Frequently Asked Questions

Which characters get encoded?

Spaces, accented characters, and any character with special meaning in a URL (like ?, &, =, #) are encoded per the standard rules.

What happens if I enter invalid encoded text?

You'll see a clear error message for data that can't be decoded.

Should I encode the whole URL or just part of it?

Usually you only need to encode query parameter values; encoding the whole URL can break the protocol and domain.

Is my data sent to a server?

No, everything happens locally in your browser.
