PDN to RLA Conversion: FAQ

What are PDN files?

PDN is the native file format used by Paint.NET, a popular free image and photo editing software for Windows. A PDN file stores the entire project data for an image, including layers, layer properties, transparency, blending modes, text, and editing history. Unlike standard image formats like JPEG or PNG, which flatten an image into a single layer, PDN files preserve all editable elements, making them ideal for ongoing design work or complex image editing tasks.

What are RLA files?

The RLA image format, whose name stands for Run-Length Encoded Version A, is associated with the animation package Wavefront Advanced Visualizer. RLAs are output files storing 3D data and used for exchanging graphical data with other applications.
