BMP and WebP explained
What is a BMP file?
BMP (Bitmap) is an uncompressed raster image format developed by Microsoft. It stores pixel data with no quality loss, which produces large but perfectly accurate files.
What is a WebP file?
WebP is a modern image format from Google that delivers superior compression for both lossy and lossless images. WebP files are typically 25 to 35 percent smaller than equivalent JPG or PNG files.
Convert BMP to WebP on any device
You can convert BMP to WebP on Windows, Mac, Linux, Chromebook, Android and iPhone, straight from Chrome, Safari, Edge or Firefox. There is no app to install and no account to create. Because the conversion runs on your own device, it also works offline once the page has loaded, and you can convert as many files as you want.
