URL Encode Tool

Stop Breaking Your Links: Percent-Encoding Made Easy

Malformed URLs are the silent killers of web applications and marketing campaigns. If your query strings contain spaces, ampersands, or non-ASCII characters that aren't properly escaped, servers will reject them, and APIs will throw errors. Our URL Encode Tool fixes this instantly.

Using the industry-standard encodeURIComponent method, we transform unsafe characters into the "percent-encoded" format (e.g., spaces become %20). Unlike server-side tools that log your data, our converter operates 100% client-side. This guarantees that your sensitive API keys, UTM parameters, and data payloads never leave your browser.

How to Encode URL Parameters

1. Paste: Input your target string (e.g., a search query like c++ tutorial) into the text box.
2. Encode: Click the primary button to trigger the conversion algorithm.
3. Copy: The tool generates the safe string (c%2B%2B%20tutorial) for you to copy and deploy.

Frequently Asked Questions About URL Encode

What is URL encoding?

URL encoding (or percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits, ensuring that data can be transmitted over the internet without being misinterpreted by browsers.

How do you encode a URL?

Input your string into the text box above and click "Encode." The tool converts unsafe characters (like spaces and ampersands) into percent-encoded entities (like %20 and %26) suitable for inclusion in browser address bars.

Why is URL encoding necessary?

URLs have a strict set of allowed characters. Reserved characters like ?, /, and # have special structural meanings. To include these characters as data (e.g., inside a query parameter), they must be encoded so the server treats them as text rather than a command.

What characters are allowed in a URL without encoding?

The "unreserved" characters include alphanumeric characters (A-Z, a-z, 0-9), hyphens (-), underscores (_), periods (.), and tildes (~). Almost all other characters require percent-encoding to be universally safe.

What is an example of a URL encoded string?

If you need to pass the email [email protected] in a URL, it must be encoded to user%2Btest%40example.com. Without encoding, the + might be interpreted as a space by some servers, corrupting the data.
