Frequently Asked Questions
What is the difference between full URL and parameter encoding?
Full URL encoding keeps structure characters such as :/?&=, while parameter encoding is stricter for values such as search terms.
When should I use plus signs for spaces?
Use it when a form or query string expects spaces as + instead of %20.
What happens if decoding fails?
Broken percent-encoded input shows an error and clears the result so you do not copy an invalid string.
