// 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.
// 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.
// WHY CONVERT
Converting PNG to BMP is useful when you need your image in a format suited for legacy Windows applications, game engines requiring uncompressed textures, hardware tools, and scenarios where decompression overhead must be zero. Since BMP stores raw pixel data, the resulting file will be significantly larger than the PNG source, but no quality is lost. 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 PNG?
PNG is a lossless compressed image format with transparency support, widely used for web graphics and screenshots.
What is BMP?
BMP (Bitmap) is an uncompressed raster format. Files are large because no compression is applied, but the format is universally supported on Windows and compatible with many legacy applications.
Will converting PNG to BMP lose quality?
No. BMP stores raw pixel data, so no quality is lost compared to the PNG source. The resulting file will simply be larger due to the lack of 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.
