What is PDF/A?
PDF/A is a specialized, ISO-standardized version of the Portable Document Format (PDF) designed for the long-term archiving and preservation of electronic documents.
Built for the Future
The primary goal of PDF/A is to ensure that documents can be reliably reproduced and viewed exactly the same way in the distant future, regardless of the software or hardware used. To achieve this, PDF/A has strict rules:
- All Fonts are Embedded: Every font used in the document is included within the file itself.
- No External Dependencies: The file cannot link to external content like videos, audio, or external hyperlinks.
- Standardized Metadata: Document metadata (like author, title) is stored in a standardized format.
- Device-Independent Color: Colors are defined in a way that ensures they look the same on any device.

PDF/A-1
Based on PDF 1.4. Level 'a' (Accessible) requires document structure tagging, while 'b' (Basic) only ensures reliable visual reproduction.
PDF/A-2
Based on PDF 1.7. Adds support for JPEG2000 compression, transparency, and layers. Level 'u' (Unicode) requires all text to be in Unicode.
PDF/A-3
Similar to PDF/A-2, but allows embedding of other file formats (like XML or CSV) into the PDF/A document.

Frequently Asked Questions

Is it safe to upload my documents here?
Yes, it is 100% safe. Your privacy is our top priority. The entire conversion process happens locally in your browser. Your files are never uploaded to our servers, ensuring your data remains completely private.
Which PDF/A level should I choose?
For most archiving purposes, PDF/A-2b is a great choice as it ensures visual preservability and supports modern PDF features. If your document needs to be accessible for users with disabilities, choose a Level 'a' conformance (e.g., PDF/A-2a). Check with your institution or organization for specific requirements.
Will converting to PDF/A change how my document looks?
No, the primary goal of PDF/A is to preserve the original visual appearance of the document. The content, layout, and colors should look exactly the same as the original file. The main changes are internal to the file's structure to ensure long-term stability.
What happens to my file after I'm done?
Since your file is never uploaded, it remains on your computer. The converted PDF/A is generated in your browser, and you download a new copy. We never see, access, or store your original or converted files.
