URL Encoding Guide
What Is a URL Encoder?
A URL Encoder converts characters into a percent-encoded representation that can be safely used in URLs and URI components. Characters are represented with a percent sign followed by hexadecimal byte values when encoding is required.
URL encoding is commonly used for query parameter values, path data, redirect URLs, API requests and text containing spaces, symbols or non-ASCII characters.
URL Encoding Example
Original text:
Hello World & moreEncoded component:
Hello%20World%20%26%20moreWhy Encode URLs?
URLs use certain characters as structural delimiters. Encoding helps represent spaces, Unicode text and characters that could otherwise be interpreted as part of URL syntax.
The correct encoding strategy depends on context. A complete URI and an individual query parameter value should not always be encoded in exactly the same way.
How Does Percent Encoding Work?
Percent encoding represents encoded bytes using a percent sign followed by two hexadecimal digits. For example, a space is commonly represented as %20 in URI encoding.
Unicode text is first represented as UTF-8 bytes and those bytes are then percent encoded where required.
encodeURI vs encodeURIComponent
Full URI Mode uses JavaScript's encodeURI behavior and preserves many URL structural characters such as colons, slashes, question marks and ampersands.
Component Mode uses encodeURIComponent behavior and encodes more reserved characters. It is generally appropriate for individual parameter values or URI components rather than an entire URL.
Common Uses for URL Encoding
Query Parameters
Encode parameter values containing spaces, symbols or Unicode text.
API Requests
Prepare dynamic values for URL-based API endpoints and requests.
Redirect URLs
Represent nested URLs safely inside redirect and callback parameters.
International Text
Encode multilingual and Unicode content for URI-compatible transport.
