URL Encode & Decode Online
URLs can only contain certain ASCII characters. Spaces, special characters, and non-ASCII characters must be percent-encoded (e.g., a space becomes %20) to be valid in web addresses. Our URL encoder/decoder tool converts text to URL-safe format and decodes percent-encoded URLs back to readable text. Essential for building query strings, debugging redirects, and working with web APIs.

Spaces, ampersands (&), question marks (?), equals signs (=), hash (#), percent (%), and non-ASCII characters all need to be percent-encoded in URLs.
encodeURI encodes a full URI but preserves characters like :, /, and ?. encodeURIComponent encodes everything except letters, digits, and a few special characters. Use encodeURIComponent for query string values.
In URLs, spaces are encoded as %20. In HTML form data (application/x-www-form-urlencoded), spaces can also be represented as +. Both are valid depending on context.
