MiniMax H3 Image Features
Edit with up to 16 references
Use one image as the base for an edit, or assign different roles to several references. For example, let one guide the subject and another guide the lighting.
Ten fixed aspect ratios and Auto
Choose a fixed ratio for a specific placement, from 9:16 stories to 21:9 banners. In edit mode, Auto follows the first reference when its ratio is supported.
Pick a canvas for the job
Vertical poster with a short headline
A 4:5 canvas gives the headline and the illustration room to breathe. Put the exact words in quotes and proofread the generated lettering before export.
Ultrawide website banner
Set 21:9 for a wide header. Describe where the main subject sits and leave open space for headlines or buttons you’ll add on the site.
Change a product’s color in context
Use a reference when you already have a composition you like. In this MiniMax H3 Image edit, the prompt asked to turn the vase cobalt blue while keeping the ridges, branches, and framing.
Original
Edited
Terracotta vase recolored in cobalt
From first draft to final image
Describe the full frame
For text to image, specify the subject, angle, and light. Leave space in the composition for any copy you’ll add later.
Give each reference a role
For edits, cite uploads in order as <Picture 1>, <Picture 2>, and so on. Say which image guides the subject or layout and what to keep.
Choose how much detail you need
Start at 1K for layout checks or use the default 2K. Choose 4K when the final image needs more room for crops or fine textures.

How many references can I upload?
The editor accepts up to 16 JPEG, PNG, or WebP files, up to 20 MB each. Adding references may make a job take longer.

Can an edit keep exact lettering or layout?
Small type and precise placement can shift, particularly when combining references. Check the result at full size and add critical text in a design editor.
