Auto-redaction requires a text-based PDF. For scanned PDFs, first use our OCR tool to create a searchable PDF, then redact it.
PDFTash uses Claude AI — one of the most accurate language models available. It correctly identifies email addresses, phone numbers, and credit card numbers with very high accuracy. Names and addresses can sometimes be missed if they appear in unusual formats.
Free users can redact PDFs up to 10MB with no signup required. Pro users ($2/month) can redact files up to 200MB.
