OST to YAML Quality Analysis
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. OST Offline Outlook preserves the full range. YAML Data maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the YAML Data format supports it. Format-exclusive metadata fields that have no equivalent in YAML Data are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality OST Offline Outlook input produces an excellent YAML Data output. Since the target format is lossless, output quality matches your input exactly.
