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 a PNG file?

Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression, created as a patent-free replacement for the Graphics Interchange Format (GIF). Standardized as ISO/IEC 15948:2004, PNG utilizes the DEFLATE compression algorithm (a combination of LZ77 and Huffman coding) and supports palette-based images, grayscale, and full-color non-palette-based RGB/RGBA images. A defining feature is its alpha channel support, allowing for variable transparency levels, unlike the binary transparency of GIF. It does not support animation but offers gamma correction and interlacing via the Adam7 algorithm.

How to open a PNG file

PNG files possess near-universal compatibility across all major operating systems (Windows, macOS, Linux, Android, iOS) and web browsers (Chrome, Firefox, Safari) without requiring additional software. Default image viewers such as Microsoft Photos, Apple Preview, and virtually all graphics editing software including GIMP, Adobe Photoshop, and Paint.NET natively handle the format.
