Finalize PDF

Flatten PDF Free

Use Flatten PDF when a document is finished and should behave more like a final copy: completed forms, marked-up files, signed pages, review packets, or PDFs with comments and links.

Choose the mode that matches the goal: flatten real form fields, remove links and annotation layers, or create a visual fixed copy when appearance matters most.

What this tool helps with

  • Flatten fillable form fields where supported
  • Create a visual fixed-copy PDF when needed
  • Explain selectable text and link tradeoffs
  • Download a new flattened PDF

Supported formats

  • Input: PDF files supported by the browser PDF workflow.
  • Output: a new flattened or cleaned PDF copy.
  • The original editable PDF should be kept if you may need to change fields or annotations later.

Best for

  • Finalizing completed forms
  • Making visible annotations less editable
  • Removing clickable links before sharing
  • Creating stable copies for printing or archiving

Limits to know

  • Flattening is usually not reversible, so keep the original file.
  • Visual fixed-copy mode can remove selectable text, links, fields, and accessibility structure.
  • Flattening is not a substitute for proper redaction of sensitive visible content.

  1. Open Flatten PDF.
  2. Add the PDF you want to finalize.

Common questions

Why flatten a PDF?

Flattening helps turn fields, annotations, signatures, or visual edits into a more stable final page appearance.

Can I undo flattening later?

Usually no. Keep the original editable PDF if you may need to change fields or comments later.

Which flatten mode should I choose?

Use form-field mode for filled forms, clean mode for links and annotation layers, and visual mode when fixed appearance matters more than selectable text.
