FAQ

Common questions

The tool supports all common web image formats, including JPEG, PNG, WebP, and GIF files. When adding a graphic watermark, uploading a transparent PNG logo ensures that your icon overlays cleanly without an unsightly white background box. You can also export your finished picture in your preferred output format.
Yes, you can switch between single-placement mode and repeating tile mode. In tiled mode, your watermark repeats diagonally or in a grid across the entire canvas, making unauthorized cropping or removal extremely difficult for image thieves while preserving preview transparency for prospective buyers.
The tool preserves your photo’s native dimensions and visual clarity by rendering the watermark layer directly onto the canvas at full original resolution. You can adjust output compression settings when downloading JPEG files to maintain optimal balance between file size and image sharpness.
All image rendering, canvas layering, and format conversions take place locally inside your web browser. Your private photos never leave your device and are never uploaded to cloud servers or stored in third-party file repositories. Closing the browser tab permanently flushes the image data.
