URL Encoder / Decoder

Encode plain text into percent-encoded URL strings or decode encoded URIs back into readable text securely in your browser.

🔒 Client-Side Processing: URL strings are transformed instantly within your browser sandbox.

How URL Encoding Works

URLs often contain special characters (such as spaces, ampersands, or question marks) that must be percent-encoded to prevent parsing errors in web requests. Our browser-based URL Encoder translates your query strings and links locally on your device.
