Supports PDF files
PDF/A is an ISO-standardized version of the PDF format designed for long-term archiving and digital preservation. It ensures that documents remain reliably reproducible over time without requiring external resources.
What this tool does: This tool performs a best-effort conversion by optimizing your PDF's internal document structure, setting required metadata (title, creation date, modification date), and re-serializing using a PDF/A-compatible object format without object streams.
Limitations: Full PDF/A compliance requires embedding all fonts, color profiles, and removing encrypted content. This tool addresses structural metadata and serialization. For strict compliance certification in regulated industries, a dedicated archiving tool or professional PDF/A validator may be required.
Privacy: All processing happens locally in your browser using pdf-lib. Your files are never uploaded to any server.
