Does converting BMP to PNG lose quality?

No. PNG is lossless, so the result looks exactly like the BMP.

Can I convert many BMP files to PNG at once?

Yes. Drop as many BMP files as you like. They convert in parallel on your device and you can download them all as one ZIP.

Convert BMP images to PNG right in your browser. PNG is lossless and keeps transparency, ideal for screenshots, logos and graphics.

Format comparison

PNG compresses BMP losslessly, so you keep every pixel in a far smaller file.

	BMP	PNG
Compression	Uncompressed	Lossless
Transparency	No	Yes
Animation	No	No
Support	Most apps, rarely the web	Every browser and app
Best for	Legacy Windows software	Screenshots, logos and graphics

PNG is lossless, so every pixel of the BMP is kept. It's simply stored far more efficiently.
This is the best choice for scanned documents, screenshots and pixel art, where JPG would blur fine detail.
