Frequently Asked Questions
How are the internal anchor links generated?
Based on standard Markdown specs, we automatically generate anchor links by converting header text to lowercase and replacing spaces with hyphens (e.g., `[Header](#header)`). This works natively on GitHub and most platforms.
What happens if headers contain code blocks or special characters?
The tool tries to extract them as plain text as much as possible, though some complex markdown inside headers may not match the anchor ID exactly depending on the platform.
Is this tool free to use?
Yes. No registration or payment is needed. Generate as many Markdown TOCs as you need.
Is it safe to input highly sensitive text?
Yes. Header extraction and link generation run completely within your local browser. Document outlines and heading hierarchies are never stored or transmitted.
