Frequently asked questions
No. Conversion runs in your browser via WebAssembly. Your files never leave your device.
Almost no one should — unless forced to. Specific cases: older Windows applications that only accept BMP input, game modding tools and level editors that require uncompressed textures, industrial machine vision or embedded display drivers with BMP-only APIs, and some legacy print workflows. If your software accepts PNG, use PNG.
BMP is uncompressed by default — every pixel's RGB value is stored directly. PNG uses lossless compression that can reduce file size by 50–80%. A 1920×1080 24-bit BMP is always about 6MB regardless of image content.
Standard 24-bit BMP does not support an alpha channel. 32-bit BMP technically can, but it is not widely supported by applications that read BMP. If your target application needs transparency, keep using PNG.
