How to watermark photos in bulk

Drop in your photos, or press Choose a folder.
Type your text or pick your logo, then choose the position, size and opacity. Press Preview to check it.
Press Add watermark, then download the photos one by one or all as a ZIP that keeps your folder layout.

🔒 Your photos and logo are processed by your own browser and are never uploaded to our server.

The size is set as a share of each image's width, so the watermark looks the same on big and small photos.
Automatic text: {filename}, {date} and {n} (the photo's number in the list) are filled in for each photo. For example, © Jane Doe {date}.
Tiled repeats the watermark across the whole photo, which makes it hard to crop out. It's great for proofs.
