About Resize Image to 512×512

Five hundred and twelve pixels square is the classic icon and app-asset size - a power of two that scales down cleanly to every smaller icon. As a power of two, five hundred and twelve downsamples cleanly to 256, 128, 64 and every smaller icon without the blurring that awkward ratios cause, which is precisely why app stores and icon pipelines demand a 512 master. Game engines and launcher formats expect this size for the same reason. Treat it as the source from which a whole family of smaller icons is generated. App stores, game assets and icon sets commonly require a 512×512 source. This tool resizes any image to exactly 512×512 pixels and does it entirely in the browser - the picture is decoded, scaled and returned without being uploaded anywhere. Because the target is fixed dimensions rather than a fixed file size, it scales to fill 512×512 and covers the frame where the source is a different shape, so the whole area is used rather than left with borders.

Check the image before download

Filling a 512×512 square from a non-square source trims the overflowing edges. If precisely what stays matters, crop the image first, then resize.
Enlarging a source smaller than 512×512 cannot invent detail and will look soft, so start from an image at least 512×512. The output is a JPG and drops the original's metadata such as camera model and GPS, which is usually welcome before sharing.
