Free AI Image Upscaler - Locally Increase Resolution of Images

by•
So, I built this simple tool to offer unlimited 2x and 4x upscaling completely for free, with no signups, credit limits, or annoying paywalls, completely private. The best part? It runs entirely in your browser using your local GPU/CPU hardware (via WebGPU/WASM). Your images never leave your computer and are never uploaded to any server, making it 100% private.

I tested a few image upscalers before, and the biggest issue is usually losing natural details. How do you handle that while still improving image quality?

Nice launch! I like the local/private angle — no uploads is a strong selling point for image tools. Curious how it handles faces and small text, since that’s where most upscalers usually break.
