Add a logo or image watermark to photos in the browser with position, size, opacity and batch processing.
Files are not sent to a server. Processing runs in your browser, and the queue handles one file at a time so the device stays responsive.

How to use it
Add photos and a logo file. The first uploaded file is used as the logo for the rest; if the first file is processed, the editor uses the second file as the logo.
Recommended settings
PNG or WEBP with transparency works best. For bottom right, start with X 82%, Y 82%, size 22% and opacity 90%.
Privacy
Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.
Limits
Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
