Can I use a logo as the watermark?

Yes. Switch to Image watermark mode and drop a PNG with transparency. The logo is scaled to the chosen size percentage of the base image width and positioned at your chosen anchor.

Tile repeats the watermark in a diagonal pattern across the whole image — perfect for proofing or stock-sample overlays. The tile angle is fixed at -30° for text and grid-aligned for image watermarks.

Is the watermark removable?

No — the watermark is baked into the pixel data when the canvas exports. Treat it as permanent for recipients.

Does it preserve transparency?

Yes if you choose PNG or WebP output. JPEG output fills transparent areas with white because the format doesn't support alpha.

Are my images uploaded?

No. Watermarking happens entirely in your browser using the Canvas API. Nothing leaves your device.
