FAQ
What is PDF/A?
PDF/A is an ISO-standardized version of PDF designed for long-term archiving. It restricts certain features (like encryption and external content) to ensure documents remain viewable in the future.
Which level should I choose?
PDF/A-1b is the baseline and most widely accepted. PDF/A-2b adds newer features (layers, JPEG2000), while PDF/A-3b allows embedding files inside the PDF (e.g., original source files).
Why enable sRGB?
Embedding sRGB ensures color-managed output and better consistency across viewers and printers.
What does OCR do?
OCR turns scanned images into searchable text before conversion, improving accessibility and retrieval.
