Paint.NET still edits photos for free, but its hardware requirements have moved on

Paint.NET has outlived quite a few promises that a browser would replace every desktop application. The download still does the work locally, and the original free route is still there.

The project’s site traces the editor to a college project mentored by Microsoft, intended as a replacement for Windows Paint. It now offers layered editing, effects, undo and an extension community. The direct download is free, while a paid Microsoft Store version provides another way to obtain it and support its development.

The name can make this comparison confusing. Paint.NET is a separate application from Windows Paint. Microsoft’s current Paint page describes layers in its own bundled editor, so an old recommendation based only on getting layers needs a new explanation. Two paint cans can share a label without holding the same finish.

The practical difference shows up in the editing job. Paint.NET’s documentation covers blend modes, adjustments, effects and multiple open images. Someone combining a screenshot with annotations and a cutout needs to know how those pieces remain editable. A feature checklist that stops at layers leaves the interesting part under the lid.

Its documentation calls PDN the “native file format” and explains that it preserves the layered project. Exporting an ordinary flattened image creates something other applications can display without preserving that stack. Keeping the PDN alongside the exported PNG or JPEG lets a future correction move the caption without repainting everything beneath it. Save the sandwich before someone melts all the cheese together.

The current download page lists version 5.1.12, released March 8, 2026. Its requirements include Windows 11 or Windows 10 version 21H2 or newer, supported 64-bit processors, and a Direct3D 11 graphics device. On x64 systems, the requirement is “AVX2.” The installer includes its required .NET runtime; users needn’t turn dependency hunting into an additional hobby.

Undo has a physical limit too. Paint.NET describes an extensive undo history, but the documentation ties storage to available memory and disk space. Large images with many layers can make the temporary-storage requirement relevant. Unlimited is a cheerful word until the drive asks to see the receipt (capacity still applies).

A useful choice between Paint and Paint.NET starts with an actual recurring edit: which selections, adjustments and layer operations it needs, and whether a reusable project saves time afterward. The bundled app may cover a simple job. A more elaborate composition deserves its own trial on a copy of the image, rather than an argument over which program has the older recommendation.

The next revision still needs layers.
