Frequently asked questions
Is my PDF uploaded?
No. The watermark is added in your browser, so the file stays on your device.
Will the watermark cover my text?
It is semi-transparent, so the content underneath stays readable. Choose Light opacity for a subtle mark or Strong to make copying harder.
Can I use other languages?
The watermark uses a standard PDF font that supports English letters, numbers and common symbols.
Can someone remove the watermark?
It is drawn onto each page, which stops casual reuse. Determined users with PDF editors can still edit pages, so don’t rely on it as the only protection.
