How EML Handles PST Data
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. PST Outlook Data preserves the full range. Email Message maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Email Message format supports it. Format-exclusive metadata fields that have no equivalent in Email Message are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality PST Outlook Data input produces an excellent Email Message output. Since the target format is lossless, output quality matches your input exactly.
Email format conversion from PST Outlook Data to Email Message preserves message content, headers, attachments, and folder structure. MIME encoding, embedded images, and HTML body content are maintained. This is critical for email migration between different mail clients and servers.
