This update improves reliability of saving, further improves Copy/Paste functionality, and fixes some other miscellaneous bugs. I decided to port the “fault-tolerant save” work I did in the v4.0 codebase back to v3.5.x so that this much-needed reliability improvement could be made available now.

As usual, you can get it either by downloading it from the website, or via the built-in updater (Utilities -> Check for Updates). If you use the built-in updater, please make sure that "Also check for pre-release (beta) versions" is enabled.

You can also visit the forum to discuss this: 

  • Saving an image is now fault-tolerant. If there is an error or crash while saving, the original file will be left alone.
  • Worked around a bug in some plugins that are incorrectly using the built-in Gaussian Blur effect. For example, Sharpen+. Now they won’t crash.
  • Fixed a bug with Edit->Paste into New Image, where the new image would be 1 pixel too wide or tall, as reported at
  • Fixed a bug with the Rectangle Select tool and Fixed Ratio selection, which would be off by 1 pixel, as reported at
  • When pasting an image from Paint.NET into Paint.NET, it will be a little smarter about where it puts the image. Previously, if the location wasn’t within the viewport, it would be placed at the top-left corner of the viewport. Now it will find the nearest point along the edge of the viewport to place the image.
  • The EXIF rotation ("orientation") metadata is now discarded when opening an image, which was causing aggravation with images that could then never be reoriented correctly using Image->Rotate
  • The EXIF tags for JPEG thumbnail data are now correctly discarded.
  • Fixed a potential memory leak in the Gaussian Blur effect.
  • Fixed a typo in the Italian translation. In the setup wizard it was referring to "Pain.NET" (woops)
