Paint.NET is an open source, raster graphics editing program for Windows, developed on the .NET Framework. Paint.NET has evolved from a simple replacement for the Microsoft Paint program, which is included with Windows, into a powerful editor with support for layers, blending, transparency, and plugins.
Paint.NET has many of the powerful features that expensive commercial applications have, including the ability to use layers.
Features of Paint.NET:
- Simple, intuitive, and innovative user interface. Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance.
- Layers. Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience.
- Frequently Updated. Updates usually come about every 4 to 6 weeks, and contain new features, performance improvements, and bug fixes.
- Special Effects. Many special effects are included for enhancing and perfecting your images. Everything from blurring, sharpening, red-eye removal, distortion, noise, and embossing are included. Also included is our unique 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.
- Adjustments are also included which help you tweak an image's brightness, contrast, hue, saturation, curves, and levels.
- Powerful Tools. Paint.NET includes simple tools for drawing shapes, including an easy-to-use curve tool for drawing splines or Bezier curves.
- Unlimited History. Once you've undone an action, you can also redo it. The length of the history is only limited by available disk space.
- Open Source and Free.
Paint.Net requires the .NET Framework 2 in order to run.
Changes in recent version
New: "Tolerance Alpha Mode" toggle button added to the toolbar for the Magic Wand, Paint Bucket, and Recolor tools. This permits switching the algorithm for color comparison between premultiplied (default) and straight. "Straight" will distinguish between transparent pixels with different color values, whereas premultiplied will see them as equivalent.
New: Holding Ctrl while using the Color Picker tool will sample from the merged image (vs. just the current layer).
New: The file name in the title bar will now have a prepended asterisk when it has unsaved changes.
Changed: The image close ‘X’ button can now be clicked for images that are not currently active.
Changed: In the Text tool, Ctrl+(Backspace, Delete, Arrow Keys) has been improved to work more like Microsoft Word. Thanks to @Bruce Bowyer-Smyth for the patch!
Fixed: The Rectangle Select tool, when used to draw a constrained, fixed ratio, or fixed size selection, will now correctly clamp the rectangle to be within the canvas
Fixed: Layers -> Move Layer Up/Down/Top/Bottom was not working for images with fewer than 3 layers
Fixed: Edit -> Erase Selection will now fill with transparent black (#00000000) instead of transparent white (#00FFFFFF)
Fixed: Custom Shapes will now be displayed in a consistently sorted order
Fixed: ".pdnSave" ghost files should no longer linger when saving to the desktop. This was due to a bug in Windows and File Explorer.
Fixed crashes due to DXGI/Direct3D "lost device" or "device removed" errors that can happen for various reasons (duck/undock, driver update, low memory, etc.)
New: Plugins can now use the IArrayPoolService, a wrapper around .NET’s ArrayPool, to optimize their array allocations
