into the page itself, producing a clean, non-editable document. Useful for locking in answers, markups, and approvals before final distribution.

Batch flatten multiple files so delivery copies carry no editable or movable layers.

Everything runs locally in your browser, keeping your PDFs private and the tool free.

Häufig gestellte Fragen

Why flatten a PDF?

Flattening removes editable elements so content and signatures cannot be changed or moved.

Are flattened files editable?

No - flattened content is merged into the page and is no longer an active field.

Is my PDF uploaded?

No - flattening runs entirely in your browser.
