Character Count with Platform Limits

Each platform has different character limits. Twitter/X allows 280 characters, Instagram captions can be up to 2,200 characters, LinkedIn allows 3,000, and Facebook permits up to 63,206 characters. The tool shows a real-time character count and a color-coded progress bar that warns you as you approach the limit.
