MarkGone - Remove image watermarks in your browser — free & private

> Hi PH! 👋 I'm KuiGe, an iOS engineer and indie developer (I also make PicSqueeze, an in-browser image compressor). > > I built MarkGone because every "free online watermark remover" I tried had the same catch: you upload your private photos to someone's server, wait in a queue, and then hit a paywall or download limit — or the output is stamped with *their* watermark. That always felt backwards for something that is just math on pixels. > > Three things that make MarkGone different: > > 1. 🔒 **100% local** — decoding, masking and inpainting all run in Web Workers on your device. Nothing is uploaded, and the page works offline once loaded. > 2. ⚡ **Real batch mode** — mark the watermark once, apply the mask to the whole batch with one click, then process up to 50 images in parallel and grab everything as a ZIP. > 3. 🧠 **An actual inpainting engine** — three tiers (fast diffusion / Telea FMM / pyramid refinement for large areas), not a blur patch. Free, unlimited, no watermark on the output. > > It's a single HTML file with zero external dependencies. Click "Try with demo images" — two sample photos are generated locally, so you can see it work in ~10 seconds without giving up any files. > > Happy to answer questions about the inpainting pipeline. And if you try it on your own images, I'd love to hear which watermark types it handles well (and where it struggles) — that's exactly the feedback that drives the roadmap!
