Read a URL component without changing its meaning
A reproducible example
Hello%20world%21 decodes to Hello world! and a%26b decodes to a&b. This tool decodes a component using decodeURIComponent. It does not parse a whole query string or decide which characters are parameter separators.
A plus sign stays a plus sign
The input a+b remains a+b. Some HTML form query strings use + for a space, but that is a separate convention. Check how the sending system encoded the value before replacing plus signs.
Decode once and inspect the result
The input %252F becomes %2F after one pass; a second pass changes it to /. Do not repeatedly decode an untrusted URL and then open it automatically. Invalid escapes such as %ZZ or incomplete UTF-8 sequences produce an error; return to the source instead of guessing missing bytes.
