About Flatten PDF
What Flattening Does
Flattening a PDF converts interactive form fields and annotations into static page content. Text fields, checkboxes, dropdowns, radio buttons, and signature fields all become part of the page image. The values stay visible, but nobody can change them.
OxygenPDF detects how many form fields your PDF contains, shows you the count, and flattens everything in one click. The result is a standard PDF that looks the same as the original but with no editable fields. All processing happens in your browser.
When You Need to Flatten a PDF
Interactive fields are great during data entry. Once a form is complete, flattening locks it down.
Lock Completed Forms
After a form is filled out and signed, flatten it so recipients can’t alter the entries. The content becomes permanent.
Fix Printing Issues
Some printers and print services misrender form fields. Flattening eliminates the interactive layer, so what you see on screen is what prints.
Cross-Viewer Compatibility
Form fields render differently in different PDF viewers. Flattening bakes the content into the page so it looks identical everywhere.
Reduce File Complexity
Interactive elements add overhead to a PDF. Flattening strips that layer, sometimes reducing file size and always simplifying the document structure.
How It Compares
Flattening is a common PDF operation, but not every tool makes it accessible without a paid plan.

Your Forms Stay on Your Device
Filled forms contain personal data, signatures, financial details, and medical information. Uploading them to flatten is an unnecessary risk.
OxygenPDF flattens your PDF entirely in the browser. The file stays local. The flattened output downloads to your machine. Nothing gets transmitted.
