BMP is effectively uncompressed while PNG is lossless but compressed, so the file usually shrinks substantially and the pixels stay identical. There is rarely a reason to keep the BMP afterwards.
Flat colour and sharp text are exactly what PNG compresses best, and BMP screenshots are the most common source of needlessly huge image files.
If the BMP holds a photograph rather than a graphic, JPG will be far smaller than PNG at a quality nobody can distinguish.

Everything you need to know about bmp to png converter.
BMP and PNG are both lossless formats, but PNG uses DEFLATE compression to store pixel data efficiently. Converting BMP to PNG typically reduces file size by 50–75% with zero quality loss — every pixel is identical between the BMP source and the PNG output.
While BMP is a Windows-native format, PNG is universally supported across all platforms, web browsers, and applications. Converting your BMP files to PNG makes them compatible with macOS, Linux, web services, and mobile apps without any compatibility issues.
Use PNG when you need lossless quality, transparency support, or plan to edit the image. Use JPG for photographs where smaller file size is more important than pixel-perfect accuracy. BMP to PNG is the right choice when you want maximum compatibility with zero quality compromise.
Your image is sent over HTTPS to our conversion server and permanently deleted as soon as you download. We never store, index, or share your files.
