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 shows you
- Open Krita (.kra), Procreate and Paint.NET (.pdn) paintings by showing the flattened preview baked into the file - the full merged image for Krita, the QuickLook thumbnail for Procreate, the embedded PNG preview for Paint.NET - alongside the canvas size, layer count and app version. Their per-layer artwork is in a private format, so the embedded preview is the faithful render.
- Open a .PDN file
- Drag a .PDN file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
