AI image upscaler (2x and 4x)
That small photo that needs to grow? AI upscales it 2x or 4x rebuilding the details, right in your browser. Compare before and after prior to downloading.
on the first photo, the AI engine (~6 MB) is downloaded — after that it stays saved in your browser.
Processed in your browser — your files never leave your computer.
How it works
-
Drop your photo here
Drag a JPG, PNG or WebP onto the dotted area, or click to choose. For 2x, the longest side can be up to 1200 px; for 4x, up to 600 px — the tool checks and warns you.
-
Pick 2x or 4x
Select how much to upscale and click "Upscale". On the first photo, the AI engine (~6 MB) is downloaded and stays saved in your browser; the bar shows real progress.
-
Compare and download
See the before and after side by side and download the upscaled PNG, with double (or quadruple) the dimensions of the original photo.
Frequently asked questions
Is it magic? Will any photo come out perfect?
No. The AI rebuilds plausible details while enlarging — edges, textures, strokes — and works well with a decent photo that just needs to grow, drawings and screenshots. What it cannot do is invent what never existed: a tiny, shaky or heavily compressed photo will not become a sharp studio shot.
Why is it in beta?
Because running AI inside the browser is heavy and results vary with the photo type and the device — on a modest phone it can take a while. The tool works, but it is still being tuned; the beta badge is the honest way to say that.
Why is there an input size limit?
Because the processing happens on your device: an image over the limit would freeze the browser. That is why 2x accepts a longest side of up to 1200 px and 4x up to 600 px. Bigger photo? Crop the part that matters or use 2x.
Is my photo uploaded to a server?
No. The upscaling happens inside your browser, on your device. The only download is the AI engine (~6 MB), the first time — your photo never leaves your computer.
What format does the result come in?
Always PNG — no lossy compression on top of what the AI generated. JPG, PNG or WebP goes in; PNG comes out with the dimensions multiplied, shown in the proof (e.g. 800×600 → 1600×1200).
