Watermark Image puts your name, website or logo on a photo, or on a whole folder of them at once. Place it in any corner, along an edge, in the centre, or tile it diagonally across the picture. Size and opacity scale with each photo, so a mark set on one image looks the same on the rest. Everything happens in your browser.

How to use it

  1. Choose one or more photos, drop them here, or paste them.
  2. Type your watermark text, or switch to Logo image and pick a file.
  3. Set the size, opacity and position. Tap a thumbnail to check another photo.
  4. Download the image, or download them all as a zip.

Frequently asked questions

Are my photos uploaded anywhere?

No. The watermark is drawn on a canvas in your browser and the files are saved straight from this tab. Your photos never leave your device.

Can I watermark many photos at once?

Yes. Add as many as your device can handle, check the preview on any of them, then download them all as one zip. Each photo keeps its own size, and the watermark scales with it.

Can I use my logo instead of text?

Yes. Choose Logo image and pick a file. A PNG with a transparent background looks best, since anything opaque around the logo shows as a box.

What does Tiled diagonal do?

It repeats the watermark across the whole photo at an angle. That is much harder to crop or paint out than a single mark in a corner, which suits proofs and previews.

Will the quality drop?

JPG and WebP photos are saved again at 92% quality, which is hard to tell apart from the original. PNGs stay lossless. iPhone HEIC photos come out as JPG.
