Complete Guide to PixAI’s 6 AI Image Enhancement Tools
Below is a detailed breakdown of each AI enhancement preset, what it does, and pro tips for getting the best results.
Hand Fix — AI Hand Fixer for AI-Generated Images
What It Does
The Hand Fix tool automatically improves the quality of hands in your AI artwork — the go-to AI hand fixer for fixing blurry digits, refining nail shapes, and sharpening hand textures.
Please note that the Hand Fix tool is specifically designed to enhance existing details and improve the clarity of hand textures. It cannot correct anatomical errors such as removing extra fingers or fixing merged limbs. For significant structural issues, we recommend using the Edit feature, Flow Edit, or PixAI Reference Pro for a complete manual correction.

- Select the Hand Fix tool from the enhancement menu
- Click Generate and let the AI hand fixer work its magic — no additional input required!
