Frequently Asked Questions
A URL encoder converts special characters that cannot be included in URLs (spaces, non-ASCII characters, &, = etc.) to percent encoding (%XX).
This tool uses encodeURIComponent, which is suitable for encoding individual values rather than entire URLs.
Non-ASCII characters are percent-encoded on a UTF-8 byte basis. Example: a space becomes %20.
Both standard URLs and query strings (key=value&...) are supported.
No. All encoding/decoding is processed in the browser.
