How to use it

Add a watermark in four steps

  1. Upload the image you want to mark.
  2. Enter text or upload a logo.
  3. Adjust placement, size, opacity, and tiling.
  4. Preview and download the finished image.

Flexible branding

One mark or full-image coverage

Use a corner mark for subtle attribution, center a logo for previews, or tile a lower-opacity watermark across the image for broader protection.

How to use it

Know before you start

Important limitations

  • Very faint marks can disappear after resizing or recompression, while opaque marks may obscure important content.
  • A watermark does not register copyright or prove authorship by itself.
  • Canvas export may remove the source image's metadata and animation.
