Frequently Asked Questions
What is PDF/A?
PDF/A is an ISO-standardized version of PDF designed specifically for long-term archiving, ensuring a document looks the same no matter what software or hardware opens it in the future.
Which PDF/A version does this tool produce?
Files are converted to PDF/A-2B, one of the most widely accepted PDF/A conformance levels.
Will the colors in my document change?
Colors are converted to the RGB color space as part of meeting the PDF/A-2B requirements. Most documents look the same, though very color-precise print files may see a slight shift.
Can I convert multiple PDFs to PDF/A at once?
Yes. Upload several files and each one is converted and returned together in a single zip download.
What happens if a file can't be converted?
If the file cannot be verified as valid PDF/A after conversion, it's excluded from your download rather than returned in a broken state.
Is it safe to upload confidential documents?
Yes. All uploads happen over an encrypted connection, and both the source file and the converted PDF/A file are automatically deleted from our servers after processing.
Is converting to PDF/A really free?
Yes. There is no cost, no subscription, and no account required.
Can I convert PDF/A back to a regular PDF?
A PDF/A file is still a standard PDF and opens normally in any PDF reader. There's no separate conversion needed to use it like any other PDF.
