Everything You Need to Know About AI Image Upscaling

Unlike bicubic resizing that stretches blurry pixels, our AI image upscaler reconstructs missing edges, micro-texture, and clarity.

01 / FIDELITY

Preserve Details Without Distortion

Traditional enlargers blur edges or add halos. Our AI image upscaler rebuilds authentic skin texture, foliage, and typography. In the AI image upscaler, 2× is ideal for very low-resolution originals, while 4× shines on photos with existing detail.

  • 4×–16× AI image upscaler up to 4096 px
  • Zero halos in the AI image upscaler
02 / DE-ARTIFACT
