About These Formats
Converting BMP to PNG is the smartest move when you want to shrink huge BMP files but cannot tolerate any loss of pixel data. BMP stores raw, uncompressed pixel data, which is wasteful: a 50 MB BMP frequently compresses down to 5 to 15 MB as PNG with zero degradation, because PNG applies lossless DEFLATE compression to identical pixel data. The conversion is mathematically reversible for the visible RGB values, making it ideal for archival, technical illustration, screenshots of interfaces, and any image where text legibility or pixel-perfect lines matter. Unlike BMP, PNG also supports alpha transparency, gamma correction, and standardized color profiles, so you gain capability while losing nothing. Typical scenarios include archiving the output of legacy Windows scanning tools, normalizing BMP exports from CAD or GIS software into a more modern format, and posting screenshots in tools that reject the BMP MIME type. PNG is universally supported across browsers, operating systems, mobile devices, office suites, and chat platforms. WeLoveConvert decodes BMP and re-encodes as PNG directly in your browser, with no server roundtrip. For minimum file size, prefer the higher compression presets if exposed in the export options.

Common Issues
- infoTransparent BMP variants are rare, so alpha gain rarely applies
- infoFile size shrinks but may still be large compared to JPG for photos
- infoPNG may reveal subtle artifacts that were hidden in uncompressed BMP
- infoBMP files lack EXIF, so the resulting PNG carries no camera metadata
