Why should I redact a PDF before uploading to AI tools?
AI tools like ChatGPT can read everything in your uploaded PDF—text, numbers, and even metadata. Before sharing sensitive documents with AI services, remove personal information, account numbers, signatures, and hidden metadata to keep your data safe.
What information in my PDF can AI tools access?
AI tools can access all visible text, numbers, images, and metadata in your PDF. This includes names, addresses, account numbers, signatures, comments, and hidden document properties like author and creation date. RedactionPDF helps you remove all of this before upload.
Does RedactionPDF send my documents to AI models?
No, your documents are not used to train AI models. RedactionPDF processes files temporarily and automatically deletes them according to the retention policy, keeping your data private.
What types of information should I remove from my PDF?
Remove these before uploading to AI tools: names and signatures, email addresses, phone numbers, physical addresses, account numbers, Aadhaar numbers, financial details, internal project names, confidential notes, and hidden metadata. RedactionPDF auto-detects these patterns to help you.
Does redaction also remove PDF metadata?
Yes, RedactionPDF automatically strips all PDF metadata—including author, creator, timestamps, and custom fields—beyond visible content. Your documents go into AI tools clean, with no traceable metadata left behind.
How long are my files retained on the server?
Original PDFs are deleted after processing. Redacted PDFs remain available for up to 1 hour, giving you time to download them before permanent removal.
Can I redact scanned PDFs before uploading to AI tools?
You can manually redact visible areas on scanned or image-based PDFs. Automatic detection works best with text-based PDFs.
Is RedactionPDF free to use?
Yes, the basic redaction service is free to use. Files are processed temporarily, metadata is cleaned, and auto-detection helps find sensitive patterns before you apply permanent redaction.
