QUICK ANSWER
Is it possible to convert JPG to BMP?
Yes - JPG converts to BMP.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Open the JPG in Windows Paint, choose File > Save as, and select BMP picture - no extra software needed. The main caveat is file size: BMP stores raw uncompressed pixels, so a 2 MB JPG can balloon to 20 MB or more as a BMP. No quality is recovered; any detail JPG already discarded is permanently gone.

Why convert JPG to BMP?

People convert JPG to .BMP mainly because older Windows software, industrial systems, or legacy workflows require raw bitmap input. It is also needed when an application expects pixel-exact data with no decompression overhead. Converting stops further quality loss but does not restore detail already removed by JPG compression.

How to convert JPG to BMP

Paint - Windows built-in BUILT-IN

Open the JPG in Paint, choose File > Save as, and select BMP picture.

Preview - macOS built-in BUILT-IN

Open the JPG in Preview, go to File > Export, and select BMP from the Format dropdown.

IrfanView FREE

Open the file, press S for Save as, and set the type to BMP; batch conversion is also supported via File > Batch Conversion.

GIMP OPEN-SOURCE

Open the JPG, go to File > Export As, and enter a filename ending in .bmp.

Command line - ImageMagick CLI

Run convert input.jpg output.bmp to convert in one step.

About these formats

.JPG JPEG Image

A JPG (also .jpeg) is a compressed photo or image in the JPEG format, standardized in 1992. Every operating system opens it natively - double-click and Windows Photos, macOS Preview, or…

Quality & what to watch

  • BMP stores raw uncompressed pixels, so file size increases dramatically - a 2 MB JPG can easily become 20 MB or more as a BMP.
  • No quality is recovered: any detail discarded by JPG compression is permanently gone; the BMP looks identical to the source JPG.
  • Exif metadata such as camera model, GPS coordinates, and capture date is not supported by BMP and will be lost in the conversion.

Frequently asked questions

Does converting JPG to BMP improve image quality?
No - the conversion only unpacks the compressed data; quality is exactly what the JPG contained, no better and no worse.
Why is the BMP file so much bigger than the JPG?
JPG uses lossy compression that typically shrinks file size by 10x or more; BMP stores raw pixel values with no compression, so the file size jumps back to width × height × 3 bytes for a 24-bit image.
Can I batch-convert multiple JPG files to BMP?
Yes - IrfanView's Batch Conversion (File > Batch Conversion/Rename) is the easiest option on Windows; on the command line, mogrify -format bmp *.jpg from ImageMagick handles it in one step.
Is BMP a good format for archiving photos?
Not particularly - PNG and TIFF are better lossless options; BMP is large and adds no benefit over those formats unless a specific application requires it.
