Examples

1. Multi-Channel Product Launch Campaign

Social Media Manager
Background
A marketing team is launching a new product and needs to post the announcement graphic across Instagram, LinkedIn, and X simultaneously.
Problem
Manually cropping the master graphic into different aspect ratios for each platform is tedious and slows down the launch schedule.
How to Use
Upload the master PNG graphic, set the crop strategy to 'Attention' to keep the product centered, choose 'JPEG' output at 90% quality, and check 'Include Manifest'.
Example Config
{
  "cropStrategy": "attention",
  "outputFormat": "jpeg",
  "quality": 90,
  "includeManifest": true
}
Outcome
A ZIP file containing nine perfectly cropped images tailored for each social network, along with a manifest file mapping each image to its platform.

2. Optimizing Photography for Visual Platforms

Content Creator
Background
A creator wants to share a high-resolution landscape photo on Instagram and Xiaohongshu without losing the main subject.
Problem
Standard center-cropping might cut out key elements of the composition, requiring manual adjustments.
How to Use
Upload the high-resolution WebP photo, select the 'Entropy' crop strategy to focus on high-detail areas, set the output format to 'WebP' at 85% quality, and generate the pack.
Example Config
{
  "cropStrategy": "entropy",
  "outputFormat": "webp",
  "quality": 85,
  "includeManifest": false
}
Outcome
A ZIP archive containing WebP crops optimized for visual platforms, preserving the most detailed parts of the original photo.
