Frequently Asked Questions
When should I URL encode? ▼
URL encoding is required when passing special characters (spaces, &, =, ?, #) in URLs or query string parameters. It converts unsafe characters to percent-encoded format (e.g., a space becomes %20) so they are transmitted correctly.
What is the difference between encodeURI and encodeURIComponent? ▼
encodeURI encodes a complete URL but preserves structural URL characters like :, /, ?, and &. encodeURIComponent encodes everything including those characters, making it safe for use as a value within a query parameter. Use encodeURIComponent for individual parameter values.
Can I decode a URL? ▼
Yes. Paste a percent-encoded URL or string and switch to Decode mode to see the original readable text. This is useful for debugging URLs with encoded query parameters.
