URL Encoder / Decoder

Encode or decode URL strings safely.

What is URL Encoder / Decoder?

URL Encoder and Decoder converts text into a format that is safe for URLs (percent-encoding).

How Does It Work?

The tool uses JavaScript's native encodeURIComponent() and decodeURIComponent() functions, following RFC 3986.

Common Use Cases

  • Query string parameters - Encode values containing spaces or symbols.
  • URL debugging - Decode a URL that has already been encoded.
  • Form submission - Make sure form data is encoded correctly.
  • API testing - Encode paths containing special characters.
  • Cleaning up URLs - Remove double-encoding.

Frequently Asked Questions

Q: What's the difference between encodeURI and encodeURIComponent?

A: encodeURIComponent is more aggressive, encoding &, =, ?, and + as well, which is needed for query strings.

Q: Why does a + turn into a space when decoding?

A: The tool uses the standard decodeURIComponent, so + remains a +.

Q: Does it follow RFC 3986?

A: Yes, it follows the standard URI generic syntax.
