Convert PNG to BMP
Free online PNG to BMP converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert PNG to BMP?
PNG and BMP are both lossless, so nothing is lost by converting between them. The usual reason for this trip is software, often an older imaging pipeline or embedded device, that specifically expects a raw .bmp file and won't open PNG's compressed container. Expect the BMP to be noticeably larger, since you're trading PNG's compression for BMP's bulkier but widely readable raw format.
Tips
- Expect a large output file. BMP is uncompressed.
- Use only when a target app requires .bmp.
Both formats are lossless. Check whether you need BMP
PNG and BMP share something most other pairs on this site don't: neither throws away image detail. PNG does that through real compression. BMP does it by not compressing at all. Before converting, check whether the software asking for BMP would accept PNG instead. Many tools that historically defaulted to BMP have added PNG support over the years. If the target only reads .bmp, this conversion is safe. You won't lose detail. You will gain file size.
