CrabPDF tools
Free local PDF editing
CrabPDF is a free in-browser PDF editor focused on text editing. It can edit existing PDF text, run OCR on scanned documents, review low-confidence OCR words, find and replace detected text, split badly detected text fragments, and export flattened redacted PDFs.
Private by design
CrabPDF runs locally in the browser. The editing flow does not require uploading your PDF to a backend server. This makes it useful for quick corrections, private documents, OCR fixes, and local redaction experiments.
