Add Watermark to Image puts your name, website or logo on photos before you share them. Everything runs in your browser, so your photos are not uploaded.

How to Use#

Drop one or more JPG, PNG or WebP photos onto the tool.
Choose the Text or Logo tab.
- Text: type in Watermark text (it starts as "© Your Name"), set Font size and Colour.
- Logo: choose a file under Logo image and set Logo size.
Adjust Opacity (50% by default) and Rotation (-45° to 45°).
Pick a Position: one of nine spots such as Top left, Centre or Bottom right (the default), or Tile across image. Use Margin to move a placed mark away from the edge, or Spacing to spread tiles out.
Click a file name in the list to preview it, then click Download for one photo or Download all (ZIP) for the batch.

Things to know#

Size is relative: font and logo size are set as a % of image width, so the mark looks the same on photos of different sizes.
Output: downloads keep the original resolution and format. WebP stays WebP where your browser can save WebP (Safari saves PNG instead). The preview is scaled down.
Downloads are disabled until there is watermark text, or a logo has been chosen.
File limit: up to 25 MB per photo.
Privacy: photos and logos stay on your device.

Tips#

The logo can be a PNG (transparent works best), WebP or JPEG. A transparent PNG looks cleanest.
For proofs, tile a word such as SAMPLE or DRAFT at around 30-45° rotation so it is hard to crop out.
White text at 40-60% opacity is visible on most photos without hiding the subject.
