Frequently asked questions
No. The tool runs entirely in your browser using an HTML canvas. The photo you open and any logo you add stay on your device and are never sent to a server.
You pick one mode at a time — a text watermark or a logo image — but you can run the tool twice: download the text-watermarked image, then load that result back in and add your logo on top.
It downloads as a PNG. PNG preserves the transparency of semi-opaque text and logos, so the watermark blends correctly instead of being flattened onto a solid background like JPEG would do.
Yes. The text and logo size are set as a percentage of your image, and the position keeps a proportional margin from the edges, so the watermark scales sensibly whether the photo is 800px or 4000px wide.
