图片超清 - AI超分辨率

When is AI super-resolution useful?

Super-resolution is helpful when you only have low-resolution photos, small images downloaded from social media, or avatars and product shots that need to be enlarged for printing, banners or high‑resolution displays. AI upscaling can increase resolution 2x, 4x or more while trying to preserve details.

Typical use cases include restoring old photos, upscaling ecommerce product images, enlarging profile pictures after cropping, and preparing assets for design layouts that require higher pixel density.

Recommended upscaling factors and quality tips

As a starting point, a 2x upscale works well for most photos, providing a noticeable quality boost without making the image look overly artificial. For cleaner originals you can try 4x upscaling, while heavily noisy or blurry photos should be treated more conservatively.

After upscaling, a touch of sharpening and denoising can help refine the result. Avoid repeatedly upscaling the same image multiple times, as artifacts will accumulate. If the final destination is the web, you can still reduce resolution slightly and compress the file to keep loading times reasonable.
