- Click Download free PDF. The file is made on your device.

Frequently asked questions
Are my files uploaded to a server?
No. Your files are opened and processed entirely in your browser using JavaScript. Nothing is uploaded, so it is safe for private documents and works even on slow connections.
Is it free? Are there limits?
Yes, it is free with no sign-up and no watermark. The only limit is your device memory, so very large files (hundreds of MB) may be slow.
What if I forget the password?
It cannot be recovered. We never see or store it, so keep it somewhere safe or keep an unprotected copy.
Are the print and copy restrictions secure?
They are followed by most PDF viewers, but some software ignores them. The open password is the real protection; the restrictions are a polite request.
