JPG

JPG Joint Photographic Experts Group

JPG (also written JPEG) is the most widely supported photo format. Its lossy compression discards detail the eye is less sensitive to, which makes photos small enough for email, upload forms and print services that accept nothing else.

BMP

BMP Windows Bitmap

BMP is the uncompressed bitmap format native to Windows. Files are large because each pixel is stored raw, but almost every program, embedded device and legacy system can read it.

Why convert JPG to BMP?

JPG is what most cameras, websites and phones set to Most Compatible hand you, so it is the usual starting point for photos. It cannot store transparency and every re-save loses a little more detail. Choose BMP only when a legacy program or device needs uncompressed bitmaps.

You can also cap the width and height, which resizes large photos in the same step.

Frequently asked questions

Will the BMP lose quality?

BMP is lossless, so the conversion keeps every pixel or sample that is in your JPG file. It cannot bring back detail that JPG compression already removed, and the BMP file will usually be larger.

Will the BMP be smaller than the JPG?

No, usually larger for photos: as a rough guide, the BMP comes out at around 30× the size of the JPG, depending on the quality setting.
