Convert MIME-Encoded Email Text Back to Readable Format - Email Decoding Tool

What is the Quoted-Printable Decoder Tool?

The Quoted-Printable Decoder is a free online utility that converts Quoted-Printable encoded text back into its original, human-readable format. This tool reverses the MIME content transfer encoding, transforming encoded sequences like =C3=A9 back to é, or =D1=81=D1=82=D1=80=D0=BE=D0=BA=D0=B0 back to строка (Russian text), making email messages and encoded content readable again.web-tool+1​

Whether you're troubleshooting email delivery issues, extracting readable text from corrupted emails, debugging MIME message parsing, or analyzing email data, the CyberTools Quoted-Printable Decoder provides instant, accurate decoding that restores encoded email content to its original form.toolsina+2​

What is Quoted-Printable Decoding?

Quoted-Printable decoding is the process of converting MIME-encoded text back into its original 8-bit string format. Quoted-Printable is a text encoding system that uses printable ASCII characters, applied for encoding/decoding data in email messages. The decoding process reverses the encoding, transforming sequences like =3D back to =, =0A to line feeds, and multi-byte sequences like =C3=A9 back to accented characters.onlinephp+2​

How Quoted-Printable Decoding Worksonlinephp​

The decoding process:

Step 1: Identify Encoded Sequences

  • Find =XX patterns where XX are hexadecimal digitsweb-tool​
  • Recognize soft line breaks (= at end of line)
  • Detect character encoding sequences

Step 2: Convert Hex to Bytesonlinephp​

  • Each =XX represents a single byteweb-tool​
  • Convert hexadecimal to decimal value
  • Map to character based on encoding (UTF-8, ISO-8859-1, etc.)

Step 3: Handle Soft Line Breaks

  • Remove = at line endings (soft breaks)
  • Join continued lines
  • Preserve actual line breaks (CRLF)

Step 4: Reconstruct Original Text

  • Combine decoded bytes
  • Apply character encoding (UTF-8, etc.)
  • Return human-readable stringonlinephp+1​

Example decoding:web-tool​


text
Encoded: =D1=81=D1=82=D1=80=D0=BE=D0=BA=D0=B0
Process: Each =XX is a UTF-8 byte
Result: строка (Russian: "string")

Common Encoding Patterns

Basic encodings:

  • =3D → = (equals sign)
  • =20 → space (at line end)
  • =0A → line feed
  • =0D → carriage return

UTF-8 multi-byte sequences:

  • =C3=A9 → é (e-acute)
  • =C3=B1 → ñ (n-tilde)
  • =E2=82=AC → € (Euro sign)

Soft line breaks:


text
This is a long line that=
 continues here
→ "This is a long line that continues here"

Can I decode email attachments?

Attachments use different encoding:

Email attachments typically use:

  • Base64 encoding - Not Quoted-Printable
  • Binary content transfer encoding
  • MIME multipart format

Use Base64 decoder for attachment data.

What if decoded text is still garbled?webatic​
