How to Use Hires.Fix in Krita AI Tools for High-Resolution Image Enhancement
Krita, a popular open-source digital painting software, now features AI-powered tools that allow artists and creators to enhance their images with incredible detail. One such feature is hires.fix, designed to upscale images and improve their quality while preserving fine details. This makes it ideal for AI-generated artwork, illustrations, or any digital image that needs high-resolution refinement.
What is Hires.Fix?

Hires.Fix is a tool within Krita’s AI toolkit that increases the resolution of an image. Unlike simple upscaling, it uses AI algorithms to maintain sharpness, textures, and important features in your artwork. This ensures that the final image looks natural and professional, even at larger sizes.

Hires Fix, Super Resolution, or Upscale Image.

Tips for Best Results

- Start with the largest base image possible for better upscaling.
- Avoid over-denoising, as it may remove important details.
- For extreme upscaling, consider iterative upscaling (e.g., 2x twice instead of 4x once).
- Combine Hires.Fix with Krita’s native filters like Sharpen or Detail Enhancement for extra refinement.
