Quoted-Printable Encoder

Quoted-Printable Encoder converts text to and from Quoted-Printable encoding as defined in RFC 2045 and the MIME standard. In Quoted-Printable encoding, every byte that is not a printable ASCII character is represented as an equals sign followed by two uppercase hexadecimal digits, for example the byte 0xE9 becomes =E9. This encoding keeps mostly ASCII text directly readable while making non-ASCII characters safe for transport through email systems that only guarantee 7-bit ASCII transmission. Lines are wrapped at 76 characters using soft line breaks (=CRLF) as required by RFC 2045.

How to Use

Paste your text into the input field and click Encode to apply Quoted-Printable encoding. All bytes above 0x7E and control characters below 0x20 (except tab and space) are encoded as =XX sequences, and lines exceeding 76 characters are split with soft line breaks. To decode, paste Quoted-Printable encoded text and click Decode to recover the original content. The tool correctly handles both CRLF and LF line endings and strips soft line breaks during decoding.

Common Use Cases

• •Encoding email message body text containing non-ASCII characters such as accented letters for safe SMTP transport
• •Decoding Quoted-Printable encoded sections found in raw .eml files or email server logs for content inspection
• •Debugging email rendering issues where special characters appear as garbled text due to encoding mismatches
• •Preparing MIME multipart message body parts with correct Quoted-Printable encoding for email template testing
• •Verifying that an email sending library applies Quoted-Printable encoding correctly before deploying transactional email templates
