About this URL Encode

URL Encode converts special characters into percent-encoded sequences so the text can be safely used in URLs and query parameters.

This is useful when building links, working with query strings, or pasting values into APIs. If you only need to encode a query value, encodeURIComponent-style behavior is usually preferred.

FAQ

Is my text uploaded to a server?

No. Everything runs locally in your browser. Nothing you paste is sent to a server.

Can I use this tool offline?

After the page loads once, it will typically keep working offline (unless you hard refresh with no cache).

Do you store my input?

No. Your input stays in your browser. Only optional preferences like theme or language may be stored.

What input formats are supported?

Any plain text. You can paste text directly into the input box.

What does URL encoding do?

It converts characters like spaces and symbols into %XX sequences so they are safe in URLs.

Should I encode a full URL or just a parameter value?

Most of the time you should encode parameter values. Encoding a full URL may also encode : and /.

Why do spaces become %20?

Spaces are not always safe in URLs. %20 is the standard percent-encoded representation.
