PaintDim vs Paint.NET — Which Free Image Editor Is Better?

April 2025 · 6 min read

Paint.NET has been a go-to free image editor for Windows users since 2004. It started as a Microsoft Paint replacement and grew into a capable tool with layers, effects, and a plugin ecosystem. But it has some fundamental limitations that haven't changed in 20 years.

PaintDim is a newer, browser-based editor that offers more built-in features and runs on any operating system. Let's compare them head to head.

The big difference: browser vs desktop

Paint.NET is a Windows-only desktop application. You need to download and install it, and it only runs on Windows. If you're on macOS, Linux, or a Chromebook — you're out of luck.

PaintDim runs entirely in your browser. Open the website, and you're editing. Works on Windows, macOS, Linux, ChromeOS — any device with a modern browser. No installation, no updates to manage.

Where PaintDim wins

Layer groups

PaintDim supports layer folders — you can organize dozens of layers into collapsible groups, just like Photoshop. Paint.NET has a flat layer list with no grouping, which gets messy fast on complex projects.

Layer effects

PaintDim has built-in layer effects: stroke (outline), outer glow, and inner glow. These are non-destructive and adjustable. Paint.NET has no layer effects — you'd need third-party plugins to achieve similar results.

Editable text

In PaintDim, text lives on its own layer and stays editable. You can change the font, size, or content anytime. In Paint.NET, text is immediately rasterized — once you click away, it becomes pixels. Want to fix a typo? Undo and retype everything.

Vector shapes

PaintDim has dedicated vector layers where shapes remain editable — you can move, resize, and change the fill or stroke of a rectangle after creating it. Paint.NET rasterizes shapes immediately, just like text.

Selection tools

PaintDim offers polygon lasso (click-to-add-points freeform selection) in addition to the standard tools. It also has selection operations: smooth, expand, and contract — useful for refining selections. Paint.NET has basic selection tools but lacks these refinement options.

Cross-platform

PaintDim works on any OS. Paint.NET is Windows-only. If you use a Mac or Linux, PaintDim is one of your best free options.

Where Paint.NET wins

Plugin ecosystem

Paint.NET has a large community of plugins that add features like advanced color grading, noise reduction, 3D effects, and file format support. PaintDim currently has no plugin system.

More export formats

Paint.NET natively supports BMP, TGA, TIFF, and its own .PDN format (which preserves layers). PaintDim exports to PNG, JPEG, and WebP.

Desktop performance

For very large images (8000x8000 pixels and above), a native desktop app will generally handle memory and processing better than a browser-based tool. For typical image sizes, both perform well.

The bottom line

Paint.NET is a solid editor that served Windows users well for two decades. But it hasn't kept up with modern needs — no layer groups, no editable text, no vector layers, and Windows-only.

PaintDim delivers more built-in features, works on any platform, and requires zero setup. For most image editing tasks in 2025, it's simply the more practical choice.
