Frequently Asked Questions

Common questions about the free online image upscaler.

Choose your photo, pick two, three or four times in the scale menu, then click the download link to save the enlarged PNG.
No. The image is decoded with the browser File API and enlarged on a local canvas, so it never leaves your device.
It redraws the photo at a larger size with smooth high quality resampling, so the enlarged copy looks clean rather than blocky.

Very large canvases can freeze a browser tab. The tool caps the longest side so the preview and the download stay quick and reliable.
Slightly soft edges are normal at large factors. Progressive doubling keeps the result smoother than a single hard jump in size.
You can open any format your browser supports, including JPG, PNG, WebP, GIF and BMP. The result is always saved as a PNG.
