Why you might need a URL encoding tool
URL encoding is something developers and web designers need often, especially when a URL or parameter contains special characters, spaces, or Arabic letters, since URLs are only allowed to use a limited set of characters and symbols. The tool lets you encode or decode any text in a second without writing any code yourself.
How URL encoding (Percent-Encoding) works
URL encoding follows a standard called Percent-Encoding, and it converts any character not allowed in a URL (like spaces, special symbols, or non-Latin letters) into a sequence starting with a % sign followed by two hexadecimal digits representing the character's value. For example, a space becomes %20, and the & symbol becomes %26. Decoding does the reverse, turning the encoded sequences back into the original, readable text.

Practical Tips Before You Start
Before you start, keep these points in mind:
- If your URL has multiple parameters separated by &, make sure you encode each parameter's value individually, not the whole URL at once, so the URL's core structural symbols don't get encoded incorrectly.
- Regular English letters and digits don't need encoding in the first place, so they stay unchanged after encoding.
- If the text contains Arabic letters, you'll notice each character turns into more than one %XX sequence because of how UTF-8 encoding works.
- Use decoding if you want to read a complicated-looking URL full of % symbols.
Your privacy is fully protected; none of the data you enter is saved or stored.
Common use cases
- Encoding search parameters or filters inside a website or app URL.
- Decoding complex URLs to read the original value inside them.
- Preparing links containing Arabic text or characters so they work correctly across all browsers.
- Encoding simple data before sending it as part of an API or webhook URL.

Frequently Asked Questions
What's the difference between URL encoding and Base64 encoding?
URL encoding (Percent-Encoding) is meant to make text valid for use inside a link, while Base64 is a general method for converting any binary data into text — each has a different purpose.
Does the tool support Arabic text?
Yes, you can encode or decode any text, including Arabic characters, without any issues.
Why does a space sometimes become + and sometimes %20?
Both are correct depending on the context; %20 is the general standard for URL encoding, while + is used specifically for encoding application/x-www-form-urlencoded form data.
Is the tool free and without sign-up?
Yes, you can use it for free without creating an account.
Is my data stored with you when I use the tool?
No, all encoding or decoding happens directly inside your browser, and no text is stored or sent to any server.
