Batch Watermark
Protect and sign your photos in one go: add your name or logo as a watermark to a whole set of images, set its position, size and transparency, then download everything as a ZIP.
About this tool
This tool applies the same watermark to every image you drop in, at a size proportional to each one: a small portrait and a large photo get a mark that looks the same. The watermark can be one or two lines of text (font, bold, italic, colour, outline, shadow) or your logo, ideally a transparent PNG. Place it once, in one of nine positions with a margin, or as a repeated pattern over the whole image, with adjustable spacing and every other row offset.
Opacity and angle are fully adjustable and the preview updates as you change the settings; click a thumbnail to check the result on each photo. Images keep their original resolution and are saved as JPG, PNG or WebP, with the quality you choose and a suffix added to the name. Photographers, online shops, estate agents and content creators can mark their visuals before publishing, without uploading anything: everything is computed in your browser.
