Why Convert OFD to PDF?
OFD (GB/T 33190) is China's national standard for fixed-layout documents, mandated for official invoices (fapiao), tax filings, and government/legal documents — but outside systems built to handle it, most PDF readers, browsers, and international software have no idea what to do with an .ofd file.
PDF is the format everyone can open, everywhere, which is why converting is the standard next step the moment an OFD document needs to be shared, archived, or reviewed by someone outside a China-specific software ecosystem.
Our conversion preserves the fixed-layout structure OFD is built around — exact positioning of text, tables, and seals — so the PDF looks identical to the original OFD, not a re-flowed approximation.

Frequently Asked Questions
What is an OFD file, exactly?
OFD is a Chinese national standard (GB/T 33190) for fixed-layout electronic documents, used extensively for official invoices (fapiao), tax documents, and government filings in China — functionally similar to PDF but specific to Chinese regulatory systems.
Will official seals and signatures be preserved?
Yes — the visual appearance of seals, stamps, and signatures embedded in the OFD is preserved in the converted PDF, since fixed-layout formats are specifically designed to keep exact visual presentation intact.
Why did my OFD file fail to convert?
Most failures come from very small or corrupted upload files (sometimes 0 bytes) rather than the conversion itself — genuine OFD documents from standard invoicing/tax systems convert reliably.
Do I need special Chinese government software to open OFD files first?
No — upload the .ofd file directly to our converter. You don't need OFD-specific viewer software from Chinese tax or government systems.
Is the converted PDF suitable for official use, like tax filing records?
The conversion preserves the visual layout exactly, making it suitable for archival and viewing purposes. For official regulatory submissions, check your specific jurisdiction's requirements for accepted formats.
How do I open an OFD file without a special reader?
Opening an .ofd directly normally requires a China-specific OFD reader or viewer, which most people outside those systems don't have installed. The simplest way to open one anywhere is to convert it to PDF here and view it in any standard PDF reader or browser.
