BMP to PNG Converter
Convert BMP bitmap files into lossless PNG images in your browser. PNG keeps every pixel exactly, but stores it far more efficiently than an uncompressed BMP.

Converts to PNG. Files stay on your device — nothing is uploaded.
Lossless, but much smaller than BMP
PNG uses lossless compression, so the converted image is pixel-for-pixel identical to your BMP — nothing is thrown away. It simply stores the image far more efficiently, so the file is dramatically smaller.
Choose PNG over JPG when you need a perfect, lossless copy — for example for line art, screenshots, or images with sharp edges and text.
Private, in-browser conversion
Your BMP files are converted to PNG right on your device, with no uploads and no limits on how many you process.
Frequently asked questions
Does converting to PNG lose any quality?
No. PNG is lossless, so the result is identical to the original BMP, just stored more efficiently.
Should I choose PNG or JPG?
Choose PNG for a perfect lossless copy (best for text, screenshots and graphics). Choose JPG for the smallest possible file when a tiny, invisible quality loss is acceptable.
