Sign your work. Invisible. Verifiable.
wmgg is an invisible watermarking tool (blind watermark) for images and videos. Unlike cloud watermark services, wmgg processes files 100% locally in your browser — your files never leave your device. 100% local, 0% uploads.
Drag any file into the interface and embed a watermark with one click. Supports JPG, PNG, WebP, MP4, MOV, MKV, WebM, and TS formats. Watermarks withstand screenshots, compression, rotation, and cropping — so you can prove ownership even after your work has been shared and re-edited.
Extraction is always free and needs no original file. Optional encryption protects watermark content with a key. Available as a web app, Photoshop plugin (UXP), Photopea plugin, Canva plugin, and Chrome extension.
Free tier: 50 tokens on signup + 30 daily refills. Pro $4.99/month, Max $69.99/year.
