What is the difference between "value" and "address" mode?

Value mode encodes every special character, which is right for a query parameter. Address mode keeps the characters that give a link its structure, such as : / ? # & and =, and is right for a whole link.

Why is a space shown as %20 or as +?

%20 is the standard way to write a space in a web address. Some forms use + instead. When decoding, you can choose to treat + as a space.

Does URL encoding make a link safe or secret?

No. It only makes the text valid inside a web address. Anyone can decode it.

URL Encode & Decode

Encode special characters in a link or a value so they are safe to use in a web address, or decode them again.

Your files never leave your device

Choose Encode or Decode, pick whether you have a whole address or a single value, then type or paste your text.

About this tool

URL Encode & Decode changes special characters such as spaces, accents and symbols into the %XX form used in web addresses, and back again. Choose between encoding a whole address or a single value. It runs in your browser, so nothing is uploaded, and it is free with no sign-up.

Good to know: Encoding is not encryption. Use "value" mode for query parameters and "address" mode for a whole link.

Your files are processed entirely in your browser — nothing is ever uploaded to any server. Verify it yourself
