What Is Threads Post Formatter?

The Threads Post Formatter prepares your text for Meta's Threads platform with character limit awareness and automatic thread splitting. Threads has a 500-character limit per post and does not support Markdown formatting, so this tool strips any markdown syntax, converts links to plain text, and ensures your post fits within the limit. If your text exceeds 500 characters, the formatter automatically splits it into multiple posts at natural sentence boundaries, creating a ready-to-post thread. Each segment is numbered and shows its individual character count, making it easy to copy and post sequentially.

Technical Guide

Meta originally launched Threads with a lower character limit, later expanding it to the current 500 characters per post. The platform supports plain text, links, mentions (@), and emojis but does not support Markdown, HTML, or rich text formatting. Threads posts appear in followers' feeds and can be discovered through search. The platform is text-first with optional image/video attachments. When creating threads (multi-post sequences), each post is independent with its own 500-character limit. Our formatter handles the splitting by finding natural break points at sentence endings, ensuring no post is truncated mid-thought.

5
Cross-post threads to maximize reach across platforms
