Batch watermark your photos

Upload your logo once, then drop in the whole batch — it lands in the same spot at the same size on every photo. Runs in your browser; the photos never leave your machine.

Your logo

A PNG with a transparent background works best. The logo keeps its aspect ratio and scales to each photo's width, so the whole batch looks consistent even when the originals differ in size.
