Paint.NET (sometimes stylized as paint.net) is a freeware general-purpose raster graphics editor program for Microsoft Windows, developed with the .NET platform. Paint.NET originated as a computer science senior design project by Rick Brewster during spring 2004 at Washington State University. Version 1.0 consisted of 36,000 lines of code and was written in four months. In contrast, version 3.35 has approximately 162,000 lines of code. Development continued with one programmer who worked on previous versions of Paint.NET while he was a student at WSU.
Paint.NET is primarily programmed in the C# programming language. Paint.NET supports plugins, which add image adjustments, effects, and support for additional file types. They can be programmed using any .NET Framework programming language, though they are most commonly written in C#. These are created by volunteer coders on the program's discussion board, the Paint.NET Forum. Though most are simply published via the discussion board, some have been included with a later release of the program. Hundreds of plugins have been produced; such as Shape3D, which renders a 2D drawing into a 3D shape.
Paint.NET was created exclusively for Windows and has no native support for other operating systems. Due to its former open-source licensing, the development of alternative versions was possible. In May 2007, Miguel de Icaza officially started a porting project called paint-mono. This project had partially ported Paint.NET 3.0 to Mono, an open-source implementation of the Common Language Infrastructure on which the .NET Framework is based. This allowed Paint.NET to be run on Mono-supported platforms, such as Linux. In 2010, developer Jonathan Pobst started a project called Pinta, describing it as a clone of Paint.NET for Mono and Gtk#.
Starting with version 4.0.18, Paint.NET is published in two editions: A classic edition remains freeware, similar to all other versions since 3.5. Another edition, however, is published to Microsoft Store under a trialware license and is available to purchase for US$14.99. In May 2026, Brewster revealed that he obtained the paint.net domain after attempting to do so for 22 years. Historically, the editor was hosted on getpaint.net, and according to Brewster, the previous owners of paint.net would not sell the domain and asked for "lots and lots of money". In December of the previous year, paint.net began hosting content that impersonated Paint.NET, therefore becoming a clear case of trademark infringement and domain squatting.
Paint.NET is known for its intuitive interface, strong performance, and a robust plugin ecosystem. The program’s plugins add a wide array of image adjustments, effects, and support for additional file types, expanding its native capabilities beyond the core toolset. It remains a Windows-centric solution, with non-native options such as Mono-based ports and clones arising in the ecosystem, but no official Android edition exists from the original developers.
For Android users seeking a Paint.NET-like experience, several realities shape choices: Android does not officially host Paint.NET, so native Android equivalents emphasize basic Windows-like tools (rectangle select, copy/paste, text, layers) plus performance on mobile hardware. Apps described as “MS Paint-like” or “Paint.NET-inspired” on Android often prioritize touch-friendly workflows, on-device editing speed, and simplified layer management. Some options may offer PDF-to-image editing workflows or integration with online editors, though these are not direct Paint.NET ports.
Android-friendly alternatives and how they compare
Basic tools on Android that resemble Paint.NET include rectangle selection, copy/paste, text addition, and layers support as a nice-to-have feature. Some editors provide these capabilities with varying levels of polish. While Paint.NET itself does not run on Android, enthusiasts often look for software that mimics its core workflow: a straightforward interface, a familiar set of raster-editing tools, and support for common image formats.
When editing PDFs converted to images on Android, apps like WPS Office can convert PDFs to images and provide basic editing options. Xodo Premium is frequently cited for its competent feature set in PDF manipulation, though there are other contenders as well. For image editing in a broader sense, some Android apps aim to deliver a Paint.NET-inspired experience with essential tools and layer management, while others emphasize online collaboration or cloud integration.
On the topic of cross-platform efforts inspired by Paint.NET, the history of Mono-based ports and clones illustrates how a Windows-focused program can influence alternative environments. Paint-mono and Pinta represent efforts to bring similar concepts to Linux and Mono-supported platforms, highlighting the challenges of porting a Windows desktop app to Android without official support from the original developers.
What to expect from a Paint.NET-inspired Android app
- Basic raster editing with a familiar toolset: selection, move, text, brush, and eraser.
- Layer support to manage edits non-destructively.
- Plugin-style extendability is often limited on Android but some apps offer filters or effects.
- Performance optimized for mobile hardware, with intuitive touch controls and compact interfaces.
In practice, users seeking a faithful Paint.NET experience on Android may need to rely on a combination of apps or rely on remote desktop solutions to access a Windows environment that runs Paint.NET. The Android ecosystem does not include an official Paint.NET release, and as such, any Android workflow will be an approximation rather than a direct port.
For those who value a true Windows-grade editor on Android, the most reliable path remains using Windows on device via virtualization or remote access, or sticking to Android-native editors that capture the essence of Paint.NET’s workflow rather than its exact implementation.

In summary, Paint.NET remains a landmark Windows application with a strong plugin ecosystem and a long development history. Its core design choices-clear toolsets, layered editing, and extensibility-continue to influence discussions about cross-platform image editing on Android, even though a native Android version does not exist as of now.
