When should I URL encode?

You should URL encode when passing special characters in query parameters, form data, or path segments. Characters like spaces, &, =, ?, #, and non-ASCII characters must be encoded to avoid breaking the URL structure.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URI but preserves characters like :, /, ?, and #. encodeURIComponent encodes everything including those characters, making it suitable for encoding individual query parameter values.

Is URL encoding the same as Base64 encoding?

No. URL encoding (percent-encoding) makes strings safe for URLs by replacing special characters with %XX sequences. Base64 encoding converts binary data to ASCII text. They serve different purposes.

What Is URL Encoding?

URL encoding, also known as percent-encoding, is a mechanism for encoding special characters in URLs. Characters that are not allowed in URLs (spaces, &, =, etc.) are replaced with a percent sign followed by their hexadecimal ASCII value. For example, a space becomes %20 and an ampersand becomes %26.
