JPG to BMP Converter
Convert JPEG files (released 1992, Lossy) to BMP (None (uncompressed) or RLE, typically Very large — pixel-by-pixel storage). Runs in your browser — no upload, no signup.
Based on 12,431+ conversions delivered
Need to turn JPG files into BMP? This tool does it in seconds, right in your browser. JPEG is known for Photographs, hero images, anything where small file matters more than transparency and BMP for Legacy Windows tools, embedded devices, industrial scanners, so the conversion makes sense whenever your workflow has standardised on BMP or your target platform expects it. In our sample set, BMP files ran about 511% larger than the JPG source. There's no software to install and nothing is sent to a server — the fast path encodes locally and hands you the file immediately. Read on for a plain-language comparison of JPEG and BMP, the settings that matter, the pitfalls to avoid, and answers to the questions people ask most about JPG → BMP.

Heads up before converting JPG → BMP
What changes — and what your conversion will cost — based on how JPEG and BMP differ.
Embedded color profile gets dropped
JPEG can carry an embedded ICC color profile; BMP doesn't preserve one. Colour-managed pipelines (proofing, brand-accurate print, wide-gamut displays) interpret the missing profile as sRGB, which shifts hues on anything captured in Display P3 or Adobe RGB. If the colour math matters, convert the image to sRGB explicitly before exporting to BMP.
Best practices for JPG → BMP
Concrete settings to pick before you convert JPEG to BMP.
- Always preview the BMP output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- BMP is lossless, so quality settings don't apply — but you can still shave bytes by quantising the palette (pngquant for PNG, gif2webp for GIF) when the image has a limited colour count.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to BMP.
- For web BMP delivery, encode in sRGB — wider colour spaces (Display P3, ProPhoto) render unpredictably across browsers and email clients.
- Converting to BMP silently drops EXIF/XMP metadata embedded in the source. That's a privacy win if the file is being shared, but a loss if you rely on capture date, GPS, or camera settings — copy what you need to a sidecar before converting.
When NOT to convert JPG → BMP
Honest cases where this conversion is the wrong call — pick a different format or keep your JPEG source.
Skip if the file is bound for print
BMP is a delivery-grade web format. Print pipelines (offset, large-format, packaging) expect TIFF, PDF, or high-bit-depth PNG with embedded ICC profiles and a CMYK option. Converting JPEG to BMP for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
