Upscale images with AI
Small or blurry photos, doubled or quadrupled in size. Free, unlimited, never uploaded.
Drop images here or click to browse
Up to 2 MP per image. The AI model downloads once. Your photos stay on your device.
Why this beats per-image credit services
Most AI upscalers run on servers. Servers cost money, so they sell credits, add watermarks or cap your resolution. QuietPix ships the neural network to your browser instead. Your hardware does the work, your photos stay yours, and the tool stays free. Old family photos, tiny logos, game textures, product shots: batch them all for $0.
Frequently asked questions
How does AI upscaling work?
A super-resolution neural network (Swin2SR) predicts the detail that a bigger version of your image would have. It runs on your device, so your photos are never uploaded. 2x doubles width and height. 4x is tuned for real-world photos.
Is it really free and unlimited?
Yes. The AI runs on your hardware, so we have no per-image costs. No credits, no watermark, no signup.
Why is there a 2 MP input limit?
Super-resolution is heavy math. Two megapixels keeps results fast on normal computers. For a bigger photo, resize it down first, then upscale it back up.
When should I pick 2x vs 4x?
2x is fast and works on everything: logos, screenshots, graphics, photos. 4x uses a model tuned for real-world photos and shines on small, blurry pictures.
