What is URL Encoding (Percent-Encoding)?
URLs (web addresses) can only be sent over the internet using the standard ASCII character set. If your URL contains characters outside of this strict set (like spaces, emojis, or international characters like “é”), they must be translated.
URL encoding replaces these unsafe characters with a “%” followed by two hexadecimal digits. For example:
- A space ( ) becomes
%20 - An exclamation point (!) becomes
%21 - An ampersand (&) becomes
%26
If you fail to encode a URL properly before putting it in a database or email, the link will likely break, leading to frustrating 404 errors for your users.
Frequently Asked Questions (FAQ)
Why did the Decoder give me a “Malformed URI” error?
This happens if you attempt to decode a string that was not properly encoded in the first place, or if it contains a solitary “%” symbol that is not followed by a valid two-digit hex code. Ensure the string you pasted is an exact copy of a valid encoded URL.
Does this tool handle “+” symbols as spaces?
Yes! In legacy URL query strings, spaces were often encoded as `+` instead of `%20`. Our decoder intelligently detects `+` symbols and translates them back into standard spaces for perfect readability.
