What Watermark images does
Watermark images protects your photos with a text (your name, your brand, “sample”, “confidential”) or with your logo. Pick the position on a 9-spot grid or a tilted tile pattern that covers the whole image, the size, color and opacity, and check the result in the preview before processing. It is applied the same way to every photo in the batch, sized in proportion to each one. It works with JPG, PNG, WEBP, AVIF, GIF, BMP, TIFF and HEIC, and everything runs in your browser.

Frequently asked questions
Can I use my logo with a transparent background?
Yes: choose “Logo or image” and upload a PNG or WEBP with transparency. The logo is scaled to a percentage of each photo's width, so it looks the same on large and small photos.
What is the tiled option for?
It repeats the watermark, tilted, over the whole image. It is harder to crop out or erase than a corner mark, so it suits documents or photos you share as samples.
Can the watermark be removed later?
Not from the new file: the mark is drawn into the pixels. Keep your originals without the mark; the tool never changes them.
Is there any quality loss?
PNG, BMP, TIFF and GIF lose nothing. JPG, WEBP and AVIF are saved again at high quality (92). The size in pixels doesn't change.
