URL Encoder & Decoder
Convert special characters into URL format (Percent-encoding) for stable web transmission or decode encoded strings back to readable text.
Why Do URLs Need Percent-Encoding?
URLs are only allowed to contain a small set of characters from the ASCII character set. Reserved characters that have special meaning (like ?, &, and =) or unsafe characters (like spaces and emojis) must be "encoded" to ensure they are transmitted correctly by web browsers and servers.
Common URL Encoding Reference
| Character | Reason for Encoding | Encoded Value |
|---|---|---|
| Space | Used to separate parts of a URL | %20 |
| ! | Reserved character | %21 |
| # | Identifies a fragment in a URL | %23 |
| $ | Reserved character | %24 |
| & | Used to separate query parameters | %26 |
How to Use This Tool
- Encode: Paste your plain text or full URL to make it "web-safe".
- Decode: Paste a string containing
%codes to reveal the original readable text. - Privacy: We never log your URLs. All processing happens locally in your browser.
