What happens when you convert BMP to JPEG?
Lossy output
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.
BMP
Source
BMP
Windows Bitmap
Compression: Depends on variantTransparency: YesMetadata: DIB header, ICC (V5)
Windows raster storage with several DIB header versions. Simple uncompressed pixels are common, but alpha and compression vary.

JPEG
Joint Photographic Experts Group
Compression: LossyTransparency: NoMetadata: Exif, ICC
A familiar format for photographs. JPEG keeps files compact by trading a little image detail for broad compatibility.

Good choice when
- JPEG fits your delivery use: Photographs & sharing.
- An opaque image is acceptable for your destination.
- You accept lossy encoding for photographic delivery.
- You can validate the destination’s sample precision and colour interpretation.
Probably not when
- You need cutouts or translucent edges for compositing.
- You need an exact pixel reference or repeated lossless editing.
- You require identical samples without a defined colour and precision policy.
BMP to JPEG conversion details
- Opaque output
- Transparency is replaced with white by default. Change the background in Advanced options.
- Lossy output
- Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.
- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- BMP: Depends on variant → JPEG: Lossy BMP: BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. JPEG: Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Will JPEG preserve every decoded pixel?
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
