About Portable Document Format
Predictable layout on every device, strong print fidelity, universal viewers, and support for signatures and forms. Editing is harder than editing a word processor document; reflow, accessibility, and text extraction depend on how the PDF was produced.

- PDF is more appropriate for the target application, device, or delivery channel than CBZ.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
