FAQ
Frequently Asked Questions
When should I encode a URL?
Encode URLs when they contain special characters, spaces, or non-ASCII characters. Essential for query parameters, API requests, and cross-browser compatibility.
What's the difference between encoding and decoding?
Encoding converts special characters to percent-encoded format (e.g., space → %20). Decoding reverses this, converting %20 back to a space.
Does this support UTF-8 characters?
Yes! Full UTF-8 support allows encoding and decoding of URLs with international characters, emojis, and other Unicode symbols.
What is percent-encoding?
Percent-encoding (URL encoding) is a mechanism in RFC 3986 for encoding information in a URI. Special characters are replaced by a '%' followed by two hexadecimal digits.
