H3 Image is a browser-based image generator and editor built on MiniMax H3 Image. Instead of describing every material, garment and light source from scratch, you upload reference images, give each one a role - person, outfit, product or setting - and add a short instruction that explains how they should combine.
The idea is simple: your photos are the brief. A typical edit might take a person from one image, a coat from a second image and a room from a third, then ask for a natural waist-up portrait that keeps the face, hairstyle and collar while matching the room's warm light. Another workflow puts an unbranded product bottle on a new pedestal set with matching window light.
The workspace supports up to 16 reference images, 2K and 4K presets, and further edits that start from a saved output. It runs entirely in the browser, so there is no model download, GPU configuration or ComfyUI installation. One published square portrait was generated directly at 4096 x 4096 without a separate upscaling step.
Because these are generative edits, fine text, small product geometry, identity details and scene proportions should be reviewed before commercial use. The examples on the site show the original inputs, the exact instruction and the saved output, so you can judge the process rather than only a polished result.
Use cases include portrait concepts, product-scene visuals, interior and furniture explorations, and lighting experiments on an existing photo. A single-image edit can request a new lighting treatment while preserving the person, pose and setting; multi-reference edits combine separate inputs with clearly assigned roles.
Pricing
New accounts receive 15 free credits once, with no card required. A one-reference 2K edit uses 13 credits; each additional reference adds 3, so a three-reference 2K edit uses 19. Paid credits come in one-time packs starting at $9.90 for 300 credits, with larger packs available, and purchased credits do not expire. There is no subscription.
