This converter allows you to upload your PDF and convert it into a PDF/A format suitable for archiving and long-term preservation of electronic documents. PDF/A files created with our online converter are ISO-compliant and pass VeraPDF validation. For a detailed insight into PDF/A standards, conformance levels for PDF files, and their features, visit the Wikipedia page.

NOTE: While higher conformance level (a or u) can certainly improve the value of your documents, they can also be quite time consuming. By selecting the B level conformance, PDF/A-2b for example, your documents will conform with guidelines for reliable viewing, without imposing extra requirements.
