About this tool

A watermark shows who a photo belongs to and makes it harder to reuse images without permission. Photographers, online shops, real estate agents and clubs mark their pictures this way before sharing them online or with clients.

With this tool you add a text such as “© Your name” or your logo: in one of nine positions or as a slanted pattern across the whole image. Set size, opacity, color and rotation with sliders. You can process many images at once and download them one by one or together as a ZIP.

All images are processed in your browser only and are not uploaded. The watermark size follows the image width, so it looks equally proportioned on portrait and landscape photos.

How it works

  1. Drop one or more images into the field.
  2. Choose “Text” and enter your text, or choose “Logo” and load a logo file.
  3. Set size, opacity and position. For a pattern across the whole image, click “Pattern” and choose the rotation.
  4. Check the preview (click a file name to show that image) and download the images one by one or as a ZIP.

Frequently asked questions

Does a watermark really prevent image theft?

It deters and shows the origin, but it is not complete protection: a watermark in a corner can be cropped off. A semi-transparent pattern across the whole image is much harder to remove.

What format should the logo be?

Ideally PNG or SVG with a transparent background. A JPG logo always has a rectangular background that shows up as a box in the image.

Does image quality suffer?

JPG and WebP are re-compressed. At 90 % quality the difference is hardly visible. PNG is lossless, but much larger for photos. To shrink the files afterwards, use the Image Converter & Compressor.

Is the metadata kept?

No, the image is re-encoded when saved, so EXIF data such as camera, date and GPS location is dropped. Check a photo’s metadata beforehand with the EXIF Viewer & Editor.

How many images can I process at once?

There is no fixed limit. All images are kept in your browser’s memory; with very many large photos, creating the ZIP may take a moment on slower devices.
