Why use PDF to PDF/A?
Archives, governments, and regulated industries often require PDF/A instead of everyday PDF. Converting to PDF/A-1b, PDF/A-2b, or PDF/A-3b baselines helps long-term readability and validator acceptance. PDFBaba exposes baseline choices so you can match submission requirements. No account is required, and uploads are short-lived. Validate the result with Validate PDF or your regulator’s checker—conversion success still depends on fonts, transparency, and embedded content in the source file.
Supported files & limits
One PDF; pick a PDF/A baseline (1b, 2b, or 3b). The default upload limit is 100MB per file; administrators can raise or lower this via server configuration. Common for archives and regulated submissions.
