About This Tool
This social media image splitter prepares one source image for Xiaohongshu 9-grid posts, WeChat Official Account long images, X multi-image posts, and custom grids.
Use 1080×1440 portrait tiles for Xiaohongshu, a 900px or 1080px article width for WeChat, or two to four X images with a simulated platform layout and adjustable gap compensation.
Recommended safe-zone guides help keep text, faces, and logos away from likely crop areas. Processing stays in your browser with no upload, sign-up, or watermark.

Frequently Asked Questions
What does the social media image splitter create?
It creates Xiaohongshu 9-grid images, WeChat long-image exports, X multi-image layouts, and custom image grids from one source file.
What size is the Xiaohongshu 9-grid preset?
The recommended preset exports nine 1080×1440 images in a 3:4 portrait ratio. It is a workflow preset, not a permanent platform limit.
How many images can I prepare for X?
The X mode prepares two, three, or four images. The preview is simulated because final crops can vary across app versions and devices.
What is the recommended safe zone?
The dashed guide is a conservative inset for important text, faces, and logos. It is guidance rather than an official guarantee.
Are my images uploaded?
No. Image decoding, resizing, splitting, previews, and ZIP creation run locally in your browser.
Can I batch export every asset?
Yes. Download Export Pack creates a ZIP with platform-aware, numbered filenames in posting order.
