When preparing documents for formal submission in China, in certain special cases, international teams may need to convert PDF files into the OFD format recognized in China. Although PDF is a widely used standard format globally, Chinese administrative systems and financial platforms require the OFD format because it is better suited for Asian typography and digital seals. Using traditional methods to individually convert dozens of contracts or reports can significantly reduce work efficiency in cross-border tasks. So, is there a way to batch convert many PDF files into OFD files?
This article introduces three simple tips to quickly convert an entire PDF document into a fully compatible OFD file while preserving the integrity of the entire document after conversion!
When should you convert PDF files to China's OFD format?
Compliance with Chinese government and business standards
The OFD format is recognized by Chinese authorities as the official electronic document standard. When companies conducting business in China need to submit invoices or official documents to Chinese government agencies, PDF files may not be accepted due to strict regulatory requirements. Converting them entirely to OFD format ensures compliance with local electronic document standards.
China's digital signature system
Foreign companies collaborating with Chinese enterprises or institutions may need OFD files for secure electronic signatures and verification. Unlike PDF, OFD primarily supports China's national encryption algorithms and digital authentication. Therefore, multinational corporations operating in China that convert PDF invoices and contracts to OFD format can avoid having their digital signatures rejected during identity verification.
Chinese software and archival systems
China is currently vigorously developing its local software ecosystem and information security independence. As China's dedicated electronic document standard, OFD has been deeply integrated into local office and archival systems. Foreign companies cooperating with Chinese entities may find that most Chinese office environments support OFD but have limited PDF compatibility. Hence, converting PDF to OFD ensures documents are displayed correctly and can be stored in China's digital archives without compatibility issues.
