AI-Optimized Social Media Bios Tailored to Every Platform
Social Bio Formatter is a free AI tool that generates platform-optimized bios for Instagram (150 chars), Twitter/X (160 chars), Facebook (101 chars), LinkedIn (220 chars), TikTok (80 chars), YouTube (1,000 chars), Pinterest (160 chars), Threads (150 chars), and GitHub (160 chars). Enter your bio once and get tailored versions that respect each platform's character limits and best practices.
Platform-Specific Character Limits and Best Practices
Every social media platform has different character limits and audience expectations. A LinkedIn bio that works for professional networking won't fit on TikTok's 80-character limit. This tool automatically adapts your message to each platform's constraints.
Generate bios for all 9 platforms at once or pick a specific platform from the dropdown. Each generated bio includes a live character count so you know exactly how much space you have left.
