Watermark many photos at once

Watermark a whole set of photos in one go: a shoot, a product range or a portfolio. Your text or logo is sized to each photo’s width, so it looks the same on every image, landscape or portrait.

Up to 50 JPG, PNG, WebP, GIF or AVIF images, 80 MB each. You can also paste images.

Processed on your device. Your images are never uploaded.

    How it works

    1. Your browser decodes each photo in turn, at full resolution.
    2. It draws the same text or logo on each one, in the position, size and opacity you set.
    3. The watermarked copies are saved one by one and offered individually or as a ZIP. Your originals are untouched.

    • The watermark is sized as a share of each image’s width, so it looks the same on large and small photos.
    • For a logo, any image works. A PNG with a transparent background looks best.
    • Metadata such as camera details and location is not copied to the new files.

    Your image stays on your device

    This tool runs entirely in your browser. The image is never uploaded, so there is nothing for us to store, see or delete.

    To check, open your browser’s developer tools, switch to the Network tab and use the tool: you will not see your image being sent anywhere.

    Questions

    Are my images uploaded anywhere?

    No. The image is read and processed by your own browser. Nothing is sent to our servers, so there is no copy of your image anywhere but your own device.

    Will the watermark look the same on portrait and landscape photos?

    It’s sized as a share of each photo’s width, so it takes up the same proportion of every image’s width. On a portrait photo it is a little smaller relative to the height.

    Can I change the settings after adding the photos?

    Yes. Change anything and every photo is watermarked again with the new settings.
