Convert BMP bitmap images to compressed PNG format instantly in your browser. Smaller files, full quality, nothing uploaded.
Why Convert BMP to PNG?
BMP (Bitmap) is a legacy Windows format with no compression — a 10 megapixel BMP can easily be 30 MB or more. PNG stores the exact same pixel data losslessly but uses compression to shrink the file by 60–95% depending on image content. The result is pixel-perfect identical to the BMP at a fraction of the size, and PNG is supported by every modern operating system, browser, and design application.
BMP vs PNG at a Glance
| Feature | BMP | PNG |
|---|---|---|
| Compression | None (raw pixels) | Lossless (deflate) |
| File size | Very large | 60–95% smaller |
| Transparency | Limited | Full alpha channel |
| Web support | No | Universal |
| Quality loss | None | None |
When to Use PNG Instead of BMP
Always. There is no situation where BMP is preferable to PNG — PNG is smaller, more compatible, and equally lossless. BMP files are typically created by older Windows software (Paint, screen capture tools) and should be converted to PNG before sharing, archiving, or uploading anywhere.
