The easiest way to format URLs. Encode special characters, fix broken links, and ensure safe data transmission instantly.
URL Encoding (or Percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL, or have special meaning (like ?, &, /, or #), must be converted into a safe format to be transmitted correctly over the internet.
%20 ensures they work everywhere.?query=hello world), it must be encoded to prevent browser errors.| Character | Encoded | Description |
|---|---|---|
| Space | %20 | The most common issue in URLs. |
| / (Forward Slash) | %2F | Used to separate directories. |
| ? (Question Mark) | %3F | Indicates the start of query parameters. |
| & (Ampersand) | %26 | Separates multiple query parameters. |
Simple, fast, and standard compliant.
Our tool uses the standard JavaScript `encodeURIComponent()` function, which adheres to RFC 3986. This ensures your URLs are compatible with all modern browsers and servers.
Works on all platforms.
This tool uses `encodeURIComponent`, which encodes special characters including `/`, `?`, and `&`. This is safer for encoding values inside a query parameter. `encodeURI` assumes you are encoding a full URL and leaves structural characters alone.
Yes. Emojis and non-ASCII characters are encoded using UTF-8 sequences before being percent-encoded.
