How do I convert BMP to PNG?

Upload your BMP file above. It is converted to PNG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting BMP to PNG lose quality?

No. Both formats are lossless, so every pixel is kept exactly.

BMP or PNG: which should I use?

Use BMP for older Windows programs, embedded devices and tools that need raw pixels. Use PNG for screenshots, logos, text graphics and cut-outs. Keep in mind the main drawback of PNG: large files for photographs.

BMP gemmer pixels helt uden komprimering. Filerne er store, men meget gammel eller enkel software, der ikke kan læse moderne formater, kan som regel læse en BMP.

Is the BMP to PNG converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.
