About this tool
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.
Example. A text string or a logo image is stamped onto each selected photo at the chosen position and opacity, then downloaded.
Limit. The stamp is applied to still images in one batch and is not burned into a video timeline.
