// ABOUT BMP
BMP is an uncompressed raster format developed by Microsoft. It stores raw pixel data with no compression whatsoever, resulting in very large files but universal compatibility across Windows applications. BMP is most useful when a downstream tool or legacy application requires raw, uncompressed pixel data.
// ABOUT PNG
PNG uses lossless compression with full alpha-channel transparency support. It preserves every pixel exactly, making it the standard choice for screenshots, logos, web graphics, and any image where precision matters. PNG files tend to be larger than lossy alternatives but guarantee no quality degradation.
// WHY CONVERT
Converting BMP to PNG is useful when you need your image in a format suited for web graphics, screenshots, logos, icons, digital art, and images requiring transparency. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is BMP?
BMP is an uncompressed raster format native to Windows. Files are large because every pixel is stored without compression.
What is PNG?
PNG is a lossless compressed format that achieves smaller files than BMP without losing any pixel data. It supports transparency and is universally compatible.
Will converting BMP to PNG lose quality?
No. PNG is lossless. Every pixel from the BMP is preserved exactly in the PNG output, which will simply be smaller due to compression.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
