Frequently Asked Questions
When should I encode a URL?
Encode URLs when passing them as query parameters or when the URL contains spaces, brackets, or other characters not allowed in raw URL syntax.
What is the difference between full URL and component encoding?
Full URL encoding preserves the URL structure (/, ?, #, =). Component encoding encodes those structural characters too: use it for individual parameter values.
Is any data sent to a server?
No. All encoding and decoding runs in your browser.
What does percent-encoding mean?
Percent-encoding replaces unsafe characters with a % sign followed by two hexadecimal digits, e.g. a space becomes %20.
