Converting JPG to BMP decodes a compressed photo into the raw Windows bitmap that legacy desktop software and embedded systems read natively. Nothing about the picture changes, but the file grows sharply because BMP stores every pixel uncompressed.

Why convert JPG to BMP?
- Feed images to legacy Windows tools — old Visual Basic utilities, industrial HMIs, and label-printer software often accept only BMP.
- Prepare boot logos and splash screens for devices whose firmware can parse a BMP header but has no JPG decoder.
- Give image-processing code a dead-simple, predictable pixel layout to work against.
Tip: Budget for size: a 3 MB JPG photo becomes a 20-30 MB uncompressed 24-bit BMP, so convert single files, not whole photo libraries.
