Frequently Asked Questions
What is URL encoding?▾
URL encoding replaces unsafe characters in a URL with percent-encoded equivalents (e.g., space becomes %20). This ensures URLs are valid and transmitted correctly.
What is the difference between component and full URL encoding?▾
Component encoding (encodeURIComponent) encodes everything except letters, digits, and a few characters. Full URL encoding (encodeURI) preserves URL structure characters like :, /, ?, and #.
Is my data secure?▾
Yes, all encoding and decoding happens in your browser. No data is sent to any server.
