Pixel Snapper
Free tool from Sprite Fusion that snaps messy, blurry or inconsistent pixel art onto a clean pixel grid.
What is Pixel Snapper?
Pixel Snapper is a free tool by Sprite Fusion that automatically fixes messy, blurry or inconsistent pixels and aligns them to a tidy pixel grid. It is aimed at cleaning up imperfect pixel art, including images produced by AI generators such as Nano Banana and GPT Image 2, while keeping fine details like dithering and curves. The web edition runs in the browser with no account required, and a paid desktop edition adds offline use and batch processing. The project is open source with its code on GitHub.
Key Features
Automatic grid snapping
Detects misaligned pixels and corrects them onto a consistent pixel grid.
Detail preservation
Keeps fine elements such as dithering and curves intact while cleaning up the image.
AI art clean-up
Designed to tidy pixel art from generators including Nano Banana and GPT Image 2.
Browser-based web edition
Runs directly in the browser with no account or installation required.
Upload support
Accepts PNG and JPG files up to 10MB with up to 16 colours.
Open source
Source code is published on GitHub for both the web and desktop editions.
Desktop batch processing
The desktop edition adds offline use and fast batch processing across many files.
Pros & Cons
Advantages
- The web edition is free for both hobby and commercial projects with no sign-up needed.
- It targets a specific, common problem of cleaning up AI-generated and inconsistent pixel art.
- The code is open source, so users can inspect and self-host it.
- The one-off desktop edition is inexpensive and includes lifetime updates with no subscription.
- It fits into game development workflows alongside engines like Unity, Godot and Phaser.
Limitations
- The makers state it is not a magic fix and some images will still need manual touch-ups in tools such as Aseprite.
- Uploads are capped at 10MB and 16 colours, which limits more detailed or higher-colour images.
- Offline use and batch processing require paying for the desktop edition.
- There is no live chat or formal support channel beyond a Discord community.
