URL Decoder
Runs entirely in your browser

Features

Frequently Asked Questions
Is my text uploaded to a server?
No. URL Decoder runs entirely in your browser. Your text never leaves your device.
What does URL decoding do?
It converts percent-encoded sequences like %20 or %26 back into their original characters — a space or & in those examples.
Does this handle + as a space?
No. Plus-as-space is a convention specific to form encoding (application/x-www-form-urlencoded), not standard percent-encoding, so + is left as-is. Use a query-string-specific tool if you need that behavior.
What happens if the input isn't valid percent-encoding?
You'll see a clear error message instead of a page crash or garbled output — fix the input and try again.
