Frequently Asked Questions

Why are BMP files so large?

BMP is an uncompressed format that stores every pixel without compression. A 1920x1080 image will be approximately 6MB regardless of content, while PNG compresses based on image complexity.

Does BMP support transparency?

Standard BMP does not support transparency. Transparent areas in your PNG will be converted to a solid background color (typically white or black).

When would I need to use BMP format?

BMP is mainly needed for compatibility with older Windows software, legacy systems, or specific applications that require uncompressed bitmap format. For modern use, PNG or JPG are better choices.

Can I convert BMP back to PNG?

Yes! Converting BMP to PNG will compress the file and significantly reduce file size without any quality loss, since BMP is uncompressed.
