Upload any image file and instantly verify whether it is in BMP format. This tool works completely in your browser with no uploads to any server.
The Check If Image Is BMP tool allows users to quickly determine whether an image file is stored in BMP format. Instead of relying on file extensions, the tool reads the internal file signature to confirm the actual format.
All verification happens locally on your device, ensuring full privacy and complete security for your files.
BMP files can be identified by just two characters at the very beginning of the file: the letters "BM". This simple signature has been used for decades to recognize bitmap images on Windows systems.
The BMP image format, short for Bitmap, was introduced by Microsoft with the early versions of the Windows operating system. It became one of the first widely adopted digital image formats for personal computers.
Because BMP files store raw pixel data without compression, they are easy to analyze and validate. This tool uses that same simplicity to check the BMP file header directly in the browser, just like early desktop software once did.
