FAQ

URL FAQ

What is a URL?
A URL (Uniform Resource Locator) is a string that identifies the location of a web resource.
What is a query string?
It’s the list of key=value parameters after ?, with multiple parameters separated by &.
Can query parameter keys repeat?
Yes. The same key can appear multiple times (e.g. tag=a&tag=b), and servers may interpret this differently.
When do I need percent-encoding?
Use it to safely represent spaces, non-ASCII characters, and reserved characters inside a URL.
How are relative URLs parsed?
Relative URLs are resolved against a Base URL to form an absolute URL.
Which standard does this follow?
This tool uses the browser's standard URL parser (URL/URLSearchParams).
Is my input uploaded anywhere?
No. This tool runs entirely in your browser and does not send your input externally.
