🔗 URL Encoder / Decoder

All encoding and decoding happens instantly in your browser — nothing is sent to any server. Use encodeURIComponent for query string values, encodeURI for full URLs, and Base64 for binary-safe text encoding.

How to encode or decode a URL

Pick your mode, paste your input, and copy the result — done in seconds.

01
Choose encode or decode
Select Encode to convert special characters to percent-encoded form, or Decode to convert them back to readable text.
02
Paste your URL or string
Paste the URL, query string, or text you want to process. The tool handles the full URL or just a component.
03
Pick the encoding type
Use encodeURIComponent for query parameters and path segments. Use encodeURI for full URLs. Use Base64 for binary-safe encoding.
04
Copy the result
Copy the encoded or decoded output and use it in your code, browser address bar, or API request.

When you need to encode or decode a URL

A query parameter breaks the URL

Values like &, =, and spaces in query strings need encoding or the URL parser splits them incorrectly. Encode the value before appending it.

An API response has percent-encoded URLs

APIs sometimes return encoded paths. Decode them to read the actual route and parameter values without squinting at %2F and %3D.

A redirect URL contains another URL

When a redirect target is itself a URL parameter, the inner URL must be encoded so the outer parser doesn't treat its ? and & as its own.

Inspecting a form submission payload

HTML forms encode data as application/x-www-form-urlencoded. Decode the payload to see exactly what was submitted.

A webhook arrived with encoded characters

Webhook endpoints often arrive with percent-encoded paths. Decode to see the original route and parameters.

Sharing a link with spaces or special characters

A URL with spaces or accented characters breaks in some email clients and messaging apps. Encode it first.

Frequently asked questions

Free, no account, no limits.

Nothing is sent anywhere. Encoding and decoding run entirely in your browser.

encodeURI encodes a full URL and leaves characters like /, ?, and # intact. encodeURIComponent encodes everything except letters, digits, and - _ . ~ — use it for individual query parameter values.

Percent encoding replaces unsafe characters with a % followed by two hex digits. A space becomes %20, & becomes %26, and so on.

In application/x-www-form-urlencoded (HTML form data), spaces are encoded as +. In standard URL encoding, spaces are %20. Both are valid in their respective contexts.

Yes. Paste the full URL and use encodeURI mode to encode only the characters that are unsafe in a URL while leaving the structure intact.

Yes, in any modern mobile browser.
