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