Free URL Encoder and Decoder
Encode text so it is safe to use in a URL, or decode a messy encoded URL back into readable text. Useful for UTM links, WhatsApp messages, Hindi URLs and API work.
How to use the URL encoder and decoder
- Choose Encode or Decode.
- Paste your text or URL.
- When encoding, pick “a value” for a single parameter, like a WhatsApp message, or “a full URL” to keep the slashes and question mark.
- Copy the result.
What is URL encoding?
URLs can only contain a limited set of characters. Spaces, Hindi letters, emojis and symbols like & or # have to be converted into percent codes, such as %20 for a space. This is called percent encoding. Browsers do it automatically, but when you build links by hand, for example for ads, emails or WhatsApp, you often need to do it yourself.
Common encoded characters
| Character | Encoded |
|---|---|
| Space | %20 |
| & | %26 |
| , | %2C |
| ? | %3F |
| # | %23 |
| Hindi letter क | %E0%A4%95 |
Where marketers use it
- Pre-filled WhatsApp messages in wa.me links. Our WhatsApp link generator does this for you.
- UTM values with spaces or symbols. The UTM link builder encodes them automatically.
- Reading messy links from reports and analytics, where Hindi page names show up as long percent codes.

Frequently Asked Questions
Is this URL encoder free?
Yes. It is free with no sign-up and runs in your browser.
What is the difference between encoding a value and a full URL?
Encoding a value converts every special character, which is right for a single parameter. Encoding a full URL keeps characters like slashes, colons and question marks so the link still works.
Why does my decoded text show an error?
The text probably has a percent sign that is not followed by two valid hex digits. Check for a broken or cut-off link.
Should spaces be %20 or +?
In URL paths use %20. In query strings, + is also commonly read as a space, which is why decoding treats + as a space by default.
