Convert PNG to BMP Online Free & Fast
Turn your PNG images into BMP files in seconds. No installs, no software just upload, convert and download.
This tool converts PNG images into BMP format directly in your browser. Unlike converting from JPG, this is a lossless-to-lossless conversion: PNG and BMP can both store an image with zero quality loss, so the visual result should be pixel-for-pixel identical to your original. The trade-off is file size BMP typically stores images uncompressed, so the resulting file is usually several times larger than the PNG, with no visual benefit for the extra size. Transparency handling can also vary: some BMP variants support an alpha channel and some don't, so if your PNG has transparency, check the result to confirm it came through as expected. Upload your file and download a BMP in seconds; it's deleted automatically within an hour.
How It Works
- Upload your PNG Drag and drop or browse to select your file.
- Convert to BMP Convert Omni processes it automatically.
- Download your BMP Your converted file is ready in seconds.
Why Convert PNG to BMP
- Legacy Windows software. Some older applications, printer drivers or embedded systems only accept BMP files.
- Pixel-perfect precision. Since both PNG and BMP are lossless, converting between them doesn't touch image quality at all.
- Technical and scientific tools. Certain CAD, imaging or analysis software still expects uncompressed BMP input.
- Simple, predictable pixel data. BMP's lack of compression makes it useful for some programming, testing or low-level image-processing tasks.
Frequently Asked Questions
Will converting PNG to BMP change my image quality?
No. Both PNG and BMP are lossless, so this conversion doesn't discard any image data the result should be visually identical to your original PNG.
Will my PNG's transparency carry over to the BMP?
It depends. Some BMP variants support an alpha channel and some don't, and support varies by the software that opens the file. If your PNG has transparency, it's worth checking the converted BMP to confirm it came through as expected.
Why is the BMP file so much bigger than my PNG?
PNG uses lossless compression to keep files small, while BMP typically stores images uncompressed. A BMP version of the same image is often several times larger, with no difference in visual quality.
When would I actually need a BMP file?
Mainly for compatibility with older Windows software, certain technical or scientific applications, printer drivers or workflows that specifically require an uncompressed bitmap.
Is there a limit on how many PNGs I can convert?
The free plan allows 10 conversions a day for files up to 10 MB. Paid plans remove the daily limit and raise the file-size cap.
Is it safe to upload my PNG files?
Yes. Conversion is automated, uploads are encrypted (HTTPS/TLS) and every file is permanently deleted within 60 minutes. Your images are never used to train AI models.
