FAQ
Can I use any text?
Yes — enter any text (including non-Latin scripts) as the watermark.
Can the watermark be removed later?
It is embedded into the page and can't be easily removed — keep a backup of the original.
Are my files really not uploaded?
Yes. This tool processes files locally in your browser using built-in capabilities; file contents are never sent to any server. Verify in the DevTools Network panel — no upload request appears during processing.
Is it free? Any signup or limits?
Completely free, unlimited, no signup required. File size is limited only by device memory; process very large files on a computer.
