Free PDF to PDF/A Converter Online – Long-Term Archiving Made Easy
PDF is the most common format for sharing documents because it preserves fonts, layouts, and graphics across devices. However, standard PDF files are not always suitable for archiving and long-term preservation. Over time, fonts may not display correctly, links may break, and embedded elements may not remain consistent.
That’s where PDF/A comes in. PDF/A is an ISO-standardized version of PDF designed specifically for long-term archiving. By converting your PDF into PDF/A format, you ensure that your document can be opened, read, and preserved in the same way even decades from now.
Our Free PDF to PDF/A Converter makes this process easy, secure, and fast — directly from your browser.
What is PDF/A?
PDF/A (Portable Document Format – Archival) is a special type of PDF standardized by the International Organization for Standardization (ISO 19005). It is designed for archiving digital documents so they remain accessible in the future, regardless of the software used.
Unlike normal PDFs, a PDF/A file must:
- Embed all fonts used in the document
- Avoid features like encryption or JavaScript (which may not be supported in the future)
- Contain metadata for long-term identification
- Preserve colors and layout exactly as in the original
This ensures maximum reliability and compatibility for archiving.
Why Convert PDF to PDF/A?
- Long-Term Preservation – Documents remain readable in the same format decades from now.

- Reliable Metadata – PDF/A stores important information like author, title, and keywords for easy searching.
