Multipart MIME bundles several parts (text, attachments, form fields) separated by a boundary string. Each part has its own headers and body. Parsing requires splitting on the boundary and decoding each part's Content-Transfer-Encoding.
- 2 MIME-Dekodierer →
Paste the full multipart message. The tool splits on the boundary, extracts each part's headers and body, and applies the transfer encoding (base64, quoted-printable, 7bit).
- 3 MIME-Typen-Referenz →
Look up the Content-Type of each extracted part to understand how to render or save it (e.g. image/jpeg → save as binary, text/plain → display).
- 4 Base64-Dekodierer →
If a part's body is still Base64 after MIME decode (nested encoding), decode it here to recover the original bytes.
Häufige Fragen
- Where do I find the boundary string?
- It is declared in the top-level Content-Type header as boundary="...". The actual separators in the body are prefixed with two dashes (--boundary), and the final separator is followed by two dashes.
- Why are some parts empty?
- Multipart/form-data often includes empty parts for unset form fields, or a leading/trailing empty segment from the boundary split. Filter parts with empty bodies after parsing.
