PDFMaxConvert PDF to PDF/A Online
PDF/A is the ISO-standardized version of PDF built for long-term archiving. Unlike a regular PDF, a PDF/A file is self-contained: fonts, colors, and images are embedded, and features that can break over time, like external links, encryption, or scripts, are removed. That keeps your document readable years from now, no matter what software people use. With PDFMax you can convert any PDF to PDF/A right in your browser. It is free, needs no signup and no install, and works the same on phone, tablet, or computer. Just upload your file and download the archival version.
