Why ImgScale

Everything you'd pay for — free

Most upscalers cap quality behind a login or upload your files. We do neither.

CORE

Up to 4× AI scale

Real-ESRGAN-style models rebuild edges and texture naturally — no harsh halos or artifacts.

Nothing stored

The AI upscaler processes your photo on our secure server and deletes it the moment your result is ready. The 16 other tools run 100% in your browser.

No signup, instant

No account, no email, no waiting. Open a tool and use it right now — unlimited batches too.

The toolkit

One upload, seventeen free image tools

Upscaling is what we do best — the rest are free bonuses for the same images.

PixelLab — Creative Tools

Five more free tools for creative image work — pixel art, GIF editing, ASCII art, color extraction, and photo framing.

Questions

Good to know

Is ImgScale really free?+

Yes. ImgScale is completely free — no account, no cost, and no limits. Ads on our guide pages keep it that way.

Do my images get uploaded?+

Only the AI upscaler uses a server: your photo is sent over an encrypted connection to our GPU server, upscaled, returned, and deleted right away — never stored or used for training. All 16 other tools process images entirely on your device.

What's the difference between 2× and 4×?+

2× doubles each dimension and looks most natural; 4× quadruples it for small sources or print, but asks the model to invent more detail.

Which formats are supported?+

Upload PNG, JPG, or WEBP, and download your result in any of those with adjustable quality.

Can I process several at once?+

Yes. Drop multiple files to queue a batch, process together, and download everything as a single ZIP.
