Quality & Fidelity

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.
