BMP to PNG Conversion Guide
Conversion Process Explained
When converting BMP files to PNG format, these technical transformations occur:
- Compression applied: From BMP's uncompressed format to PNG's lossless DEFLATE compression
- File size reduction: Typically 30-70% smaller than original BMP files
- Quality preservation: PNG maintains identical visual quality to the original BMP
- Transparency support: Option to add alpha channel transparency (not present in BMP)
- Metadata handling: Preserves important image metadata during conversion
Privacy Protection: All conversions happen directly in your browser - your images never leave your device.
