About this Tool

Securely completely encode and decode URL string parameters.

1Why Encode URLs?

URLs are restricted to a specific set of ASCII characters. If your URL path or query parameters contain spaces, non-ASCII characters, or reserved symbols (like `&` or `=`), they must be "Percent Encoded" to ensure they are correctly interpreted by web servers and browsers.

2Example: Percent Encoding

Input URL: `https://example.com/search?q=hello world` Encoded URL: `https://example.com/search?q=hello%20world`

3Safe Character Handling

Our tool distinguishes between the full URI and URI components, correctly preserving structural characters like `://` when necessary, or encoding everything for safe use as a query parameter value.

4Privacy: Local URL Parsing

URL parameters often contain session IDs, user emails, or tracking tokens. By performing all encoding and decoding directly in your browser, we ensure that your sensitive navigation history and query data are never exposed to any third-party analytics or logging servers.

Privacy Guarantee

Secure Devutils operates exclusively in your browser using local web workers and JavaScript. Your source code, configurations, and sensitive text payloads are never transmitted across the network or stored on any external servers. It is completely safe for air-gapped environments.
