Frequently Asked Questions

Why do URLs have %20 in them?

URLs cannot contain spaces. A space is encoded as %20 or a plus sign (+) when transmitted. Our decoder turns these back into spaces.

What does 'Malformed URI sequence' mean?

This error occurs when the input contains a percent sign (%) that isn't followed by two valid hexadecimal digits, making it impossible to decode properly.

How are query parameters extracted?

If the decoded result is a valid web address, we parse the part after the question mark (?) and break it down into clean key-value pairs for easy reading.

Does this decode '+' into spaces?

Yes, in Component mode, we automatically convert '+' signs into spaces before decoding, as this is the standard for URL query strings.

Is batch decoding supported?

Yes, toggle Batch Mode and paste a list of encoded strings separated by line breaks. They will all be decoded simultaneously.
