Frequently Asked Questions About URL Encoder and Decoder

Find answers to common questions about URL encoding and decoding

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts characters into a format that can be transmitted over the Internet, as URLs can only use the ASCII character set. Non-alphanumeric characters and those with special meanings in URLs are replaced with a "%" followed by two hexadecimal digits.
URLs can only contain certain characters from the ASCII set. When you have characters outside of this set, or characters that have special meanings in URLs (like #, ?, &, =, etc.), they need to be encoded to ensure the URL is valid and can be transmitted correctly over the internet. Encoding prevents these characters from being misinterpreted by web servers.
Spaces in URLs can be encoded in two ways: as + or as %20. The + symbol is a legacy encoding method that was commonly used in query strings, while %20 is the more standard percent-encoding. Both are valid, but %20 is generally preferred for consistency and clarity.
