Standardizing fonts and metadata for PDF/A... please wait.

What is PDF/A and Why Do You Need It?

At Viral Base Tool, we provide specialized tools for document integrity. PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents.

Unlike standard PDFs, PDF/A requires all information necessary for displaying the document (like fonts and color profiles) to be embedded directly into the file. This ensures that your document will look exactly the same 20, 50, or even 100 years from now, regardless of the software used.

Simple Conversion Steps:

  1. Select the standard PDF document you wish to archive.
  2. Our tool will automatically embed fonts and remove non-compliant elements (like JS or audio).
  3. Download your ISO-compliant PDF/A file, ready for your digital vault.
