// 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 WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, as well as transparency and animation. Lossless WebP files are typically 25–35% smaller than equivalent PNGs, while lossy WebP achieves similar quality to JPEG at 25–34% smaller file sizes. All major browsers have supported WebP since 2020.
// WHY CONVERT
Converting BMP to WebP is useful when you need your image in a format suited for web optimisation, responsive images, progressive web apps, and any context where smaller files improve page load times. 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. Files are very large because no compression is applied to the pixel data.
What is WebP?
WebP is a modern format by Google offering both lossless and lossy compression with significantly smaller files than BMP, PNG, or JPEG.
Will converting BMP to WebP lose quality?
Not with lossless WebP, which preserves every pixel exactly. With lossy WebP there is some compression artifact, but file sizes are dramatically smaller.
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.
