Upload a JPG, PNG, or WebP image and upscale it 2× or 4× in your browser using high-quality interpolation with optional detail sharpening. This enlarges existing pixels—it is not generative AI. Files are not uploaded to a server.

How to use this tool

Worked example
Example: upscale a 500×500 icon by 2× to 1000×1000 for a presentation slide—edges may look softer than a native high-resolution source.
How it works
Upload a JPG, PNG, or WebP image and upscale it 2× or 4× using high-quality canvas interpolation in your browser. Optional detail enhancement applies a light sharpen pass after scaling. This is not generative AI—it enlarges pixels with smoothing, so very small sources may look soft.
Limitations
