Flatten PDF
Lock in filled forms and comments before sending a document. Flattening draws form fields and annotations into the page content so they look the same but can no longer be edited.

How to flatten a PDF
- Select the PDF.
- Choose what to flatten: form fields, supported annotations, or all supported elements.
- Review what will be flattened and what can't be.
- Press Flatten PDF and download the result.
Key features
- Uses each field's and annotation's own appearance, so the result looks the same.
- Nothing is converted to an image; text stays text.
- Links are kept.
Supported files and limits
- Flattening removes interactivity permanently: fields can't be filled and comments can't be edited afterwards. Keep the original if you may need them.
- Some annotations without a stored appearance can't be flattened and are reported.
- Protected PDFs are refused.
How your files are handled
Flatten PDF runs in your browser: your file is read and processed on your device and the result is created there, so documents aren't uploaded to a server. The site only counts anonymous page views, without cookies. How it works · Privacy
