About This Tool

Flatten PDF documents with our free online PDF flattening tool. Convert interactive form fields, annotations, and layers into static content, creating permanent non-editable files compatible with Adobe Acrobat Reader and all PDF viewers.

Remove fillable form fields, comment layers, and interactive elements while preserving their visual appearance. All form data becomes permanently embedded in the document. Essential for finalizing completed forms, archiving documents, or preventing further edits.

All PDF flattening happens locally in your web browser. Your documents never upload to external servers, ensuring privacy for completed contracts, signed forms, and finalized business documents. No registration required.

Perfect for archiving completed forms, creating non-editable versions of contracts, preparing documents for court filing, or reducing file complexity. Works with fillable PDFs from Adobe Acrobat Pro, Adobe LiveCycle, and other form-creation tools. Annotations from Adobe Reader and other markup tools are also flattened.
