JPG to BMP Converter Features
Uncompressed Output
BMP is an uncompressed image format. Our converter strips away the JPG compression wrapper, providing you with exact raw pixel data.
Fixes EXIF Rotation
Images taken from mobile phones often load sideways. Our tool automatically reads EXIF orientation data and ensures your final BMP is perfectly upright.
100% Private
Your photos never touch the internet. The entire JPG to BMP conversion process happens locally on your own computer or smartphone.
Frequently Asked Questions
Converting is incredibly simple. Just drag and drop your JPG or JPEG image into the upload box on this page. Our tool will automatically decode the compressed image and provide a downloadable BMP file instantly.
Yes, almost certainly. JPG utilizes a highly efficient "lossy" compression algorithm to achieve small file sizes. BMP (Bitmap) files are completely uncompressed, storing raw color data for every single pixel. Converting a JPG to a BMP will result in a much larger file.
No. Converting from JPG to BMP will not restore any quality or detail that was already lost when the image was originally compressed and saved as a JPG. The resulting BMP will simply be an exact, uncompressed visual replica of the source JPG.
Standard BMP formats typically do not support alpha channels (transparency), and JPG formats certainly do not. If you are converting a standard JPG, there is no transparency to worry about, and the resulting BMP will retain the same solid background.
While JPG is great for sharing photos due to its small size, BMP is often required for legacy Windows applications, specific industrial hardware, older game engines, or scenarios where an uncompressed pixel-map is specifically requested by software.
It is perfectly safe because nothing is actually uploaded to our servers! This tool leverages modern HTML5 technology to convert the image entirely inside your own web browser. Your files never leave your device.
