Expert Tip
Our AI performs best on 1k to 4k content that has at least 200x200 pixel resolution. Extremely tiny sources (under 100px) may produce artifacts. For these cases, try 2x upscale first.

ImageUpscaler produces consistent, artifact-free results for 1k to 4k. Our AI has been fine-tuned to avoid common issues like haloing, over-sharpening, and unnatural textures that plague competing tools.
