Frequently Asked Questions
`encodeURIComponent` encodes more characters (including `&`, `=`, `?`) and is safe for query parameter values; `encodeURI` is for encoding a full URL and leaves those characters untouched.
When you've received an already-encoded URL or query string and need to read the actual, human-readable value inside it.
Yes — encoding converts non-ASCII characters (like accented letters or non-Latin scripts) into their percent-encoded byte representation, which is required for them to work reliably in a URL.
No — encoding and decoding both happen entirely in your browser.
You'll get a clear error message rather than an incorrect or garbled result.

About URL Encoder / Decoder
URL Encoder / Decoder converts text and URLs to and from percent-encoded format — needed whenever special characters (spaces, `&`, `=`, `?`, non-English characters) have to be safely included in a URL or query string without breaking it. Both `encodeURIComponent` and `encodeURI` modes are supported, since the correct encoding depends on whether you're encoding a full URL or just one value within it.
