What is a watermark and why should I add one?

A watermark is a text or logo overlay on an image that identifies ownership. Photographers, designers, and content creators use watermarks to protect their work from being shared or reused without credit.

What file format should I use for a logo watermark?

PNG with a transparent background works best. If your logo has a white or solid-color background, it will cover the underlying image at that area. Adjust opacity to make a solid-background logo blend more naturally.

Can I watermark multiple images at once?

Yes. Upload up to 50 images and apply the same watermark configuration to all of them. Download all results as a ZIP archive in one click.

Does adding a watermark upload my images?

No. Everything runs in your browser using the Canvas API. Your images and your logo stay on your device at all times.
