Files never leave your device
Your PDF is processed in this browser tab. Files never leave your device, and mypdf.space does not receive uploads. No account, no watermark, no server-side copy.
Limits worth knowing
- Deep Clean does not destroy visible page text under fake black boxes — use Redact for that.
- Not a forensic wipe of every possible stream.
- Bookmarks and some structures may be dropped.
