People also ask
What characters get encoded?
All characters outside the unreserved set (A-Z, a-z, 0-9, hyphen, underscore, period, tilde) are converted to their percent-encoded form, such as %20 for spaces.
Does it encode the entire URL or just the query string?
You can encode any string. For full URLs, it is best to encode only the parameter values rather than the entire URL to avoid breaking the protocol and path structure.
Does it handle Unicode characters like emojis or accented letters?
Yes, Unicode characters are encoded using UTF-8 byte sequences (e.g., %C3%A9 for 'é').
What is the difference between encodeURI and encodeURIComponent behavior?
This tool uses full component encoding (equivalent to encodeURIComponent), which encodes all special characters including /, ?, and &.
Is this tool free?
Yes, the URL encoder/decoder is free to use with no limits.

Why use this tool?
Improperly encoded URLs cause broken links, failed API requests, and data corruption in query parameters. This URL encoder/decoder ensures your URLs and query strings are correctly formatted for web browsers, APIs, and HTTP requests.

URL Encoder — In-Depth Guide
URL encoding converts special characters into percent-encoded sequences safe for use in web addresses. Spaces become %20, ampersands become %26, and other reserved characters are escaped to prevent them from being misinterpreted as URL delimiters. This is essential when constructing query strings with user-provided data.
Web developers encode URL parameters to prevent injection attacks and ensure links work correctly. A search query containing special characters like question marks or hash symbols would break the URL structure without proper encoding. Form data submitted via GET requests must be URL-encoded to reach the server intact.
API developers encode request parameters when constructing URLs programmatically. OAuth signatures, webhook URLs, and callback parameters frequently require double-encoding to survive multiple levels of URL parsing. Understanding URL encoding prevents subtle bugs where parameters are silently truncated or misinterpreted by intermediary servers.
When debugging web applications, decoding URL-encoded strings reveals the original text hidden behind percent sequences. This is useful when examining browser network requests, server logs, and error messages that display encoded URLs. A quick decode confirms whether the correct parameters were sent in API calls and form submissions.
