FAQ

Frequently asked questions

3 answers

Can I encode a full URL?

Yes, but encoding a whole URL will escape separators too. For query parameter values, paste only the value you want encoded.

Why does decoding fail?

The input may contain malformed percent-encoded sequences.

Does this open the URL?

No. It treats input as plain text only.
