Encode or decode URLs and text instantly — all in your browser.
URL encoding (also called percent-encoding) converts characters into a format that can be safely transmitted over the internet. Special characters like spaces, &, ?, =, and non-ASCII characters must be encoded because they have special meanings in URLs or are not allowed.
Each encoded character is replaced by a % followed by two hexadecimal digits. For example, a space becomes %20.
| Character | Encoded |
|---|---|
| Space | %20 |
| @ | %40 |
| & | %26 |
| ? | %3F |
| = | %3D |
| + | %2B |
| # | %23 |
URL decoding is the reverse process: it converts percent-encoded strings back into human-readable text. This is useful when you receive an encoded URL and need to understand its parameters or content.
For example, %20 becomes a space, %40 becomes @, and so on. Decoding helps debug APIs, fix broken links, and read query strings.
URL encoding converts characters into a percent-encoded format so they can be safely transmitted in a URL.
It prevents ambiguity and errors when URLs contain spaces, special characters, or non-ASCII text.
Reserved characters like :/?#[]@!$&'()*+,;= and any non-alphanumeric characters are typically encoded.
Yes, decoding reverses encoding perfectly, as long as the encoded string is valid.
URL encoding is for making text URL-safe, while Base64 encodes binary data into ASCII. They serve different purposes.
Whenever you include dynamic values in a URL, like query parameters or path segments.
Yes, but be careful not to encode the scheme (https://) and domain if you plan to use it directly. Usually only parts are encoded.
No. Everything runs in your browser using JavaScript. No data is sent to any server.
