Frequently asked questions
Is it free?
Yes. Free with no sign-up, no watermark and no hidden limits on pages or files beyond what your device can handle.
Are my files uploaded?
No. This tool runs entirely in your browser – your file never leaves your device and works even with a weak connection once the page has loaded.
Can the watermark be removed?
It's drawn onto each page, so casual removal is hard, but no watermark is impossible to remove. For stronger protection, also use Protect PDF.
Does it work with password-protected PDFs?
Unlock the PDF first with our Unlock PDF tool (you need to know the password), then come back.
Does it work on my phone?
Yes. It works in any modern browser on iPhone, Android, Windows and Mac.
