Flatten PDF
Flattening a PDF bakes annotations and optional content layers directly into each page so nothing can be toggled, moved, or hidden afterward. The result is a single-layer document ready for reliable printing or sharing. Note that interactive form field values are not baked into the page — see the on-page note for details.

Frequently Asked Questions
Does flattening preserve values I typed into form fields?
No. The form widgets are removed but their entered text is not rendered onto the page. To truly bake form values in, convert each page to an image with the PDF to Image tool.
Will flattening change how my document looks?
The visual appearance of pages stays the same; only interactive elements like annotations, layers, and form widgets are affected.
Why should I flatten a PDF?
Flattened PDFs render consistently across viewers and printers, prevent further annotation edits, and are often required by submission portals.
Is my file uploaded to a server?
No. All processing happens locally in your browser — your file never leaves your device.
