What happens when you convert TIFF to QOI?

Multiple source images

One page is converted (default: page 1). Choose another page in Advanced options.

HDR to SDR

HDR is rendered to SDR using exposure and Reinhard tone mapping.

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.

8-bit destination samples

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

Is TIFF → QOI right for you?

Good choice when

QOI fits your delivery use: Application assets & simple decoding.
You can choose the source image or part needed for delivery.
You need an SDR delivery copy and can review its tone mapping.
You need a transparency-capable destination and will check its supported variant.

Probably not when

You require a complete collection, page set or multipart round trip.
You need the original HDR range for relighting or grading.
You assume format-level alpha support guarantees matching transparent edges.
You expect lossless encoding to restore lost details or editing structure.

Conversion considerations

TIFF can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.
If HDR source content is exported through an SDR representation, it needs a display rendering. Values outside the output range require tone mapping, scaling or clipping; brightness relationships can change. Tone mapping, exposure and colour handling depend on the future engine. Renaming or lossless compression cannot preserve out-of-range values.
The reviewed QOI representation uses 8-bit colour samples. If the source contains higher-precision samples, they must be reduced before encoding, even in a lossless output mode. Rounding, dithering and colour conversion are future engine decisions; lost precision cannot be recovered from this output.

HDR to SDR: HDR is rendered to SDR using exposure and Reinhard tone mapping.
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.
8-bit destination samples: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
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: TIFF: Depends on variant → QOI: Lossless TIFF: TIFF is not intrinsically lossless or uncompressed. Read the Compression, BitsPerSample and SampleFormat tags; decoder support varies across schemes. 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: TIFF: Tagged sample types → QOI: 8 bits/sample
Multiple images: TIFF: Image directories
Dimensions: One page is converted (default: page 1). Choose another page in Advanced options.
Metadata: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Common questions

Will every source image be exported?

One page is converted (default: page 1). Choose another page in Advanced options.

How will HDR brightness be mapped?

HDR is rendered to SDR using exposure and Reinhard tone mapping.

Does lossless output mean an unchanged source?

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.
