How to upscale an image

  1. Add your images

    JPG, PNG, WebP or GIF, up to 20 at once. Each one shows its size in pixels.

  2. Choose 2× or 4×

    2× doubles the width and height (four times the pixels); 4× makes them four times larger. Pick the format to save in.

  3. Upscale and download

    Compare before and after, then download one by one or all together as a ZIP.

What AI upscaling can and can't do

Normal resizing stretches the pixels you have, so an enlarged picture looks soft and blocky. An AI upscaler has learned what real photos look like, so it redraws edges and textures at the new size. Small product photos, logos and old pictures usually come out noticeably cleaner.

It can't recover detail that was never captured: a blurry face stays a face that was blurry, only bigger and smoother. Text that's too small to read won't become readable. For the best result, start from the sharpest original you have.

This tool uses Real-ESRGAN, a well-known open-source upscaling model, running on your computer's graphics card when your browser allows it.

Questions about upscaling

Are my images uploaded?
No. The AI model is downloaded to your browser once (about 5 MB) and runs on your device. Your images are never sent to a server.
Why does the first image take longer?
The first time, your browser downloads the AI model and gets it ready. After that it's kept by your browser, so the next images and later visits start faster.
How large can my image be?
Up to 4 megapixels for 2× (for example 2000 × 2000 pixels) and up to 1 megapixel for 4× (for example 1000 × 1000 pixels). That keeps the result within what browsers can handle and the wait reasonable.
Should I choose 2× or 4×?
2× suits most photos and is quicker. 4× is best for very small images such as icons, thumbnails or a logo you only have in a small size.
Is it fast on my computer?
Small images take a few seconds. In our tests on an ordinary laptop, a 1-megapixel photo took about 15 seconds at 2× using the graphics card, and about 45 seconds when only the processor could be used. A dedicated graphics card is faster. You see the progress while it works.
Is it free?
Yes. No sign-up, no watermark and no premium tier.
