Compression Settings (Reduce EML Size)

[ ? ]
Remove the Text Body if HTML Body is Present
Removes plain-text part when HTML body exists, reducing file size without affecting readability.
Remove Headers that are Not Required
Removes network headers like Received, DKIM-Signature, X-Headers to reduce file size.

Remove Text Body if HTML Body is Present

— Smart content optimization
How it works: If you select this option, the tool will analyze the internal structure of EML files to identify both plain text and HTML body parts.

Commonly, EML files contain two parts:

  • The plain text — Basic text content without formatting
  • The HTML body — Contains the complete message with formatting
Why it's safe: Since the HTML body already contains the complete message, removing the plain text part will not affect the readability of the EML file. That's how the tool will reduce the EML file size efficiently.
Result: Smaller EML files with all content and formatting preserved. Perfect for archiving and storage optimization.
Preserves Full Readability

📝 Note: The RecoveryTools EML Converter offers users a check-box option to reduce the size of EML files using smart compression settings. If you enable these options, the software will automatically apply the selected compression method—such as removing unnecessary network headers or eliminating the plain-text part when an HTML body exists.

Remove Headers that are Not Required

— Network header optimization
How it works: If you select this option, the tool will remove the network header part of the EML files. These headers are not user-side; they are created by email servers automatically to manage delivery, authentication, and routing.
Why it's safe: Removing these headers will not affect the readability of compressed EML files. The actual email content, sender, recipient, subject, and date remain intact.

Headers removed by the tool:

Received Return-Path Authentication-Results DKIM-Signature SPF Results X-Headers
Result: Significantly reduced file size while maintaining all essential email information for everyday use.
