About this tool

Decodes text in Quoted-Printable format, the encoding often seen in email bodies. Each =XX sequence, where XX is two hex digits, becomes the byte it stands for, and the bytes are read as UTF-8, so =C3=A9 turns into é. A soft line break, an equals sign at the end of a line, is removed so wrapped lines join back together. If the bytes are not valid UTF-8, for example Latin-1 content like =E9 alone, the tool falls back to turning each byte into one character, so =E9 becomes é. That fallback is right for Latin-1 but wrong for other character sets. The tool does not read MIME headers or other parts of the email. It runs in your browser.

How to use it

  1. Paste the Quoted-Printable text.
  2. Read the decoded text in the output.
  3. If letters look wrong, check which character set the email declares.

Example

Input
caf=C3=A9 au =
lait
Result
café au lait

Common problems

Accented letters look wrong
The fallback treats every byte as a Latin-1 character. If the email uses another character set, such as Windows-1253 or Shift_JIS, the result will show the wrong letters.
Words are still split with = at line ends
Only an = directly at the end of a line is treated as a soft break. Trailing spaces after the = prevent that.
Headers and other MIME parts are included
Paste only the encoded body. The tool does not parse the email structure.
