PDF/A-1b is an ISO 19005-1 profile of PDF for long-term archiving. It requires embedded fonts and self-contained content so the file renders the same way years later.

Will the file look different?

Content is preserved. Fonts are embedded and colors are converted to a device-independent space, which can slightly change color rendering.

Does conversion guarantee full validation?

The output targets PDF/A-1b compliance, but some source PDFs contain elements that cannot be converted cleanly. Validate the result if strict compliance is required.
