FAQ
URL Encoder questions.
Should I use URI or component mode?
Use component mode for query parameter values. Use URI mode when encoding an entire URL while preserving URL separators.
Can this decode percent-encoded URLs?
Yes. Paste encoded text and use the decode mode to convert it back into readable characters.
