Watermark images

Add your shop name, © text or logo to photos so nobody can reuse them — with font, colour, size, opacity, angle, position, shadow and a live preview.

⭐ Use this often? Press Ctrl+D (⌘+D on Mac) to bookmark it — next time it is one click away.

How to use

  1. Add images (many at once is fine).
  2. Type your text or upload a logo, then pick font, colour, size, opacity, angle and position — check the preview.
  3. Press Start and download.

Questions

Are my files uploaded anywhere?
No. Everything runs inside your browser on your own device. Your files are never sent to our servers.
Is it free?
Yes. No sign-up, no watermark, no limit on how many times you use it.
