Frequently asked questions
When should I encode a URL?
Whenever a value with spaces or symbols goes into a link or query string.
What is the difference between component and full URL mode?
Full URL mode keeps characters like : / ? & = intact; component mode encodes them.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
