About Flatten PDF

This tool runs your PDF through Ghostscript's rendering and re-distilling pipeline, which typically bakes visible annotations and filled-in AcroForm field values into the static page content along the way — the practical effect most people want when they say "flatten": a document that looks the same and behaves the same in every viewer, with the original interactive layer no longer editable through normal form-filling. This is the reliable case: standard AcroForm fields with visible values on the page.

It's worth knowing the limits before relying on it for something important: XFA-based forms (a different, less common form technology than standard AcroForms) are not reliably handled by this pipeline, and this tool is a general-purpose flattening pass rather than a specialized forms-compliance product. For routine "make this filled-in form uneditable and consistent everywhere" needs it works well; for complex enterprise XFA forms, test the output carefully before relying on it.

Key Features

• Bakes visible AcroForm field values and most annotation appearances into the static page content
• Output renders identically across all PDF viewers, with no interactive form layer remaining
• Runs through Ghostscript's standard PDF re-distilling pipeline — no specialized per-field logic
• Best suited to standard AcroForm-based documents; XFA forms are not reliably supported
• Original page dimensions and visual content preserved
