Why convert BMP to PNG?
BMP files are uncompressed and very large. PNG keeps the image identical but applies lossless compression to shrink it dramatically, and it works on the web and in modern apps where BMP often isn't supported.
Is PNG smaller than BMP?
Yes, usually far smaller. BMP stores raw, uncompressed pixels, while PNG compresses losslessly — so you get the same image at a fraction of the file size with zero quality loss.
Is this BMP to PNG converter free and private?
Yes. It is completely free, with no signup, no watermark, and no limit on how many files you convert. Every conversion happens locally on your device, so your images are never uploaded to a server. Read more in our privacy policy.
Frequently asked questions
- Will I lose quality converting BMP to PNG?
- No. PNG is lossless, so the converted image is pixel-for-pixel identical to the BMP — just compressed.
- Why use PNG instead of BMP?
- PNG is much smaller, supports transparency, and is supported on the web and in modern software, where BMP frequently is not.
- Do you upload my BMP files?
- No. All BMP to PNG conversion happens locally in your browser — your files are never uploaded, stored, or seen by us.
- Can I convert several BMP files at once?
- Yes. There is no batch or file-size limit. Because everything runs in your browser, you can convert as many BMP files as you like, free and without signing up.
