What Changes in a PDF/A File
Converting to PDF/A makes these changes:
- Fonts are fully embedded — All fonts used in the document are baked in so the file renders correctly on any computer forever
- Colour spaces are standardised — Colours are specified with device-independent profiles
- JavaScript is removed — PDF/A does not allow executable code
- External links are removed — All resources must be self-contained within the file
- Metadata is standardised — Creation date, author, and title are stored in XMP format
When PDF/A Is Required in India
- Ministry of Corporate Affairs (MCA) — Company registration documents
- Income Tax Department — Assessment and appeal submissions via ITBA portal
- High Court and Supreme Court filings — E-filing portals specify PDF/A format
- SEBI filings — Regulatory submissions require archival-grade PDFs
- State government portals — Land records, mutation applications, and RTI responses often specify PDF/A
Frequently Asked Questions
What is PDF/A and why is it needed?
PDF/A is an ISO standard for archiving PDFs. It ensures the document is self-contained with all fonts, colours, and metadata embedded so it can be reproduced exactly the same decades later.
Does PDF/A look different from a regular PDF?
Visually identical. PDF/A simply has stricter rules about what can be embedded — no JavaScript, no external dependencies, fonts must be fully embedded.
Which PDF/A version should I use?
PDF/A-1b is the most widely accepted. PDF/A-2 and PDF/A-3 add support for newer features. Check the specific requirement of the government or legal body before converting.
