What Is PDF/A and When Do You Need It?
The archival PDF standard explained.
PDF/A is a version of PDF designed for long-term archiving — everything needed to display the file is embedded.
ChangeMyPDF runs entirely in your browser — your files never leave your device, there's nothing to install, and you can start without an account. Here's exactly how to do it.
Step-by-step
- PDF/A embeds fonts and disallows external dependencies.
- It ensures the file opens the same decades later.
- Many institutions require it for records.
- Convert standard PDFs when archiving is required.
Tips for the best result
- Use PDF/A for legal and government records.
- Keep a normal PDF for everyday editing.
Is it safe and free?
Yes. Most ChangeMyPDF tools process files locally in your browser, so documents are never uploaded to a server. Free accounts can run a few operations per hour; a Week Pass or Premium plan removes the limit and ads if you need to do more.
