Redaction that actually removes.

A black box on a screen is not redaction. PDFluent rewrites the PDF so the underlying text is permanently gone — not hidden behind a shape someone can drag away. Hidden metadata gets stripped in the same pass.

  • Text content actually erased — not overlaid.
  • Metadata, embedded fonts and JS stripped in one click.
  • Preview shows exactly what stays in the saved file.

of severe
security bugs

~70% of severe software security bugs are memory-safety flaws — independently reported by Microsoft and Google. PDFluent is built in Rust, which makes that entire class impossible: gone by design, not patched after the fact.
