What is a DNG file?

The DNG (Digital Negative) format is a royalty-free, open standard raw image container developed by Adobe Systems to address the fragmentation of proprietary raw formats. It is based on the TIFF/EP standard (ISO 12234-2) and supports linear raw data, uncompressed sensor data, or losslessly compressed JPEG streams. DNG files embed XMP (Extensible Metadata Platform) metadata directly within the file header, eliminating the need for sidecar files. It serves as an archival format and is natively utilized by Leica, Hasselblad, and Pentax cameras.

How to open a DNG file

DNG files benefit from broad native support across operating systems; macOS Preview and Microsoft Photos (with the Raw Image Extension) can render them directly. For professional editing, Adobe Photoshop, Lightroom, and Capture One provide full support. The format's open architecture also allows for seamless viewing in non-Adobe applications like Google Photos and various open-source Linux editors such as Darktable.

What is an AVIF file?

The AVIF (AV1 Image File Format) is an open, royalty-free raster image container specified by the Alliance for Open Media (AOMedia) in ISO/IEC 23000-12. It encapsulates image sequences or still images compressed with the AV1 video codec within the HEIF (High Efficiency Image File Format) container structure. AVIF supports high dynamic range (HDR) utilizing Perceptual Quantizer (PQ) or Hybrid Log-Gamma (HLG) transfer functions, wide color gamut (WCG), and 4:2:0, 4:2:2, or 4:4:4 chroma subsampling, offering superior compression efficiency over JPEG and WebP.

How to open an AVIF file

Native support for AVIF is available in modern web browsers including Google Chrome (v85+), Mozilla Firefox (v93+), and Safari (v16+). For local viewing, Windows 10 and 11 require the installation of the free 'AV1 Video Extension' from the Microsoft Store to enable support in the Photos app and File Explorer. macOS 13 (Ventura) and iOS 16 provide system-level support. Graphics editors like GIMP, Paint.NET, and Adobe Photoshop (via plugin) can also decode and edit these files.
