Pourquoi utiliser cet outil

Convert raw text into URL-safe strings or decode encoded values back into readable text.

URL Encoder handles percent-encoding directly in the browser.

It is useful when debugging parameters, sharing links, or preparing query values.

01Paste a raw value or an encoded value into the text area.

02Copy the encoded or decoded result you need.

Confirm the input is the format you intended.

Scan the result before using it in a document, URL, config, or message.

Copy only the output you need.

What happens if the encoded string is invalid?

The decoded panel falls back to an empty value.

Does it encode the entire URL or just a value?

It encodes the input as a value. For full URLs, encode only the query parameter values, not the base URL.

What characters are left unencoded?

Letters, digits, and the characters - _ . ! ~ * ' ( ) are left as-is. Everything else is percent-encoded.

Decode URL/Base64 payloads, normalize JSON, and inspect timestamps from one debugging workspace.

Convert plain text to Base64 and back.
