Tip
Use encodeURIComponent() for query values and encodeURI() for the full URL path.
Did You Know?
A space can be encoded as either %20 or a plus sign (+) depending on the web standard being used.
URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be replaced with a '%' followed by their two-digit hexadecimal representation. This ensures that browsers and servers interpret the data correctly without confusing data characters with URL delimiters like the question mark or ampersand.
Best Practice
Never include sensitive data like passwords in URL query parameters, even if they are encoded.
encodeURIComponent() and decodeURIComponent() for dynamic URL building.Q: What characters are typically encoded? A: Reserved characters such as space, ?, &, =, and # are encoded to prevent them from being interpreted as part of the URL syntax.
Q: Is URL encoding the same as Base64? A: No, URL encoding uses percent signs for special characters, while Base64 converts data into a specific 64-character alphabet for binary data.
Q: When should I use this tool for debugging? A: Use it when you see strings like '%20' or '%3D' in a URL and need to know the original text for troubleshooting.
