Secure PDF
Add or remove passwords, redact, and sign — with real AES-256, in your browser.
About secure pdf
This is the segment where uploading is least defensible and most common. A password-protected bank statement or Aadhaar PDF is precisely the document you should never hand to a free website, yet almost every "remove PDF password" service requires exactly that — you send them the file and the password. These tools use qpdf compiled to WebAssembly, which performs genuine AES-256 encryption and decryption locally. The file and the password both stay in your tab.
Common questions
Are these tools really free?
Yes, all 0 of them, with no signup, no watermark and no file limits. There is no premium tier holding features back. The site is supported by advertising, not by charging you for the tool.
Do I need to install anything?
No. Everything runs in your browser using standard web APIs. No app, no extension, no account.
Are my files uploaded to a server?
No. Every tool in this category processes your data inside your own browser tab. You can verify this in your browser's Network tab — there is no upload request because there is no server.
Do these work on a phone?
Yes. Every tool is mobile-first and touch-friendly. Heavy operations — rendering large PDFs, processing very large images — will be slower on a phone than a laptop, because the work happens on your device.
