Text Utilities and Character Counter
This text utilities tool collects small but frequent text tasks in one place: counting characters and lines, cleaning whitespace, escaping HTML, and preparing text for documentation, forms, code snippets, or content workflows.
When it helps
- Check character limits: Review lengths for meta descriptions, social posts, ads, and form fields.
- Prepare safe snippets: Escape HTML before displaying code or text in documentation.
- Clean up text: Remove extra spaces, normalize line breaks, and inspect line counts.
Keep the original text
Some transformations are difficult to reverse once they have been applied multiple times. When editing important text or code snippets, keep the original nearby before running cleanup, escaping, or replacement operations.
