Frequently Asked Questions
Why convert BMP to PNG?↓
BMP files are uncompressed and very large. Converting to PNG reduces file size significantly through lossless compression while maintaining identical visual quality.
How much smaller will my PNG be compared to BMP?↓
PNG files are typically 60-80% smaller than BMP for the same image. Compression ratio depends on image content — solid colors compress more than photos.
Does BMP to PNG conversion lose quality?↓
No. Both BMP and PNG store pixel data losslessly. Converting between them is a lossless operation with zero quality loss guaranteed.
What is BMP format used for?↓
BMP is a legacy Windows format that stores raw uncompressed pixel data. It is mainly used in legacy applications. PNG is a better modern alternative.
