BMP (Bitmap) files are uncompressed and produce very large file sizes — a single BMP photo can be 10–30× larger than the same image as JPG or PNG. Converting BMP files is one of the most effective ways to reduce image file sizes. PixelForge handles BMP conversion instantly in your browser.
BMP (Bitmap Image File) is a raster graphics format developed by Microsoft for Windows. BMP files store pixel data with minimal or no compression, resulting in very large file sizes but perfect, lossless image quality. BMP is used in Windows system graphics, legacy applications, and situations where raw pixel access is needed. Most web and mobile platforms do not support BMP natively.
