Upscaling Your Images

Enhance resolution and quality with AI-powered upscalers


AI upscaling takes your images to the next level by increasing resolution while adding realistic detail. This guide covers everything you need to know about LetzAI's upscaling capabilities.


What is AI Upscaling?

Unlike traditional upscaling that simply stretches pixels, AI upscaling intelligently generates new details. The result is sharper, more detailed images at higher resolutions - perfect for printing, professional use, or simply getting more out of your AI creations.



Our Upscaling Models

Magnific

Our premium upscaler powered by Freepik's technology. Magnific offers:

  • Up to 16x resolution increase
  • Exceptional detail generation
  • Customizable creativity levels
  • Best for portraits, products, and detailed scenes

Standard Upscalers

Fast, efficient upscaling for everyday use:

  • Allows you to choose a range between 4 & 12 Megapixels
  • Basic control over upscaling intensity with our strength slider
  • Lower credit cost
  • Quick processing times
  • Good for general enhancement


How to Upscale

  1. Navigate to Upscale: Click the Upscale tab
  2. Upload or select image: Choose the image you want to enhance
  3. Choose your upscaler: Select based on your needs and budget
  4. Set scale factor: Choose how much to increase the resolution
  5. Adjust settings: Configure creativity/enhancement levels if available
  6. Generate: Process the image and download your result


Creativity Settings (Magnific)

Magnific allows you to control how much the AI "reimagines" your image:

  • Low creativity: Stays faithful to the original, minimal hallucination
  • Medium creativity: Balanced enhancement with some added detail
  • High creativity: More aggressive detail generation, may alter the image more

For portraits and precise work, use lower creativity. For artistic pieces or landscapes, higher creativity can add beautiful detail.



Understanding Scale Factors

  • 2x: Doubles both dimensions (4x total pixels). Good for moderate enhancement.
  • 4x: Quadruples both dimensions (16x total pixels). Great for print-ready images.
  • 8x and higher: For extremely high-resolution needs like large prints or professional work.

Example

Starting with a 512x512 image:

  • 2x = 1024x1024 pixels
  • 4x = 2048x2048 pixels
  • 8x = 4096x4096 pixels


Best Practices

Start with Quality

  • Upscaling works best on images that are already reasonably clean
  • Heavily compressed or very low-resolution images may not upscale well
  • If possible, generate images at higher quality settings before upscaling

Choose the Right Scale

  • Don't over-upscale - going too large can introduce artifacts
  • Consider your final use case (screen viewing vs. print)
  • For most online uses, 2x-4x is sufficient


Use Cases

Print Production

AI-generated images are often created at lower resolutions. Upscale to 300 DPI or higher for professional printing.

Social Media

While platforms compress images, starting with higher resolution gives better quality after compression.

Website and Portfolio

Create crisp, professional-looking images for showcasing your work.

Restoring Old Photos

Upscaling can breathe new life into old, low-resolution photographs.



Comparing Before and After

LetzAI includes a before/after comparison slider so you can see exactly what the upscaling has done to your image. Use this to:

  • Verify the enhancement meets your expectations
  • Check for any unwanted changes or artifacts
  • Compare different settings or upscalers


Credit Costs

Upscaling costs vary based on:

  • Model used: Premium upscalers like Magnific cost more
  • Scale factor: Higher scale factors use more credits
  • Image size: Larger input images may cost more to process

Check the credit cost display before generating to avoid surprises.



Troubleshooting

Upscaled image looks artificial

  • Try a lower creativity setting
  • Use a different upscaler
  • Scale by a smaller factor

Details are blurry

  • Increase creativity slightly
  • The original may be too low quality
  • Try Magnific for better detail generation

Faces look wrong

  • Use lower creativity for portraits
  • Consider face restoration tools before upscaling


Workflow Recommendations

For best results, follow this workflow:

  1. Generate your image at the highest practical quality
  2. Edit to fix any issues while at lower resolution (faster/cheaper)
  3. Upscale only when you're happy with the image
  4. Final adjustments can be made in external software if needed
