About the URL Encoder
Encode text for safe use in URLs and query strings.
URL Encoder converts special characters in text to percent-encoded format (%20, %3D, %26) safe for use in URLs, query strings, and API requests. Paste any text and get the encoded version — essential when building links with spaces, ampersands, or non-ASCII characters.

Frequently asked questions
Spaces, &, =, ?, #, %, +, and non-ASCII characters all need encoding in URLs. Letters (a-z, A-Z), digits (0-9), and -_.~ are safe and never encoded. Everything else gets percent-encoded.
encodeURI encodes a full URL but keeps :, /, ?, & intact. encodeURIComponent encodes everything except letters and digits — use it for individual query parameter values. This tool uses encodeURIComponent.
Both are valid. %20 is the standard percent-encoding. + is only valid in query strings (application/x-www-form-urlencoded). In URL paths, only %20 works. This tool uses %20 for maximum compatibility.
Double-encoding can break links — encoding an already-encoded string turns %20 into %2520. Always encode raw text, not already-encoded URLs. This tool works on raw input only.
