The Free Online Way to Convert to PDF/A

PDF4me makes it simple to convert to PDF/A, the ISO standard built for long-term archiving, right in your browser. Drop in a regular PDF and get back a self-contained PDF/A file with its fonts embedded, so the document looks the same years from now. There is no software to install and no account needed to get started.
PDF/A is the format archives, libraries, and record keepers rely on because it keeps everything a file needs inside the document itself. Because everything runs online, you can convert to PDF/A from a laptop, a tablet, or your phone without changing a thing.

Built for Long-Term Archiving and Reliable Access

A standard PDF can rely on fonts or resources that live outside the file, which may go missing over time. PDF/A solves this by embedding fonts and keeping the document fully self-contained, so it opens and looks the same on any device in the future.
That makes PDF/A a trusted choice for archives, legal records, and compliance workflows where documents need to stay readable for years. Converting to PDF/A helps you meet long-term archiving requirements without special software.
