Convert BMP to WEBP
About BMP
The Bitmap (BMP) file format is a simple, uncompressed raster graphics format developed by Microsoft for the Windows operating system. Because it's typically uncompressed, BMP files store raw pixel data, resulting in very large file sizes. While this ensures maximum quality, its inefficiency makes it impractical for web use or easy sharing. It's now largely a legacy format.
About WEBP
WebP is a modern image format developed by Google to provide superior lossless and lossy compression for images on the web. WebP images are significantly smaller than their JPEG and PNG equivalents, which helps websites load faster and save bandwidth. It also supports transparency and animation, making it a versatile replacement for both JPEG, PNG, and GIF.

Frequently Asked Questions
Is there any reason to use BMP today?
In modern workflows, there are very few reasons to use BMP. Its primary advantage was its simplicity and wide support in early Windows applications. For almost any purpose, formats like PNG (for lossless quality) or TIFF (for professional work) are far superior choices.
Does BMP support compression?
While the BMP format does support a simple lossless compression method called Run-Length Encoding (RLE), it is rarely used and not very effective. The vast majority of BMP files you encounter will be uncompressed.
Is WebP supported everywhere?
WebP is now supported by all major modern browsers, including Chrome, Firefox, Safari (version 14 and later), and Edge. While its adoption is widespread, some very old browsers or simple image viewers may not support it, so providing a fallback to JPEG or PNG is sometimes necessary.
How much smaller is WebP compared to JPEG?
According to Google's data, lossy WebP images are typically 25-34% smaller than comparable JPEG images at the same quality index. Lossless WebP images are about 26% smaller than PNGs.
