What Paint.NET does
Paint.NET is a free image and photo editing application for Windows, developed and maintained by dotPDN LLC. It was originally created as a student project intended to be a more capable alternative to the Microsoft Paint application that ships with Windows, and has since grown into a mature editor that many users treat as their primary graphics tool. The editor is built around a layered canvas model, where images can be composed from multiple independent layers, each with its own opacity setting and blend mode. A full undo history lets users step backwards through every edit made in a session. The tool palette covers the typical needs of photo retouching and graphics work: crop, resize, rotate, selection tools of various shapes, a clone stamp, a gradient fill, text rendering, and a set of drawing tools. Built-in adjustment controls include brightness and contrast, curves, levels, hue and saturation, and color balance. A separate effects menu offers sharpening, blur variants, emboss, noise reduction, distortions, and other processing operations. Rendering is hardware-accelerated, keeping the interface responsive even on large images. Paint.NET supports a range of common image formats for opening and saving, including PNG, JPEG, BMP, GIF, TIFF, and its own layered PDN format. A community of plugin developers has produced a large library of additional effects and format handlers that can be installed to extend the application. The application targets Windows users who need more editing capability than the built-in Paint app provides but prefer a lighter, faster tool compared to professional-grade suites. It is well suited to everyday tasks such as photo cropping and color correction, creating simple graphics, annotating screenshots, and compositing layered images.
