About This Tool
Standard PDFs can change over time based on external fonts or software updates. PDF/A (Portable Document Format Archive) is an ISO-standardized version of PDF that guarantees a document can be opened and read exactly as it is today, 50 years from now.
Our converter supports multiple levels of conformance:
- PDF/A-1b: The most common level for basic visual reproducibility.
- PDF/A-2b: A more modern standard that supports transparency and JPEG 2000 compression.
- PDF/A-3b: Allows embedding of any other file format (like CSV or XML) within the archival PDF.
The tool automatically embeds all fonts, sets color profiles, and removes non-archival elements like JavaScript or encryption.

Frequently Asked Questions
What is the "b" in 2b stand for?
The "b" stands for "basic" conformance, which ensures that the visual appearance of the document is preserved.
Will my file size change?
Yes, often the file size increases because the tool must embed the full font data into the document so it doesn't rely on your computer's fonts.
Does it remove passwords?
Yes. PDF/A standards do not allow encryption or passwords, as they might prevent the file from being opened in the future.
