While the converter is highly effective, users should be aware of specific technical behaviors during the process: QuarkXPress Document Converter (Windows only)

No independent body (like ISO or UL) certifies QuarkXPress converters. Verification is — based on reviews, trial tests, and developer claims.

QuarkXPress has a unique text engine. A verified converter preserves character spacing, hyphenation dictionaries, and font mapping. If your converter cannot handle .ufo or .otf font metrics, it isn't verified.
