How it works

Email parts often use Content-Transfer-Encoding: quoted-printable or base64.

  1. Step 1

    Paste one part

    Use the encoded body, not the whole mailbox. Soft line breaks (= at end of line) are removed.

  2. Step 2

    Pick the encoding

    Quoted-printable for text with =C3=A9 style bytes. Base64 for binary or HTML parts.

  3. Step 3

    Copy or download

    The decoded text stays in this tab.

MIME decoder FAQ

Is this the same as an EML viewer?

No. This decodes one blob. The EML viewer splits a full message into headers, text, HTML and attachments.

Why do I see odd characters?

Pick UTF-8 unless the part declared another charset. Quoted-printable is decoded to bytes then read as UTF-8.
