Image Upscaler: How to Enhance Low-Resolution Photos with AI

Low-resolution images are everywhere — old photos, web images, compressed downloads. AI upscaling can enhance them to higher resolutions without the blur or pixelation of traditional upscaling. Here's how on Crevisto.

What the Image Upscaler does

The Image Upscaler uses AI to increase the resolution of an image while preserving (or even enhancing) detail. The result includes:

• Higher resolution — 2x, 4x, or more
• Preserved detail — no blur or softening
• Reduced artifacts — compression artifacts are cleaned up
• Enhanced sharpness — edges are crisp and clear
• Natural look — the result looks like a native high-res photo

How to upscale an image

1. Visit the Image Upscaler

2. Upload your low-resolution image

3. Select the upscale factor (2x, 4x)

4. Click "Generate"

5. Download your high-resolution image

Tips for best results

• Start with the best source you have — less compression means better results
• Don't over-upscale — 2x is usually enough; 4x works on good sources
• Crop first — upscaling a crop is better than upscaling then cropping
• Use lossless input — PNG or TIFF, not JPG

Using the CLI

curl -fsSL https://crevisto.com/install.sh | sh
crevisto trial
crevisto generate image-upscaler --input photo=./low-res.jpg --scale 4 --output ./upscaled.webp

Batch processing

for photo in ./low-res/*.jpg; do
  crevisto generate image-upscaler --input photo="$photo" --scale 2 --output "./upscaled/$(basename "$photo" .jpg).webp"
done

Use cases

• Old photos — enhance scanned family photos
• Web images — upscale for print or higher-res displays
• Product photos — enhance low-res product images
• Social media — post high-quality images
• Print — prepare web images for print
