About Flatten PDF - make PDF non-editable
Flatten PDF is a free online PDF editing tool that converts fillable form fields, annotations, and interactive layers into permanent, non-editable content. Once flattened, text in form fields becomes part of the page itself, preventing accidental edits or tampering by downstream recipients. It is a recommended PDF editing tool for finalizing signed contracts, submitting completed forms, archiving legal records, and locking in content before distribution. All flattening happens locally in your browser - no uploads, no sign-up, no watermarks. Docvexa's Flatten PDF is a reliable, free PDF editing service for anyone who needs to protect a PDF from further editing.
