PDF/A files created with our free online tool are ISO-compliant and pass VeraPDF validation. VeraPDF is an open source PDF/A validator supported by the PDF industry and led by the Open Preservation Foundation.
Getting a typical PDF file to conform to PDF/A-1 usually requires the most changes. With PDF/A-2, in contrast, you will need to make fewer changes and you will get smaller files. PDF/A-3 is essentially the same as PDF/A-2, but it allows for the embedding of non-PDF/A files.
As for conformance level, Level A is often not practical because of missing Unicode orsemantic information in the source. Level B it is the easiest conformance level to target while ensuring reliable rendering. Level U ensures that all text has Unicode equivalents. Learn More
