Upscale 2x
Double the resolution of any image using AI super-resolution — runs on your device.
About Upscale 2x
Upscale 2x doubles an image's resolution using AI super-resolution, reconstructing detail rather than just stretching pixels. Use it to enlarge a small photo, sharpen a low-res asset, or rescue an image that's too small for print or display. The model runs on your device, so your image is never uploaded.

Common uses
- Enlarge a small product or thumbnail image so it holds up at a bigger display size
- Recover detail in a low-resolution photo before printing it
- Bump up an old or downscaled image so it looks crisp on a high-DPI screen
- Upscale a logo or graphic that only exists at a small size
- Prepare a sharper version of an image for a presentation or banner
- Get more usable pixels out of a cropped section that came out too small
Frequently asked questions
How much bigger does the image get?
It doubles both width and height (2x), so a 500x500 image becomes 1000x1000 — four times the total pixels.
What formats are supported?
JPEG, PNG, and WebP inputs are accepted, and the output is a PNG to preserve the reconstructed detail.
Is this just stretching the image?
No — it uses AI super-resolution to infer plausible detail, which looks far sharper than a plain resize. Results vary with the source quality.
Does my image get uploaded?
No. The upscaling model runs entirely in your browser on your device, so the image never leaves it.
Can I go beyond 2x or get even sharper results?
This tool is fixed at 2x. For 4x or sharper output on large inputs, the hosted Real-ESRGAN Pro version does the heavy lifting on a GPU.
