What is a .PDN file?
PDN is the native layered format of Paint.NET, a free Windows image editor. Created and opened by Paint.NET.
- Did you know
- Paint.NET began in 2004 as a university project meant to better Microsoft Paint.
- Paint.NET is written in C# on Microsoft’s .NET platform, and a PDN preserves its layers and transparency.
- The PDN file is a compressed dump of the editor’s internal document object rather than a generic image format.
- What Analyser reads
- Identify design-app files: Figma (FIG), Sketch, Affinity Photo/Designer/Publisher, Procreate, GIMP (XCF), Krita (KRA), Paint.NET, and Substance.
- Depth of analysis
- .PDN is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .PDN file
- Drag a .PDN file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
