Choose a photo, pick a mode - Quick upscale 2x (about 8 MB model) or Restore & upscale 4x (about 55 MB model, also removes JPEG artifacts) - and click the button; the long edge is resized to 512px before processing so the AI model finishes in a reasonable time even on a large photo.
Example - low-res input and the 2x-upscaled result (generated ahead of time with the same on-device 2x model this page runs; your own photo is processed live in your browser):
AI Photo Restoration
freetoolonline.com editorial team
Sharpen, denoise, and upscale a blurry or compressed photo - 2x or 4x - right in this browser - no upload, no app to install.
Modes and first-run download
The first run downloads the model for the mode you picked once (about 8 MB for 2x, about 55 MB for 4x; cached offline after that); on the WASM fallback (no WebGPU) the 4x mode can take up to a minute to finish - the original photo previews immediately while you wait.
Private by design
Everything runs locally via Transformers.js / ONNX Runtime Web - the photo is never uploaded to a server; only the model weights load from the Hugging Face hub.
If something in the frame should go before you enlarge it - a stray object, a photobomber, a watermark - the object remover erases it first, the same way: entirely on your device, no upload.
Black-and-white originals pair the same way in the other direction: restore and upscale here first, then hand the clean scan to the photo colorizer to add predicted color - also fully on-device, no upload.
Frequently Asked Questions
What does AI Photo Restoration do?
Sharpen, denoise, and upscale a blurry or compressed photo - 2x or 4x - right in this browser - no upload, no app to install.
Can I use this as an AI image upscaler?
Yes. The Quick upscale 2x mode is a plain AI image upscaler for reasonably clean photos (about 8 MB model, several times faster), and the Restore & upscale 4x mode enlarges while also removing blur and JPEG blocking artifacts (about 55 MB model, slower). Both run entirely in your browser - the photo never leaves your device.
When should I reach for ai photo restoration?
When a photo is too small, too blurry, or shows JPEG blocking - before printing it, zooming in on it, or reusing it at a larger size. The original previews immediately; the first run downloads the model for the mode you picked once (cached offline after that), and on the WASM fallback (no WebGPU) the 4x mode can take up to a minute.
Does it repair scratches or colorize old photos?
No. These are fixed 2x/4x super-resolution models - they sharpen, denoise, and enlarge, but they do not remove scratches, tears, or stains, and they do not colorize a black-and-white photo.
What complementary tools work well alongside ai photo restoration?
The object remover erases a distraction from the frame before you upscale, and the face blur tool hides who someone is - both run on-device with no upload, like this page.
Which mode: quick 2x upscale or 4x restore?
Pick Quick upscale 2x when the photo is reasonably clean and you just need more pixels - a small avatar, an old web image, a picture you want to print larger. Its model is about 8 MB and runs several times faster than the 4x one. Pick Restore & upscale 4x when the photo is blurry or was saved with heavy JPEG compression: that model also removes blocking artifacts and sharpens edges while quadrupling the resolution. Neither mode repairs physical damage - scratches, tears, and stains stay - and a black-and-white photo stays black-and-white.
