Flatten PDF form fields
Make interactive form fields and annotations permanent — they become part of the page and can no longer be edited. Text stays searchable and copyable. Everything runs in your browser.

Three steps. Done.
Drop your PDF, click Flatten, and download. No account, no upload, no waiting.
Drop your PDF
Drag and drop or click to choose a PDF with form fields.
Click Flatten
One click merges all form values into the page permanently.
Download
Your flattened PDF is ready — text searchable, file size unchanged.
Keep values, remove interactivity
Flattening is the final step before sending important documents.
Values locked in
Filled-in text, checkboxes, and signatures are baked into the page permanently.
Text stays text
Unlike rasterising, flattening keeps the original text layer — still copyable and searchable.
No more editing
Recipients can read but not modify form data — ideal for contracts and official documents.
Works everywhere
Flattened PDFs open cleanly in any viewer without needing form-field support.
Your file never leaves your browser

Good to know
Flattening is powerful but has some caveats.
Form fields only
This tool flattens AcroForm fields. Freehand annotations (sticky notes, highlights) are preserved but not flattened.
Irreversible
Once flattened, form fields cannot be restored. Keep the original if you may need to re-edit.
Encrypted PDFs
Password-protected PDFs are opened in compatibility mode — unlock first for best results.
Common questions
What does flattening a PDF do?
Flattening merges all interactive form fields (text boxes, checkboxes, radio buttons, signatures) into the static page content. The values are preserved visually but the fields are no longer editable.
Is flattening the same as converting to image?
No. Flattening keeps the original text layer — text remains selectable and searchable. Converting to image (rasterising) replaces everything with pixels and loses text quality.
Can I undo a flatten?
Not from the flattened file. Always keep the original PDF if you may need to re-edit the form. The flattened version is a separate download.
What PDF form types are supported?
iKeepPDF flattens standard AcroForm fields (the most common type, used by Adobe Acrobat, Word PDF export, etc.). XFA forms used in some government PDFs may not flatten correctly.
