Frequently asked questions
Is this URL decoder free?
Yes. You can decode unlimited text for free, with no sign-up required.
What happens if the input is invalid?
You'll see a clear message that the input isn't valid percent-encoded text, instead of a cryptic error.
What format does it expect?
The same encoding produced by JavaScript's encodeURIComponent() (and this site's URL Encoder) — sequences like %20 for a space.
Is my data sent to a server?
No. Decoding happens locally in your browser using native JavaScript APIs.
