Is uploading PDFs to ChatGPT private?

ChatGPT and similar products process content on their servers. Use local sanitize and redact first if the file is sensitive.

Does this page upload my PDF?

No. Sanitize for AI runs in your browser.

What should I check before uploading to AI?

PII, hidden text, metadata, and whether you need the whole file or just a short excerpt.

Should I upload the whole PDF or paste text?

Prefer a short, sanitized excerpt when possible. Full-file uploads to AI products leave more data on their side.

Short answer

Treat ChatGPT (and other AI chat) uploads like sending a document to a third party. Drop your PDF below to extract text locally, review for emails, phones, and IDs, then decide what — if anything — to paste. Pair with the privacy checker for hidden text and metadata. Files never leave your device on mypdf.

Safe for AI — quick checklist

Sanitize here to extract visible text only (local — not sent to ChatGPT/Claude/Gemini).
Scan for PII with the privacy scanner or privacy checker.
Redact anything the model should not see, then paste a short excerpt — not the whole file.

How it works

1
Drop the PDF into Sanitize for AI below — processing stays in your browser.
2
Review the extracted text for names, emails, phones, IDs, and secrets you would not paste into a chat.
3
Redact or Deep Clean first if the file still contains sensitive layers.
4
Copy only the minimum excerpt you need into ChatGPT (or skip upload entirely).
5
Re-check with the privacy checker before sharing the original PDF elsewhere.

Who needs this

Anyone pasting contracts, resumes, or medical notes into ChatGPT / Claude / Gemini
Students uploading lecture PDFs that may contain personal details
Teams drafting with AI who must not leak customer PII

Files never leave your device

Sanitize for AI runs entirely in your browser. mypdf.space never receives your PDF. After you paste into ChatGPT or another AI product, that provider’s terms and retention policies apply — we cannot control that step.

Limits worth knowing

No AI provider is controlled by mypdf — their policies apply after you leave this site.
Local sanitize is hygiene, not a compliance certification.
Images-only scans need OCR first.
