Free PNG to BMP converter online
Need a BMP instead of a PNG? This free converter turns PNG 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.
PNG is a lossless format: it never throws image data away, so text and sharp edges stay crisp and it supports full transparency. The trade-off is file size: a photo saved as PNG is often 5 to 10 times bigger than the same photo as JPG. PNG files can hold hidden text chunks with software names, authors and dates.
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.
