๐ URL Encoder / Decoder
URL Encoder/Decoder applies standard percent-encoding (RFC 3986, via the browser's native encodeURIComponent) and decodes it back, with full UTF-8 support, live as you type. Use it before putting user text into query strings, and to decode those cryptic redirect URLs when debugging. Everything runs locally.

|---|---|---|
| A query parameter value | Encode component | &, = and ? get escaped |
| A full URL you want to pass along | Encode (whole URL) | Keeps :// and separators intact |
| Spaces in a search term | Encode component | Becomes %20, link survives |
| Non-Latin characters | Either โ UTF-8 safe | Emoji and ไธญๆ encode correctly |
| A % that is not valid escape | Decode fails | Garbage in, error out |
| Plus signs for spaces | Decode treats + literally | Form-style encoding differs |

Detailed User Guide
Encode text for safe URLs
Encoding replaces reserved and non-ASCII characters with percent-encoded equivalents, so a string can be safely placed in a URL or query string.
Decode percent-encoded URLs
Decoding reverses the process, turning %20 back into a space and other codes into their original characters, making URLs readable.
Prevents broken links and query strings
Unencoded spaces and symbols break URLs and API requests. Encoding them first is a basic step in building correct links.
Local processing, nothing uploaded
Your strings stay in the browser, which matters when encoding API keys or internal endpoints.
Handles full UTF-8 characters
Non-ASCII characters like emoji and accented letters are encoded correctly, so they survive transmission in URLs.
Encode only the unsafe parts
In a full URL, encode the query-string values rather than the entire address, so the scheme and slashes stay intact and the link still resolves correctly.
Encoding spaces and special symbols
Spaces become %20 (or + in form data) and symbols like & and = are escaped, so query parameters pass through correctly without being mistaken for URL syntax.
