Frequently asked questions
Can I use my own logo?
This tool adds text watermarks. Latin letters, numbers and common symbols are supported.
Can the watermark be removed afterwards?
It is drawn onto the page, so keep your original file if you need a clean copy.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
