What happens when you convert BMP to HEIF?

Encoding mode

HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading. HEIF permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.

Sample precision & colour

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.

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.

An image container for individual pictures, collections and sequences. The codec inside determines compression.

Is BMP → HEIF right for you?

Good choice when

  • HEIF fits your delivery use: Device photography & image collections.
  • You need a transparency-capable destination and will check its supported variant.
  • Your receiving application supports the required HEIF variant.
  • You can validate the destination’s sample precision and colour interpretation.

Probably not when

  • You assume format-level alpha support guarantees matching transparent edges.
  • You need a guaranteed quality or file size before encoder settings exist.
  • You require identical samples without a defined colour and precision policy.

BMP to HEIF conversion details

Transparency representation
Both format profiles allow transparency, but this does not promise identical alpha representation. Source variants, target channel precision and alpha interpretation matter. The future encoder must explicitly carry or convert transparency; merely choosing HEIF guarantees no alpha transfer.
Encoding mode
HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading. HEIF permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.
Sample precision & colour
Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
Metadata & colour
Format support does not guarantee that an export preserves metadata or colour profiles. Retention and colour handling depend on the future converter; its engine is not implemented yet.
Compression
BMP: Depends on variant → HEIF: Depends on variant 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. HEIF: HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading.
Transparency
BMP: Yes → HEIF: Yes
Animation
BMP: No → HEIF: Yes
Colour depth
BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp → HEIF: Codec/profile dependent
HDR
HEIF: Codec/profile dependent
Multiple images
HEIF: Collections & sequences
Dimensions
Pixel dimensions, page geometry, rendering resolution, resizing and orientation need explicit converter policies. The future engine has not defined them yet.
Metadata
BMP: DIB header, ICC (V5) → HEIF: Exif, XMP, ICC, NCLX. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.

Common questions

Which compression mode will HEIF use?

HEIF defines the container. Compression may be lossy, lossless or uncompressed depending on its codec binding; one global quality or bit-depth value would be misleading. HEIF permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.

Are bit depth and colour values guaranteed to match?

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.

Will metadata and colour profiles be retained?

BMP: DIB header, ICC (V5) → HEIF: Exif, XMP, ICC, NCLX. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
