FAQ
How do I convert a PDF to PDF/A?
Upload your PDF, click "Convert", and download your PDF/A file. If your PDF is password-protected, you'll be asked for the password first.
Is this PDF to PDF/A converter free?
Yes. ToolifyPDF is completely free with no sign-up and no watermark. You can convert up to 10 PDF files at once, up to 200MB each.
What is PDF/A?
PDF/A is an ISO-standardized version of PDF made for long-term archiving. A PDF/A file must contain everything it needs to display correctly, such as its fonts, and it can't rely on features like JavaScript, external content, or encryption. That way it can be opened the same way in the future.
Which PDF/A version does this tool create?
You choose. PDF/A-2b (recommended) is accepted almost everywhere and supports transparency. Pick PDF/A-1b if an archive or authority asks for it (transparent areas are flattened, since PDF/A-1 doesn't allow them), or PDF/A-3b if a system requires part 3. Level "b" (basic) guarantees that the document looks the same in the future.
What's the difference between PDF and PDF/A?
A regular PDF can depend on fonts installed on your computer, contain scripts, or be encrypted. PDF/A forbids those features and requires everything to be embedded in the file, so the document always looks the same, now and in decades.
Will my PDF look the same after converting?
Your text, images, and layout are kept, and the fonts are embedded in the file. Features that PDF/A doesn't allow, such as JavaScript or embedded media, are removed.
Can I convert a password-protected PDF to PDF/A?
Yes. You'll be asked for the password when you upload the file. PDF/A doesn't allow encryption, so the PDF/A file is saved without a password.
Can I convert multiple PDF files to PDF/A at once?
Yes. You can convert up to 10 PDF files at once. A single file is downloaded as a PDF, and several files are downloaded together in a ZIP file.
How can I check that a file is PDF/A?
You can check any PDF/A file with a free validator such as veraPDF. It tests the file against the PDF/A rules and lists anything that doesn't comply. This is a good idea if an archive or authority requires strict PDF/A compliance.
Do I need to install software to convert PDF to PDF/A?
No. ToolifyPDF converts PDF to PDF/A online in your browser, so there's nothing to download or install. It works on Windows, Mac, Linux, iPhone, and Android.
Advanced Features
Our online PDF to PDF/A converter offers several useful features:

💡 Pro Tip
Always keep your original PDF next to the PDF/A version. Converting removes features that PDF/A doesn't allow, such as form scripts or encryption, so the original is still useful if you need to edit or reuse it.
