About PDF to PDF/A
For records that must survive for years, an ordinary PDF isn't enough. Archives, courts, and compliance rules often require PDF/A, a format built to display the same way decades from now by embedding everything the document needs. This tool converts your PDF into that archival standard.
Upload your file and the tool rewrites it to meet the PDF/A specification, embedding fonts and resources so the document stays self-contained and stable over time. It works in your browser, so your files stay private. It's free, needs no account, and adds no watermark. It's the right step before storing important documents for the long haul.

FAQ
Why is PDF/A better for archiving?
PDF/A embeds fonts and other resources and avoids features that could break over time, so the document reliably looks the same far into the future.
Will my document look different after conversion?
The aim is to preserve appearance. PDF/A keeps the visible content the same while making the file self-contained.
Can I edit a PDF/A file later?
You can still work with it, but PDF/A is meant for stable, final archival copies. Keep an editable original if you expect to make changes.
Can I use PDF to PDF/A on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
