Overview
The paint.net is free image and photo editing software for Windows users. It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. It is very simple and easy to use, and specially designed to be learned through intuition without assistance or manuals. paint.net features the tabbed interface where the tabs show a live thumbnail in place of a text. These thumbnails make it easy for users to see which images they need to open when work with multiple images.

paint.net has been compared to some of the commercial digital photo editing software packages such as Adobe Photoshop, Corel Paint Shop Pro, Microsoft Photo Editor, and The GIMP.

paint.net 4.0 comes with a brand new, asynchronous, fully multithreaded rendering engine. It also improvements to various tools and a tweaked user interface.

Here is some of the most prominent changes in paint.net 4.0:

A brand new, asynchronous, fully multithreaded rendering engine

• Performance scales very well with respect to the number of CPU cores, whether you have 2, 4, 6, or even 16 of them.
• Performance scales much better with large, or even huge, images. Rendering will slow down and you will see tiles "trickling" in as they are completed, but the UI will still be responsive to your changes and clicks.
• The canvas now uses hardware acceleration via Direct2D, which also improves performance.
• Memory usage is lower.

Selections have been improved in many ways

• Antialiased selections. You may turn this on/off at any time from the toolbar.
• Selection outlines are now rendered with the "dancing ants" animation.
• Performance of selection rendering and manipulation (Move Selection tool) have been fantastically improved.

General UI

• The functionality previously provided by the Utilities, Window, and Help menus has been simplified, consolidated, and moved to the top-right corner of the main window.
• A brand new Settings dialog makes it much easier to configure all the tool and toolbar defaults, among other things.
• The zoom slider and units selector have been moved from the toolbar to the bottom right corner of the window (into the status bar).
• The image thumbnail list is now left-aligned and does not move around when you switch between certain tools.
• The image thumbnail list can now be reordered with drag-and-drop.
• Updated theming to a white, blue, flat motif.
