PPT to HTML Quality Analysis

The conversion maps between these approaches intelligently. PowerPoint 97-2003's known limitation — binary format limited to 256MB, macro vulnerability — is resolved when converting to HTML Document, which offers universal web standard rendered by every browser on every device. The PowerPoint 97-2003 source uses lossless encoding. The HTML Document output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient.
