What happens when you convert BMP to QOI?

Lossless sample storage

QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Sample precision & colour

Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

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.

Is BMP → QOI right for you?

Good choice when

  • QOI fits your delivery use: Application assets & simple decoding.
  • You need a transparency-capable destination and will check its supported variant.
  • You need lossless storage of the rendered samples supported by QOI.
  • 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 expect lossless encoding to restore lost details or editing structure.
  • You require identical samples without a defined colour and precision policy.

BMP to QOI conversion details

Transparency representation
The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
Lossless sample storage
QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
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 → QOI: Lossless 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. QOI: QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee.
Transparency
Transparency is replaced with white by default. Change the background in Advanced options.
Colour depth
BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp → QOI: 8 bits/sample
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

Does lossless output mean an unchanged source?

QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Are bit depth and colour values guaranteed to match?

Will metadata and colour profiles be retained?
