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.
