JPG to BMP — FAQ

Why convert JPG to BMP?+

BMP is required by legacy Windows software, some embedded systems, and hardware that can't handle JPEG. Convert to BMP when software specifically asks for it.

Will JPG compression artifacts appear in the BMP?+

Yes. JPG uses lossy compression, so any artifacts already in the JPG will be visible in the BMP. BMP is uncompressed, so it stores the pixels exactly as they appear in the JPG.

How much larger will the BMP be compared to my JPG?+

Typically 5–15× larger. A 500 KB JPG photo can produce a 5–10 MB BMP because BMP stores raw, uncompressed pixel data.

Are my files uploaded to a server?+

No. All conversion happens locally in your browser. Your JPG files are never sent to any server.

How large will the BMP file be compared to JPG?+

BMP is uncompressed, so it can be 10–20× larger than the equivalent JPG. A 200 KB JPG may become 2–3 MB as a 24-bit BMP. This is normal — use BMP only when legacy software specifically requires it.

Which programs can open BMP files?+

BMP files open natively in Microsoft Paint, Windows Photos, Adobe Photoshop, GIMP, and virtually any image viewer on Windows. On macOS, Preview opens BMP files. BMP is widely supported in legacy graphics, CAD, and embedded systems software where compatibility is critical.
