100% Private & Secure
ToolNGame is designed with a "Privacy First" philosophy. This URL Encoder/Decoder runs entirely in your browser using local JavaScript. Your files and data are never uploaded to our servers, ensuring your sensitive information stays exactly where it belongs—on your device.
How to use URL Encoder/Decoder?
Paste your URL or text
Enter a complete URL or plain text you want to encode for safe transmission in URLs.
Choose encoding type
Select between standard URL encoding (application/x-www-form-urlencoded) or component encoding for URI components. The tool auto-detects input type.
Copy the encoded result
Copy the result and use it in query parameters, form data, or API calls. Decoded output is immediately visible.
Frequently Asked Questions
What is URL encoding?
URL encoding (percent encoding) converts unsafe characters into a %XX format where XX is the character's hexadecimal ASCII value. Example: space becomes %20, & becomes %26. Essential for safe URL transmission.
When do I need URL encoding?
Encode when passing user input in URLs (query parameters), form data, or API requests. Unencoded special characters can break URLs or cause security issues.
What's the difference between encoding and component encoding?
Standard encoding encodes the full URL. Component encoding treats the input as a URL part (query value) and encodes more aggressively. Use component for query parameters, standard for full URLs.
Why is & encoded to %26 in URLs?
The & character separates query parameters (e.g., ?key1=value&key2=value). If your value contains &, it must be encoded as %26 to avoid being mistaken for a parameter separator.
Are spaces encoded as + or %20?
Both are valid. %20 is standard URL encoding for space. The + sign is an alternative used mainly in application/x-www-form-urlencoded data (HTML form submissions). Modern APIs prefer %20.
How do I encode international characters?
International characters are first converted to UTF-8 bytes, then each byte is percent-encoded. Example: é (UTF-8: C3 A9) becomes %C3%A9. Browsers handle this automatically.
Can I decode an encoded URL back?
Yes. Simply paste the encoded URL or text and use the decoder. The tool auto-detects encoded input and reverses the process, restoring the original characters.
Which characters must be encoded?
Non-alphanumeric characters (except - _ . ~) must be encoded. Special focus: space, &, =, ?, #, @, /, and non-ASCII characters. Unreserved characters (a-z, A-Z, 0-9, hyphen, underscore, dot, tilde) never need encoding.
