How the Quoted-Printable Encoder/Decoder Works

What the Tool Does

The quoted-printable encoder/decoder converts text to and from quoted-printable format, an email encoding standard defined in RFC 2045. This encoding method is used in email headers and bodies to safely transmit text that may contain special characters or non-ASCII characters. When you need to encode email content, process email data, or work with quoted-printable encoded text, this tool provides reliable encoding and decoding capabilities. The quoted-printable format represents non-printable or special characters as =XX where XX is the hexadecimal value of the character, and uses soft line breaks (=) to keep lines under 76 characters.

Common Developer Use Cases

Developers use quoted-printable encoding when working with email systems, processing email headers, or handling email content that contains special characters. The quoted-printable encode functionality is essential when building email clients, processing email attachments, or working with email APIs that require quoted-printable format. Many developers need quoted-printable decode when parsing incoming emails, extracting email content, or debugging email-related issues. The encoding is particularly useful for email bodies that contain non-ASCII characters, special symbols, or formatting that needs to be preserved during transmission. Quoted-printable encoding ensures email content is transmitted safely across different email systems and protocols.
