Free AVIF to BMP converter online
Need a BMP instead of a AVIF? This free converter turns AVIF files into BMP images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.
AVIF is the newest mainstream image format, based on the AV1 video codec. It often beats WebP by another 20 percent in file size and supports HDR and transparency. Support outside of modern browsers is still patchy, so AVIF files frequently need converting before they can be edited, printed or uploaded.
BMP is an uncompressed bitmap format from early Windows. Because it stores every pixel raw, BMP files are enormous (a 12 megapixel photo is about 36 MB) but they are trivially simple, so old software, microcontrollers, label printers and some games still require them.
