Convert RAW to BMP — Free Online Converter

RAW to BMP converts unprocessed camera sensor data into a Windows Bitmap image file. Camera RAW files store the full 12-14 bit readout from the sensor's photosites, with no demosaicing, white balance, or compression applied. BMP is one of the simplest image formats — uncompressed pixel data with a minimal header. It stores every pixel's color values directly, making it the digital equivalent of a complete, unprocessed photograph.

Our converter uses Sharp to decode the RAW sensor data, apply demosaicing and tone mapping, then writes the result as a 24-bit or 32-bit BMP file.

BMP's simplicity is its strength. Many legacy Windows applications, embedded systems, industrial displays, and scientific imaging tools work exclusively with BMP files. The format requires no decoder beyond reading raw pixel values from a fixed offset — any software that can display pixels can display a BMP. Converting RAW to BMP gives you the full decoded image in the most universally parseable format possible.

Sharp reads the RAW file, applies Bayer demosaicing to reconstruct full RGB color from the sensor's color filter array, then applies white balance correction and gamma tone mapping. The resulting image is written as a BMP with a BITMAPINFOHEADER (40 bytes), followed by pixel data in BGR byte order (BMP convention). Standard output is 24-bit (8 bits per channel, no alpha). 32-bit BMP with alpha channel is available when transparency is needed. No compression is applied in the standard BMP output.
