A practical online PDF editor

OneFileKit Edit PDF renders your uploaded PDF and lets you place text, images, shapes, signatures, stamps, links, comments, whiteout, and redaction marks on top of real pages.

PDF text is often stored as positioned drawing operations, not editable paragraphs. When direct native text editing is unreliable, the editor uses overlay text so you can still make changes safely. Scanned PDFs can use OCR when available.

Redaction permanently removes marked content on export where supported. Whiteout only covers content visually and is not secure.

Security & privacy

  • Uploads are validated by extension, MIME type, and PDF structure.
  • Password-protected PDFs require unlock for the current job only.
  • Original uploads are never overwritten; exports create a new file.
  • Downloads require a secret token bound to your job.
  • Temporary files and drafts expire after a configurable retention period.
