Create Post
How to craft multi-channel posts with network-specific captions, image/video aspect ratio validation, and custom tags.
Overview
Publishing across multiple social networks traditionally requires logging into separate tools and manually reformatting text and images. Hyperfast Publish lets you create once with real-time media validation and channel-specific customization.
Step-by-Step Instructions
Open Create Post
Click 'Create Post' in the top header or navigate to Publish > Create Post in the sidebar.
Select Target Channels
Check the badges for each social account you wish to publish to (e.g. Instagram + Facebook + LinkedIn).
Write Master Caption & Add Media
Enter your core message. Upload images, select from your File Manager, or pick AI-generated graphics from your Brand Assets.
Fine-tune Channel Specific Overrides
Click the tab for each selected platform to tweak text length, add network-specific hashtags, or adjust mentions.
Publish Immediately or Add to Queue
Select 'Publish Now' for immediate distribution or 'Add to Queue' to let HyperFast schedule the post for optimal engagement hours.

Troubleshooting & Edge Cases
Instagram post fails validation?
Ensure your image matches standard aspect ratios (1:1 square, 4:5 portrait, or 1.91:1 landscape). Ultra-wide or non-standard ratios will be flagged before submission.
