Why Convert PDF to PDF/A?
PDF/A is an ISO‑standardized version of PDF designed for long‑term preservation and archiving. Unlike regular PDFs, PDF/A files are self‑contained: all fonts, colours, and metadata are embedded, and features that could break over time (like JavaScript or external references) are forbidden.
PDF/A Conformance Levels Explained
- PDF/A-1b – Basic compliance, ensures visual reproducibility. Based on PDF 1.4.
- PDF/A-2b – Adds support for JPEG2000, transparency, and layers. Based on PDF 1.7.
- PDF/A-3b – Same as PDF/A‑2b but allows attachment of any file type (e.g. XML, spreadsheets).
The tool above stamps your PDF with the correct XMP metadata and PDF/A identification. For full compliance, you may still need to ensure all fonts are embedded and that your content doesn’t use restricted features (such as encryption or interactive forms). Always validate with a dedicated checker.
When Should You Use PDF/A?
- Legal and government document archiving
- Academic theses and research papers
- Digital preservation of historical records
- ISO‑compliant document exchange in regulated industries
💡 Note: This free online tool adds the PDF/A conformance markers directly in your browser.
No file is ever uploaded to a server. For a fully validated PDF/A, consider combining it with a
PDF/A validator or a professional converter that also embeds fonts.
