FAQ
When do I need URL encoding?
When URLs contain spaces, Chinese characters or reserved symbols — they must be percent-encoded for transmission.
What is the difference between encodeURI and encodeURIComponent?
The tool offers both modes: full-URL encoding preserves URL structure, component encoding escapes everything.
Is + the same as %20?
Both mean space, but in different conventions (+ in form data, %20 in paths). The tool decodes both.
