URL Encoder / Decoder

How to Encode and Decode URLs with FreeToolPoint

1. Enter your text or URL — Paste or type the URL, query parameter, or text string you need to encode or decode into the input field. This can be a full URL with special characters, a query string value, or any text containing characters that need URL-safe encoding.
2. Click Encode or Decode — Click Encode to convert special characters into their percent-encoded equivalents (for example, spaces become %20). Click Decode to convert percent-encoded strings back to their original readable form.
3. Review the output — The encoded or decoded result appears in the output area below. The encoding follows the standard encodeURIComponent specification, which is safe for use in URL query parameters, form data, and API requests.
4. Copy the result — Click Copy to copy the output to your clipboard. Paste it directly into your URL, API request, code, or wherever you need the encoded or decoded value.

Why Use Our URL Encoder/Decoder

• Standards-compliant encoding — Uses JavaScript's encodeURIComponent and decodeURIComponent functions, which follow the RFC 3986 standard. This ensures your encoded URLs are compatible with all web servers, browsers, and API endpoints.
• Full Unicode support — Correctly handles international characters, emojis, and any Unicode text. Multi-byte characters are properly encoded as UTF-8 byte sequences, ensuring compatibility across all systems and languages.
• Instant results — Encoding and decoding happen instantly in your browser with no server calls. There are no size limits, no rate limiting, and no account requirements. Process as much text as you need.
• Complete privacy — Your URLs and text data never leave your browser. This is important when working with URLs that contain API keys, authentication tokens, or other sensitive query parameters.

Understanding URL Encoding

URL encoding (also called percent encoding) is the process of converting characters that are not allowed in URLs into a format that can be safely transmitted. URLs can only contain a limited set of characters from the ASCII character set. Characters like spaces, ampersands, question marks, and non-ASCII characters must be percent-encoded to be included in a URL.

For example, a space character is encoded as %20, an ampersand becomes %26, and a question mark becomes %3F. Unicode characters like accented letters or Asian scripts are first converted to their UTF-8 byte representation, and then each byte is percent-encoded. The character "cafe" with an accent on the e would be encoded as "caf%C3%A9".

URL encoding is essential when building query strings, submitting form data, constructing API requests, or embedding user-generated content in URLs. Failing to properly encode special characters can cause broken links, incorrect data transmission, and security vulnerabilities like injection attacks. Always encode user input before including it in a URL to ensure both functionality and security.
