DNG to GIF: conversion guide

What happens when you convert DNG to GIF?

RAW development

DNG needs camera- and file-aware development to produce a rendered GIF image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.

GIF palette & alpha limits

GIF uses at most 256 colours per GIF colour table and a transparent palette index rather than partial alpha. Richer colours and translucent edges need quantisation or compositing. Palette choice and dithering depend on the future engine; lossless GIF compression does not reverse palette reduction.

Is DNG → GIF right for you?

Good choice when

GIF fits your delivery use: Simple palette animations.
You need a developed image for a non-RAW application.
A limited palette and binary transparency are acceptable.
You can validate the destination’s sample precision and colour interpretation.

Probably not when

You need the original sensor data and freedom to redevelop it.
You need smooth photographic gradients or partial transparency.
You require identical samples without a defined colour and precision policy.

DNG to GIF conversion details

RAW development: DNG needs camera- and file-aware development to produce a rendered GIF image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.
GIF palette & alpha limits: GIF uses at most 256 colours per GIF colour table and a transparent palette index rather than partial alpha. Richer colours and translucent edges need quantisation or compositing. Palette choice and dithering depend on the future engine; lossless GIF compression does not reverse palette reduction.
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: DNG: Depends on variant → GIF: Lossless DNG: Compression, sample type and processing stage are defined by the file and DNG version. Converting a proprietary raw file to DNG is different from exporting a rendered photo, but it does not guarantee preservation of every maker-specific feature. Keep the source when future reprocessing or vendor software matters. GIF: LZW compression is lossless for the stored palette indices. Colour reduction before encoding is not lossless for an arbitrary RGB source.
Transparency: DNG: No → GIF: Yes
Animation: DNG: No → GIF: Yes
Colour depth: DNG: File-defined sample precision → GIF: Up to 256 colours/table
Sensor data: DNG: Raw development required
Dimensions: Pixel dimensions, page geometry, rendering resolution, resizing and orientation need explicit converter policies. The future engine has not defined them yet.
Metadata: DNG: Exif, DNG tags → GIF: Comments, Application extensions. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.

Common questions

Will GIF still be an editable camera RAW?

DNG needs camera- and file-aware development to produce a rendered GIF image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.

Why can GIF lose colours despite lossless compression?

GIF uses at most 256 colours per GIF colour table and a transparent palette index rather than partial alpha. Richer colours and translucent edges need quantisation or compositing. Palette choice and dithering depend on the future engine; lossless GIF compression does not reverse palette reduction.

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?

DNG: Exif, DNG tags → GIF: Comments, Application extensions. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
