About this tool
Component encoding escapes the reserved delimiters (& = ? / #) because you are building a value that goes inside a URL. Full-URI encoding leaves them alone because they are doing their job.
Questions
- Component or whole-URL mode?
- Component, almost always. Use it when encoding one piece — a search term, a filename — that is about to be inserted into a URL. Whole-URL mode preserves / ? & = # and is only right when you are handing it a complete URL.
- Should spaces be %20 or +?
- %20 works everywhere. The plus sign means a space only in query strings, inherited from HTML form encoding — in a path it is a literal plus.
- I see %2520 in my URL.
- Something encoded an already-encoded value. %25 is an encoded percent sign, so %20 became %2520. Decode repeatedly until it stops changing to recover the original.
