Convert BMP to PNG

BMP files from old software, scanners and Windows Paint are large and often rejected by websites. Convert them to PNG: the same pixels, losslessly compressed and much smaller, accepted everywhere. Batch conversion runs in your browser.

Frequently asked questions

Why convert BMP to PNG?

BMP files are usually uncompressed, so they're huge, and many websites won't accept them. PNG keeps every pixel but compresses losslessly, often to a fraction of the size.

Does BMP to PNG lose any quality?

No. PNG is lossless, so the image is pixel-for-pixel identical to the BMP.

Should I convert BMP to PNG or JPG?

PNG for screenshots, diagrams and graphics with text; JPG for photos when you need the smallest file and can accept slight compression.
