Quick guide

How to watermark multiple images

  1. Add your images

    Drop several files into the upload area or browse your device. The first image appears in the live preview.

  2. Set the watermark

    Enter text or choose a logo. Adjust its size, opacity, position, and whether it appears once or repeats across each image.

  3. Download the batch

    Choose an output format and download one ZIP containing the watermarked copies. Your original files are left untouched.

Image formats and output

JPEG, PNG, and WebP work in modern browsers. GIF, BMP, AVIF, SVG, HEIC, TIFF, and other formats work only if your browser can open them. Animated images are exported as a single still frame.

With “Original when possible,” JPEG, PNG, and WebP keep their format; other supported inputs export as PNG. You can also select PNG, JPEG, or WebP for the whole batch.

Privacy and image quality

Your images and logo are processed on your device; they are not uploaded to this site. The visitor counter records a browser visit, not your image files.

Exports are newly encoded images, so file size and quality can differ from the originals. Camera metadata may not carry over. Very large images or batches may exceed your device’s available memory.

Common questions

Can I use a transparent logo?

Yes. Choose “Logo image” and upload a transparent PNG or another image your browser can open. The transparency is preserved in the watermark.

What if one image cannot be opened?

The tool skips that file during export and reports how many were skipped. Try converting it to JPEG or PNG, then add it again.

Can I watermark images of different sizes together?

Yes. The watermark size scales relative to each image’s width, so the same settings apply throughout the batch.

Does a watermark prevent image theft?

A visible mark can show ownership, but it can still be cropped or edited. Use the repeated layout if you want the mark to cover more of the image.
