Frequently Asked Questions
Why convert BMP to PNG?
BMP files are uncompressed and can be 2-10x larger than PNG. PNG uses lossless compression that preserves all pixel data while drastically reducing file size, making images faster to upload, share, and store.
Does PNG lose quality?
No. PNG uses lossless compression, meaning every pixel is preserved exactly. The visual quality is identical to the original BMP — only the file size is smaller.
What BMP formats are supported?
All standard BMP formats are supported: 1-bit, 4-bit, 8-bit, 16-bit, 24-bit, and 32-bit (with alpha channel). The conversion preserves color depth where possible.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser using the Canvas API. Your BMP file never leaves your device — 100% private and secure.
Can I convert multiple BMP files?
Currently the tool converts one file at a time. For batch conversion, use the Image Converter tool which supports multiple files with consistent output settings.
