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.
Format referenceWhy convert PS to PDF?
- The result can be reviewed without changing the file that other people still use.
- PDF is more appropriate for the target application, device, or delivery channel than PS.
- 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.
Will quality change?
The result is a new document, not a byte-for-byte copy. Keep the source for reference and print checks. Check a sample before processing a large batch.

- Do not use a converted file as the legal or signed original when signatures or metadata must be preserved.
