// 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 JPEG
JPEG uses lossy compression optimised for photographic content. It discards visual information the human eye is unlikely to notice, achieving compression ratios of 10:1 or higher with minimal perceptible quality loss. JPEG does not support transparency — any alpha channel is flattened against a white background.
// WHY CONVERT
Converting BMP to JPEG is useful when you need your image in a format suited for photographs, web images, email attachments, social media uploads, and any scenario where small file size matters more than pixel-perfect accuracy. 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 Windows format producing very large files. It is universally compatible but impractical for file sharing due to size.
What is JPEG?
JPEG is a lossy format optimised for photographs. It achieves high compression ratios that make images practical to share and store.
Will converting BMP to JPEG lose quality?
Yes. JPEG is lossy. At quality 80–90% the loss is usually imperceptible for photographs. Fine text and hard edges may show artifacts at lower settings.
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.
