Watermark image. In your browser.
Add your name or copyright over a photo — position, size, colour and opacity, or tile it across the whole image. It happens right in your browser, so the image is never uploaded.

Common questions
Is my image uploaded?+
No — the entire watermark is drawn on a canvas in your browser, so the image never leaves your device. Nothing is sent to a server.
Can I tile the watermark?+
Yes — tick 'Tile' to repeat the text diagonally across the whole image, which is much harder to crop out than a single corner mark.
Can I add a logo image?+
This tool does text watermarks. For a logo, export a PNG of your logo as the text-free base and overlay it in an editor — or use a semi-transparent text mark, which covers most needs.
Free, no watermark-on-the-watermark?+
Right — it adds only YOUR watermark. No FileWhirl branding, no signup, free.
