Decode Quoted-Printable text

Convert MIME Quoted-Printable (RFC 2045) back into readable text. Each =XX escape (case-insensitive) expands to its byte, soft line breaks (a = before a line ending) are dropped, CRLF and LF are both accepted, and the accumulated bytes are decoded as UTF-8. A malformed escape that is not two hex digits or a soft break is reported as an error.

When to use this tool

Use Quoted-Printable when you need to produce or inspect the transfer encoding email clients use for mostly-ASCII 8-bit text, such as hand-writing MIME parts, debugging email or webhook payloads, or reading raw .eml files full of =XX escapes and soft line breaks.

Privacy and limitations

This conversion runs locally in your browser. Quoted-Printable is an encoding format, not encryption, so anyone can decode the result. It is a single text-to-text converter: RFC 2047 encoded-word headers (=?UTF-8?Q?…?=), full MIME or multipart parsing, and attachments are out of scope.
