What Image Upscaler does
Make a small image bigger without it turning into blocky pixels. Pick 2x, 3x or 4x, optionally add sharpening, and download the larger JPG, PNG or WebP. The work happens in your browser; your image is never uploaded.
How to use it
- Upload an image.
- Choose the scale factor and how much sharpening to apply.
- Click Upscale, check the result and download it.
Good to know
This uses smooth resampling and sharpening, not AI. It makes images larger and cleaner-looking, but it can't invent detail that isn't in the original. Output is limited to 12,000 px per side to protect your browser's memory.
