URL Encoder

Encode and decode URL components and query strings. Free online developer tool for fast browser-based work.

What is this tool?

URL Encoder converts reserved characters into a URL-safe form and decodes encoded URLs back to readable text. It helps avoid broken query strings, callback URLs and copied request examples.

How to use

Paste the full value or parameter that needs to travel inside a URL.
Encode before placing dynamic text inside a query string, redirect URL or cURL command.
Decode existing URLs when you need to read parameters during debugging.

Encoded

Practical example

URL encoding keeps spaces, accents and reserved characters from breaking query parameters.

Input:
https://example.com/search?q=café com leite

Output:
https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dcaf%C3%A9%20com%20leite

API

Make request examples clearer and reproducible.

Privacy

URLs can contain tokens or private identifiers. Remove secrets and personal data before sharing encoded or decoded examples.

Frequently asked questions

When should I URL encode text?

Encode text when it becomes part of a query parameter, path segment, redirect URL or request example.

Why did my ampersand break the query string?

An unencoded ampersand separates parameters. Encode it when it is part of the value itself.

Is URL encoding a security feature?

No. It improves transport compatibility. It does not hide or protect sensitive values.

Limitations / when not to use

Encoding a full URL and encoding one parameter are different tasks. Use component encoding for parameter values so separators such as ? and & keep their intended meaning.
