Convert PNG to BMP
Updated Jul 2026
PNG is a compressed image format that almost everything opens today, while BMP is an older Windows bitmap format that stores every pixel uncompressed. To convert PNG to BMP, open the file in a converter and export it as BMP. Doing this on your own computer means the image never has to leave your machine.

PNG vs BMP: what actually changes
| PNG | BMP | |
|---|---|---|
| File size | Smaller, compressed | Much larger, stores every pixel uncompressed |
| Quality | Lossless | Lossless, no quality lost converting |
| Transparency | Yes | No, transparent areas fill in with a solid color |
| Opens everywhere | Yes, on phones, browsers, and modern apps | Mostly older Windows programs, not the web |
| Metadata | Can carry text and color information | Very little, just basic image dimensions |
When to convert, and when not to
Convert PNG to BMP when an older Windows program, a piece of legacy software, or a specific tool you're feeding a file into asks for a bitmap and won't take anything else.
Keep the PNG if you're sharing it, posting it online, or need transparency, since BMP files are far larger and drop any transparent areas.
Why not just use an online converter?
PNG files are often screenshots, logos, or UI assets, the kind of thing you don't necessarily want passing through someone else's server. An online converter uploads your image to convert it. Morphjet converts the file right there on your own computer, so it never has to travel over the internet at all.
Questions
Does converting PNG to BMP lose quality?
No. Both formats are lossless, so the pixels come through exactly as they were. What changes is the file size, not the image quality.
Will the BMP keep the PNG's transparency?
No. Standard BMP doesn't support an alpha channel the way PNG does, so any transparent areas get filled in with a solid color, usually white.
Why is the BMP file so much bigger than the PNG?
PNG compresses the image data, while BMP typically stores it uncompressed, pixel by pixel. A PNG that's a few hundred kilobytes can turn into several megabytes as a BMP.
Does the BMP keep the PNG's metadata?
Basically none of it. BMP's header only holds the image dimensions and color format, so any text or color profile information in the PNG doesn't carry over.
Can I convert PNG to BMP without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never leaves your machine. You could even do it with your wifi off.
Morphjet converts PNG, BMP, and 1,800+ other formats, all on your machine. Launching this July.
