Short answer
Before you paste or upload a PDF into an AI chat, strip personal data locally. Use Sanitize for AI below to extract and review text, then Auto-redact or Redact on the original if you must share a cleaned file. Nothing is uploaded to mypdf.

How it works
- 1
Open the PDF in Sanitize for AI below and review the extracted text.
- 2
Note emails, phones, addresses, IDs, and account numbers you must not send to an AI.
- 3
On the original PDF, run Auto-redact PII or Manual Redact for those regions.
- 4
Optional: Remove metadata / Deep Clean before any further sharing.
- 5
Paste only a minimal sanitized excerpt into the AI product.
Who needs this
- Professionals drafting with ChatGPT on client or employee documents
- Students using AI on transcripts, resumes, or application PDFs
- Anyone who almost uploaded a full PDF to an AI tool
Files never leave your device
Sanitize and redact tools run in your browser. Files never leave your device on mypdf. AI providers are separate — do not assume their chats are private.
Limits worth knowing
- Sanitize extracts text — it does not auto-delete every PII type from the PDF bytes.
- Use Redact for permanent removal on the file itself.
- Scans need OCR before text PII is visible.
