The Image Upscaler enlarges your images to 2K, 4K, or 8K resolution using AI — without the blurry, pixelated results you get from traditional resizing. The model reconstructs fine detail so your image looks sharper at a larger size, not just stretched. Cost: 100 credits per image.Documentation Index

Common use cases
Product photos
Enlarge product images taken on a phone or in lower-resolution conditions to meet e-commerce platform requirements (typically 2000×2000 px or larger) without reshooting.
Portraits and headshots
Recover detail in older or compressed portrait photos. The AI preserves skin texture and facial features rather than smoothing them out.
Artwork and illustrations
Upscale AI-generated images or scanned artwork to print-ready dimensions. Works well on both photorealistic images and illustrated styles.
Marketing and advertising
Bring archival or low-resolution brand assets up to the resolution required for large-format ads, banners, and signage.
