I'm a beginner developer from Japan.
I built this tool because I was tired of opening Photoshop just to redact a name or a face from a screenshot. I didn't want to use existing "free online tools" because uploading sensitive images to a random server felt unsafe.
So I built Kuro-Nuri ("Blacked Out" in Japanese). It runs entirely in the browser using WebAssembly and TensorFlow.js (for auto-detecting faces). No data leaves your device.
Features: - Drag & drop to auto-redact faces. - Client-side compression. - Removes Exif metadata automatically.
The code is still a bit messy as I'm learning, but I'd love to hear your feedback on the performance and usability.
Thanks!
