Flatten PDF forms, annotations and page content

This tool rasterizes every PDF page and rebuilds the document from rendered page images. The result preserves the visible appearance while removing selectable text and interactive form behavior.

How to flatten a PDF

Flatten form fields and annotations

Flattening can turn certain annotations, form appearances, or layered elements into a more fixed visual representation. This is useful before printing, archiving, or sharing finalized documents.

When to flatten a PDF

Use it when comments, form fields, stamps, or overlays need to appear as part of the final page rather than remain interactive.

Flattened PDF text is no longer selectable

After flattening, some interactive elements may no longer be editable. Keep an original copy if you may need to change form fields or annotations later.

Flatten PDF vs password protect PDF

Flattening changes how document elements behave; it is not a security feature. Use Protect PDF when you need password protection.

Choose the right flattening resolution

Choose 120 DPI for smaller output, 150 DPI for a balanced result, or 200 DPI for sharper pages. Higher resolution can increase the final PDF size.

Review the final output

Open the flattened PDF and check forms, signatures, stamps, and annotations before relying on it for printing or submission.

Frequently asked questions

How do I flatten a PDF?

Upload the PDF, choose 120, 150 or 200 DPI, select Flatten PDF, and download the rebuilt rasterized PDF.

Will text remain selectable?

No. This flattening method renders each page as an image inside the output PDF.

Why choose a resolution?

Higher DPI produces sharper pages but larger files.

Does flattening remove interactive forms?

Because pages are rendered, interactive form behavior is removed from the flattened output.
