FAQ

Does this send my URL data to a server?

No. This tool processes the text in your browser and does not upload the input value to the server.

What is URL encoding used for?

URL encoding converts reserved characters, spaces, and symbols into a web-safe format for query parameters and links.

Why does decode sometimes fail?

Decode can fail when the input is incomplete or not valid percent-encoded text.
