Does this encode the whole URL?
It applies encodeURIComponent-style encoding, which is best for query values and text fragments.
Why are spaces converted to %20?
Percent-encoding represents spaces as %20 so the value can travel safely inside a URL.
Can I use this as a URL space encoder?
Yes. Paste text or a URL value with spaces, then encode it. Spaces become %20 and other unsafe characters are encoded too.
Why do some strings need decoding twice?
Some systems encode values more than once. This tool decodes one layer each time you run it.
Is my data uploaded to a server?
No. The tool runs in your browser, so the text you paste stays on your device.
