Batch processing up to 30 images on Pro plan. Pro Pass at $8.83/month yearly. API available for business integration. Aggregate user rating of 4.7 but flagged as potentially inflated due to many short, generic reviews. 2026 update: Nero AI Image Upscaler in 2026 ships on web, Windows, macOS, iOS, and Android with batch processing up to 30 images per run on the Pro plan.
