What are the limits of PDF/A Preflight Checker?
This is a limited PDF/A-2b preflight, not a complete ISO conformance validator or certification. It checks selected structural indicators and cannot prove all content-stream, color-space or profile rules. The report explicitly retains a manual/full-validation requirement. Encrypted PDFs must be opened in authorized software first. Processing stays in this browser. No input files, fonts or reports are uploaded. Engines download from this website on first use; no external document links are fetched. PDFs up to 20 MB / 200 pages unless a stricter limit is stated; output up to 80 MB. Close or clear the editor to discard the local draft.
