Free URL Encoder & Decoder Online

URL encoding converts special characters like spaces, ampersands, equals signs, and question marks into a format that is safe to place inside URLs, API parameters, and HTML attributes. Without it, these characters can break a link or cause a request to be interpreted incorrectly by servers and browsers.

URL Encode converts readable text into percent-encoded format that is safe for URLs, while URL Decode converts that percent-encoded text back into readable form. You encode before sending data in a link and decode when you want to read or debug an encoded URL someone shared with you.

Yes. Paste your query string parameter values and encode them so they transmit safely in URLs. As a best practice, encode each value separately rather than the whole URL, so the structural characters like slashes, colons, and the question mark stay intact and the address remains valid.

In JavaScript, encodeURI keeps characters that form a URL structure (like / : ? &) intact and is meant for whole URLs, while encodeURIComponent encodes those characters too and is meant for individual parameter values. Use component encoding for query values and full-URI encoding only when encoding a complete address.

No. Percent encoding only makes characters safe to place in a URL; it does not encrypt or hide anything. Anyone can decode the value just as easily as you encoded it. Never use URL encoding as a security measure for passwords, tokens, or sensitive information. Use proper encryption and HTTPS for that.

In the path of a URL a space is encoded as %20. In query strings, the older form-encoding standard represents a space as a plus sign instead. Both are valid in their context. Helperzy uses standard percent encoding, and decoding handles both forms so you read the original text correctly.

Yes, but you may need to decode it more than once. If a URL was encoded twice, a single decode leaves you with a once-encoded string, so just run Decode again on the result until the text is fully readable. Double encoding sometimes happens when a link passes through several systems.

There is no strict character limit in the tool itself, so you can encode long query strings or whole URLs comfortably. Keep in mind that browsers and servers often limit total URL length to around 2,000 characters, so very long encoded results may need to be shortened or sent in the request body instead.
