Good uses

  • Create a review copy after filling standard AcroForm fields.
  • Reduce accidental field editing before a non-interactive handoff.

Bad inputs

  • XFA forms or documents that still need field editing.
  • Expecting a legal, archival, accessibility, or signature-compliance guarantee.

Output checklist

  • Confirm every filled value remains visible after flattening.
  • Test checkboxes, radio buttons, calculations, and signatures in the output.

Failure modes

  • Only supported AcroForm fields can be flattened.
  • Flattening can discard interactivity and does not certify the document.

Runtime limits

  • Runs locally in the browser without uploading the PDF.
  • Password-protected and malformed PDFs are rejected.
  • Large or complex PDFs can exceed browser memory limits.
  • Creates a non-interactive copy from supported existing form fields.
