How do I convert PNG to BMP?

Upload your PNG file above. It is converted to BMP 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 PNG to BMP lose quality?

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

Will the BMP keep the transparent background?

No. BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

PNG stores every pixel exactly and supports smooth transparency, which makes it the go-to format for screenshots, logos and graphics, at the cost of large files for photos.

Is the PNG to BMP 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.
