Add Logo Watermark to Image

This page opens the watermark tool in logo mode: upload your logo as a second image — a PNG with a transparent background works best — and it is composited over the photo at the size, opacity and position you choose. The logo scales relative to the photo width, so the same settings produce a consistent look across images of different resolutions.

A logo watermark reads as more professional than plain text: brands, studios and marketplaces use a semi-transparent logo in a corner (usually bottom-right at 30–50% opacity) so the mark identifies the source without distracting from the subject. For stronger protection you can rotate it 45° or switch the position to tiling so copies of the logo cover the whole frame.

Select the photos, upload the logo once and process them all in one batch — each image keeps its own name with a -watermark suffix and gets a separate download link. Everything runs in your browser via the canvas API, so neither the photos nor your logo are uploaded anywhere.
