About BMP to PNG converter
BMP is an outdated raster image format that stores every pixel without compression. Files turn out very large. PNG is a modern format that also supports lossless compression, but weighs significantly less. Quality stays perfect — not a single pixel is lost.
Our converter transforms BMP to PNG right in your browser. The file is not sent to the server — all processing happens on your device. This means your images stay private and no one but you has access to them.
Why use this converter
- Lossless: PNG saves every pixel without lossy compression.
- Smaller size: PNG weighs several times less than BMP at the same quality.
- Privacy: files are not uploaded to server and not stored anywhere.
- Free: no registration, no limits on file count.
- Universal: works in Chrome, Firefox, Edge on Windows, Mac, Linux, Android and iOS.
How to use

Frequently asked questions
Where do my files go? Nowhere. The file is processed in your browser's memory and disappears when you close the page.
Why doesn't it work in Safari? Safari doesn't support BMP decoding. Use Chrome, Firefox or Edge.
Is quality lost? No. PNG is a lossless format, every pixel is saved exactly.
What about transparency? BMP doesn't support transparency, so the background stays non-transparent.
