JPEG to BMP Conversion

JPEG files use lossy compression, which means they sacrifice some image quality to achieve smaller file sizes. Every time you edit and save a JPEG, it loses a bit more quality. JPEGs also don't support transparency, so every pixel must have a color value.

BMP (Bitmap) is an uncompressed raster image format. It stores color data for every pixel without any compression, resulting in very large file sizes. While it offers high quality, its large size makes it impractical for web use.

Frequently Asked Questions

Why should you convert JPEG to BMP?

JPEG's lossy compression permanently alters pixel values through quantization and DCT rounding errors - the decompressed image mathematically differs from the original at the bit level. This is acceptable for viewing but problematic for pixel-level analysis, legacy DOS/Windows 3.x applications that predate JPEG support, or scientific imaging where exact pixel values matter (though note: JPEG already degraded quality, BMP just preserves that degraded state). Converting to BMP creates an uncompressed raster with zero additional processing but cannot recover information JPEG already discarded. File sizes explode dramatically - a 200KB JPEG becomes 6-30MB as BMP depending on resolution. Use cases include importing into vintage software requiring BMP (old games, Windows 95-era programs), certain medical imaging systems with strict format requirements, or preventing further compression in archival workflows - though TIFF or PNG are better modern alternatives for lossless storage.
