What Is Quoted-Printable Encode?

Quoted-Printable (QP) encoding is a MIME content transfer encoding defined in RFC 2045 for email. It keeps ASCII text readable while encoding non-ASCII characters as =HH (hex). Lines are limited to 76 characters with soft line breaks (=). Designed for text that is mostly ASCII with occasional special characters. The = character itself becomes =3D. This tool performs RFC 2045 compliant encoding with proper line wrapping. All processing is client-side.

Why Use Our Quoted-Printable Encode?

  • RFC 2045 compliant for email compatibility
  • Keeps ASCII text readable in the encoded output
  • Proper 76-character line wrapping with soft breaks
  • 100% client-side — data never leaves your browser

Common Use Cases

Email Encoding

Encode email body content for MIME transport.

MIME Messages

Create quoted-printable encoded messages.

Legacy Systems

Encode text for systems requiring 7-bit ASCII transport.

Testing

Generate QP-encoded test data for email system testing.

Technical Guide

Quoted-Printable represents each non-printable or non-ASCII byte as =HH where HH is its hex value. Printable ASCII (33-126 except =) and spaces/tabs (when not at line end) pass through unchanged. Lines limited to 76 characters via soft breaks. The = character is encoded as =3D. Tab and space at end of line are encoded.

Tips & Best Practices

  • 1
    QP encoding is ideal for mostly ASCII text with some special characters
  • 2
    Soft line breaks (trailing =) indicate wrapped lines
  • 3
    The = character itself is always encoded as =3D
  • 4
    For binary data, Base64 is more efficient
