Download the PDF/A
Keep the file with the guarantee it will open with the same appearance many years from now.
PDF/A is a version of PDF standardized by ISO (ISO 19005) and created specifically for long-term document preservation. Unlike a regular PDF, which can depend on fonts or resources external to the file, PDF/A embeds everything needed to display the document within the file itself, that's why it keeps the same appearance years later, regardless of the software used to open it.
This format is widely used by law firms, accounting firms, HR, healthcare, and government agencies to archive contracts, invoices, employee records, medical records, and official documents that need to remain readable and intact for a long time.
The conversion removes resources that could become invalid over time (like JavaScript, audio, and video) and embeds fonts and color profiles directly in the file. You can convert multiple PDFs at once, the result is a ZIP with one PDF/A per file submitted, with no daily limit and no account required.
PDF/A embeds all fonts and color information directly in the file itself and doesn't allow features like JavaScript, audio, video, or encryption. This guarantees the document looks the same on any device, today and decades from now, something a regular PDF doesn't guarantee.
PDF/A alone isn't a guarantee of legal validity, that depends on signatures, legislation, and retention policy for each case. But it's one of the most established formats for compliant document archiving.
We convert to PDF/A-2b, the most widely used level today, with support for transparency and better compatibility with modern PDFs.
Yes. Select as many PDF files as you need, up to 20 per batch. The result will be a ZIP with one PDF/A per file.
Usually yes, slightly, since fonts and color profiles get embedded directly in the file instead of depending on whatever system opens the PDF.
