Frequently Asked Questions

Why convert BMP to PNG?

PNG is lossless like BMP but uses compression — typically 70–90% smaller files. PNG is also the standard format for web and modern software.

Will my screenshots look identical?

Yes — pixel-perfect identical. PNG uses lossless compression, so no pixel data changes.

What about indexed-color BMPs?

Supported. 1-bit, 4-bit, and 8-bit palette BMPs convert to indexed-color PNGs preserving the original palette.
