  3. 03

    Place & style it

    Drag the mark anywhere, then set its size, opacity and tint to suit the photo.

  4. 04

    Export

Why use it

Full-resolution output

Watermarks are applied at the photo's native size — no downscaling, no quality loss.

Batch in one go

Watermark many photos with the same mark and download them all as a ZIP.

Private by default

Photos are processed in your browser and never uploaded to a server.

Great for

  • Protecting photography and artwork before sharing
  • Branding product shots for a shop or listing
  • Marking proofs sent to clients

Frequently asked

Are my photos uploaded anywhere?
No. Watermarking happens entirely in your browser, so your photos stay on your device.
Can I watermark lots of photos at once?
Yes — add a batch, apply your mark, and export them together as a ZIP.
Can I control how strong the watermark looks?
Yes — adjust the size, opacity and tint so it's visible but not distracting.
