What is PDF/A?

PDF/A is a standardized version of the PDF format designed for long-term digital preservation of electronic documents. It ensures that files can be reproduced exactly the same way in the future.

What is PDF/A-1b used for?

PDF/A-1b ensures the visual appearance of the document is preserved. It's the most basic conformance level and meets the minimum requirements for archiving.

Can I search text in PDF/A-1b?

Yes, but only if the document includes a text layer. It does not guarantee Unicode text support.

How is PDF/A-2b different from PDF/A-1b?

PDF/A-2b supports more modern features like JPEG2000 compression, transparency, layers, and embedding OpenType fonts, while still preserving visual appearance.

What does the 'u' mean in PDF/A-2u?

The 'u' stands for Unicode. PDF/A-2u ensures that all text can be reliably searched and copied, improving accessibility and text extraction.

What makes PDF/A-3b unique?

PDF/A-3b allows you to embed other file types (like XML, CSV, DOCX) within the PDF, while maintaining visual fidelity.

Why choose PDF/A-3u?

PDF/A-3u combines Unicode support with the ability to embed other file formats. It’s ideal when you need both searchable text and original source files stored together.
