Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.

What happens when you convert JPEG to BMP?
Encoding mode
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. The output uses the implemented still-image encoder; file size depends on the pixels and format.

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.

Target
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.

Good choice when
- BMP fits your delivery use: Windows bitmap interchange.
- Your receiving application supports the required BMP variant.
- You can validate the destination’s sample precision and colour interpretation.
- You need a BMP-compatible workflow that can hold transparency added in a separate edit.
Probably not when
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
- You require identical samples without a defined colour and precision policy.
- You expect automatic background removal or transparency.
JPEG to BMP conversion details
- Transparency
- The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
- Encoding mode
- 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. The output uses the implemented still-image encoder; file size depends on the pixels and format.
- 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
- JPEG: Lossy → BMP: Depends on variant JPEG: Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. 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.
- 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.
Common questions
Will the background become transparent?
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Which compression mode will BMP use?
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. The output uses the implemented still-image encoder; file size depends on the pixels and format.
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.
