Image Upscaling

Increase image resolution using AI upscaling models. Enhance low-resolution images, upscale generated images, or prepare images for print.

How It Works

  1. Have an image - Generated image or uploaded image

  2. Click "Transform" button - On the image thumbnail

  3. Select upscaling model - Choose Topaz, Recraft, or Sima

  4. Set scale factor - 1.5×, 2×, 3×, or 4× (varies by model)

  5. Configure settings - Model-specific options

  6. Upscale - Click to start upscaling

  7. Get result - Higher resolution image

Natural Language Upscaling

You can also upscale using natural language:

  • "Upscale this image" - Automatically uses Recraft Crisp Upscale

  • "Enhance the quality" - Upscales the image

  • "Make this higher resolution" - Increases resolution

The AI automatically detects your intent and routes to upscaling.

Use Cases

Enhancing Generated Images

Example:

  • Generate image at 1024×1024

  • Click "Transform" → Select Topaz

  • Set scale to 2×

  • Upscale to 2048×2048

  • Result: Higher resolution for print/web

Restoring Low-Resolution Images

Example:

  • Upload low-res image (e.g., 640×480)

  • Use Topaz "Low Resolution V2" model

  • Set scale to 4×

  • Upscale to 2560×1920

  • Result: Restored, enhanced image

Preparing for Print

Example:

  • Have image at screen resolution

  • Use Topaz "High Fidelity V2"

  • Set scale to 3× or 4×

  • Upscale to print resolution

  • Result: Print-ready high-res image

Face Enhancement

Example:

  • Upload portrait photo

  • Use Topaz with face enhancement enabled

  • Set scale to 2×

  • Upscale

  • Result: Enhanced face details

Scale Factor Guidelines

1.5× Upscaling

Use when:

  • Slight resolution increase needed

  • Quick enhancement

  • Maintaining file size

  • Minor quality boost

2× Upscaling

Use when:

  • Standard upscaling

  • Doubling resolution

  • Most common use case

  • Good balance

3× Upscaling

Use when:

  • Significant resolution increase

  • Preparing for large displays

  • High-quality output needed

  • More processing time

4× Upscaling

Use when:

  • Maximum upscaling

  • Very low-res source images

  • Print preparation

  • Maximum quality needed

Tips for Best Results

  1. Start with quality source - Better input = better output

  2. Choose appropriate model - Topaz for quality, Recraft for speed

  3. Match scale to needs - Don't over-upscale unnecessarily

  4. Use face enhancement - For portraits, enable face enhancement

  5. Consider output format - PNG for quality, JPEG for size

  6. Test different models - Some work better for specific image types

  7. Iterate if needed - Can upscale multiple times if needed

Troubleshooting

"Upscaling is too slow"

Solutions:

  • Use Recraft Crisp for faster results

  • Lower scale factor (2× instead of 4×)

  • Smaller images upscale faster

  • Check internet connection

"Quality not improved enough"

Solutions:

  • Use Topaz "High Fidelity V2" model

  • Try higher scale factor

  • Ensure source image is good quality

  • Try different model (Sima for detail)

"Faces look distorted"

Solutions:

  • Enable face enhancement (Topaz)

  • Use lower scale factor

  • Try "High Fidelity V2" model

  • Check source image quality

"Upscaling not available"

Solutions:

  • Ensure you have an image attached

  • Click "Transform" button on image

  • Check that upscaling models are available

  • Verify API keys are configured
