Detailed result requirements

Required inputs

Required original image to be expanded (1 picture) + required target ratio or new canvas range (1 set)

Input quality

JPEG, PNG, HEIC/HEIF, WEBP or SVG.

Composition

No universal public standard is available. Check the requirements of the platform or service you will use.

Output aspect ratio

Set the output canvas from the selected platform placement or production template, not from a reference image. Choose the target aspect ratio before generation; do not default to 1:1. Use a custom ratio only when the actual placement or production template requires it. The aspect ratio for complete image at the new aspect ratio must follow the selected platform, device, finished format, or production template. If no target ratio is provided, request it before generation; never infer it from a reference image. Create one aspect-ratio-specific deliverable per request; generate each additional placement as a separate output. Recompose for the selected ratio while preserving the complete subject, all text, and every required safe area. Never stretch the subject or treat cropping important content as adaptation.
