AI images often lack the resolution needed for clear, large-format printing. Fortunately, LetsEnhance.io makes it simple to upscale these images to high resolutions suitable for posters, banners, and large prints without losing detail or clarity.

Takeaways

  • You can easily upscale AI art up to 16x their original size (up to 512MP resolution) using LetsEnhance.
  • Select the best upscale type (Balanced, Gentle, Strong, Ultra, Digital Art) according to your image's purpose.
  • Get print-ready sizes with built-in Printing Presets (posters, photo, international).
  • AI upscaling is quicker and provides better quality results compared to older methods.

Why upscale AI images?

Most AI images typically max out at resolutions around 1024x1024 pixels. This resolution is acceptable for screens but insufficient for print. Large prints need enough pixels at the intended DPI (dots per inch). For hand-held prints, aim for 300 DPI; for wall posters viewed from a distance, 150–225 DPI can look great.

Print size (in) 300 DPI (px) 200 DPI (px) 150 DPI (px)
12 × 18 3600 × 5400 2400 × 3600 1800 × 2700
18 × 24 5400 × 7200 3600 × 4800 2700 × 3600
24 × 36 7200 × 10800 4800 × 7200 3600 × 5400
36 × 48 10800 × 14400 7200 × 9600 5400 × 7200

Step-by-step guide to upscale AI art using LetsEnhance.io

Step 1: Upload your image
Visit LetsEnhance.io and drop your AI-generated image, browse or import from Files or Google Drive.

Step 2: Select the upscale method best suited for your image

  • Digital Art: Ideal for illustrations, cartoons, anime, and artistic pieces. Suitable for smaller prints, like A4 size.
  • Balanced (Default): Medium-strength enhancement that works well for general images and moderate-sized posters. Enhances clarity without dramatic changes.
  • Gentle (formerly Smart Resize): Subtle upscale ideal for images with small text, detailed product photography, or graphics. Maintains original detail fidelity.
  • Strong: Delivers maximum sharpness for blurry or low-quality sources. Great for cases where you want a noticeable, dramatic improvement.
  • Ultra: Designed for both preserving high-quality details and restoring heavily degraded images. It intelligently adapts to the source, rebuilding clarity in low-quality inputs.
💡
Pro tip: For precise dimensions and text-heavy graphics, start with Gentle. If edges feel soft, try Balanced or Ultra.

Step 3: Use Printing Presets (optional)
Select predefined printing options from the Printing Presets panel. Choose between standard sizes like Poster, Photo, or International Paper. For example, selecting a 24x24 inch poster preset automatically upscales your image to 7200x7200 pixels, ensuring optimal print quality.

Upscaling AI image with LetsEnhance

Side-by-side comparison of original vs upscaled AI image
Before/after showing improved clarity after Ultra model enhancement.

The difference between an original AI image and an upscaled version is noticeable, with significant improvements in sharpness, clarity, and overall print readiness. In this case, we used the Ultra model, selected a 4× scale and applied the Printing Preset for a 24×36 inch (61×91.4 cm) poster. Also, we set the two enhancement parameters, Size of Changes and Intensity, to 10%.

The Size of Changes setting determines how much of the image is refined. At 0%, the upscaler stays close to the original, focusing on fine texture improvements, while 100% allows for more creative reconstruction across larger areas. The Intensity setting controls how strongly the enhancement is applied. At 0%, you get a subtle, high-fidelity polish that maintains full realism; at 100%, the algorithm performs a more powerful transformation to rebuild and enhance detail.

You can easily set the exact inches, DPI, or pixel size required for your project, ensuring that every print meets professional standards.

FAQs

What DPI is best for large-format printing?

Typically, 300 DPI is recommended for high-quality prints. For very large prints (banners or billboards viewed from a distance), 150-225 DPI may suffice.

How do I size my image for print?

Multiply inches × DPI (width and height). Or choose a ready-to-use Printing Preset in LetsEnhance.io to get the right pixel dimensions instantly.

How do you upscale low-quality AI images for large prints?

Upload your image to LetsEnhance.io, and select either Digital Art, Balanced or Ultra upscale modes. Use Printing Presets for predefined sizes or customize your dimensions.

Can Photoshop or Lightroom upscale AI images?

Photoshop and Lightroom can upscale images using tools like Adobe Enhance or Lightroom Super Resolution. However, these methods often produce mixed results, are slower, and require more manual tweaking compared to specialized AI upscalers.

What is the best upscaler for preparing AI images for print?

LetsEnhance.io is the best choice due to its superior output quality, fast cloud processing, ease of use, variety of upscale modes, and exceptional resolution limit of up to 512MP. Alternatives include:

  • Gigapixel AI: Good quality but slower processing and resource-intensive.
