What is Url Encode/Decode?

URL encoding and decoding, both methods use to convert special characters or non-ASCII characters in a URL into a format that can transmit over the Internet. Our free URL Encoder / Decoder is an online tool that will help to encode or decode the URL.

URL Encoding is the process of converting characters into a format that can transmit over the internet. This often ensures that URLs do not contain any characters that web servers or web browsers may misinterpret or reject. URL encoding replaces unsafe characters with a percentage sign followed by a two-digit hexadecimal value. For example, the space character encodes as %20 in URL encoding.

URL Decoding is the process of converting a URL-encoded string back into its original form. You can decode any URL-encoded characters by replacing them with their corresponding character values. For example, you would decode %20 in a URL-encoded string to a space character.

URL encoding and decoding, both use in web applications to transmit data between a client and server. For example, when transmitting data through a form or API, the system often encodes the data in URL format before sending it, and the receiving end decodes it upon receipt.

What are Reserved characters?

The “reserved” set includes characters that delimit components and subcomponents in URIs. These characters refer to as “reserved” because they may or may not define as delimiters (gen-delims & sub-delims) by the generic syntax, scheme-specific syntax, or implementation-specific syntax of a URI’s dereferencing algorithm. If any data for a URI component conflicts with the reserved character’s purpose as a delimiter, then the conflicting data must be percent-encoded before forming the URI.

gen-delims  = : / ? # [ ] @

sub-delims  = ! $ & ' ( ) * + , ; =

What are Unreserved characters?

Unreserved characters in a URI permit the usage of specific characters for no particular purpose. These characters comprise both uppercase and lowercase letters, decimal digits, hyphens, periods, underscores, and tildes.

Unreserved  = ALPHA DIGIT - . _ ~
