Quoted-Printable Encoder & Decoder

Encode and decode quoted-printable, the MIME format used in email bodies and headers.

To encode quoted-printable, paste text containing non-ASCII characters and each byte outside the printable range becomes an equals sign followed by two hex digits. Lines are soft-wrapped at 76 characters, as required by the MIME specification for email.

Frequently asked questions

Where is quoted-printable still used?

Email. It encodes only the bytes that are unsafe, leaving ASCII readable, so a mostly-English message stays legible in the raw source — unlike Base64, which obscures everything. That readability is why email retained it.

What does =20 at the end of a line mean?

An encoded space. Trailing spaces must be encoded because mail servers strip them, and stripping one would change the message. =20 is a space that survives transport.
