BMP Image Converter & Editor
BMP (Bitmap) is a raw, uncompressed image format that preserves every pixel exactly as captured. While this makes BMP lossless, it also makes files enormous. A single 1920x1080 image is over 6 MB. FastEdit converts BMP to modern compressed formats like PNG, WebP, AVIF, or JPEG instantly in your browser.
BMP files commonly appear in legacy systems, medical imaging, industrial applications, and Windows clipboard operations. FastEdit lets you convert and optimize them without installing specialized software or uploading sensitive data.
