About AI Image Upscaler
The upscaler uses an open-source super-resolution model that rebuilds fine texture instead of just stretching pixels. It improves old, small or compressed images noticeably. Added detail is a plausible guess, so faces and text can be wrong; do not use it for evidence. Large images are slow on weak devices.
FAQ
Why is it slow on big images?
The model runs on your own processor in tiles, so large images take longer; start with smaller ones.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
