This update has a handful of small improvements and bugfixes, and many improvements and fixes for GPU effect plugin development.

Get the Update

There are two releases of Paint.NET:

• Microsoft Store release (recommended)
  • You can purchase it here. This helps fund development and is an alternative or supplement to sending in a donation.
  • If you already have it installed, the update should happen automatically once Microsoft certifies the update, usually within the next day or so. To get the update immediately (once it’s certified), you can follow the instructions listed here.
• Classic Desktop release
  • Download the installer from the website. This is the recommended download if you don’t have Paint.NET installed. It can also be used to update the app.
  • If you already have it installed, you should be offered the update automatically within the next few days, but you can also get it immediately by going to ⚙ Settings -> Updates -> Check Now.
  • Offline Installers and Portable ZIPs are available over on GitHub.

Change Log

Changes since v5.0.9:

• New: Edit -> Paste now supports base64-encoded images, which enables copying images from Microsoft Teams (thanks @null54 for the implementation!)
• Fixed a rare bug that would cause selection tools to not work until the image was closed and reopened
• Fixed: All mouse cursors will now honor the Windows setting for adjusting the mouse pointer size
• Fixed a rare crash when rapidly undoing multiple actions
• New: Plugins can now access the built-in JPEG and PNG FileTypes through two new methods on IFileTypesService
• New: The Paint.NET Plugin API Documentation website is now live at https://paintdotnet.github.io/apidocs/
• Fixed: All of the custom Direct2D effects now have runtime metadata (DisplayName, Author, Category, Description), which is useful for a UI that lets the user browse them (e.g. node editor)
• New: Added convenience constructors to many Direct2D effects so that they can be used without declaring a new local variable
• New: Added GaussianBlurMapEffect and BokehBlurMapEffect for use by GpuEffect plugins. They enable the blur radius to be controlled per-pixel through the use of a second input image (the “map”)
• New: Added a RandomNoiseEffect that GpuEffect plugins can make use of
• Fixed various bugs with HlslBinaryFunctionEffect, HlslBinaryOperatorEffect, and HlslTernaryFunctionEffect (which can be used by GpuEffect plugins)
• Added Distance and Dot to the list of HlslBinaryFunctions
• Added Length and Mad (multiply-add) to the list of HlslTernaryFunctions
• Fixed the Environment property’s runtime type when accessed from an EffectConfigForm (for BitmapEffects and GpuEffects with custom UIs)
• Fixed UIScaleFactor’s methods for converting between DIPs and pixels
• Fixed ability to work with EffectConfigForms in the Visual Studio WinForms designer
• Updated the bundled AvifFileType to version 1.1.26 (thanks @null54!)
• Updated the bundled DdsFileTypePlus to version 1.12.6 (thanks @null54!)
• Updated the bundled WebPFileType to version 1.3.20. It now uses libwebp v1.3.2 which contains the fix for CVE-2023-4863/CVE-2023-5129 (thanks @null54!)
