Frequently Asked Questions
What is URL encoding?
URL encoding, also called percent encoding, replaces unsafe characters in a URL with a percent sign followed by two hexadecimal digits representing the character's byte value. For example, a space becomes %20 and an ampersand becomes %26.
When should I use URL encoding?
Use URL encoding whenever you need to include special characters in URLs, query parameters, form data, or any context where certain characters have reserved meanings. Common cases include passing user input in query strings and encoding file names with spaces.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URI but preserves characters that have special meaning in URLs like /, ?, #, and &. encodeURIComponent encodes everything except unreserved characters (letters, digits, hyphens, underscores, periods, and tildes), making it the right choice for encoding individual parameter values.
