Pixel Up: AI photo upscaler and restorer that keeps faces real

Hey Product Hunt 👋 I built Pixel Up because most "AI photo enhancers" don't enhance — they repaint. Run an old family photo through one and you often get back a sharper picture of someone who isn't quite your grandmother. Pixel Up is built the other way round. The upscaler is a real super-resolution model (Real-ESRGAN with a face-restoration pass), so it adds pixels that agree with the ones already there instead of inventing new ones. The other tools — restore, colorize, sharpen, enhance face, remove scratches, remove objects — are tuned to change only what you asked for and keep identity, framing and expression exactly as they were. What you can do: • Upscale 2x, up to 4800px on the long edge • Restore faded, damaged old photos • Colorize black-and-white prints • Unblur and sharpen, enhance faces • Remove scratches, dust and unwanted objects • Plus a library of AI photo and video effects Everything runs in the browser — no app to install — and downloads are full resolution with no watermark. It's in English, 简体中文 and 繁體中文. I'd love your feedback, especially on photos where other tools let you down. Old family photos are the best test. 🙏
