About OFD
An OFD is a ZIP of pages written in XML, each page's text, drawings and pictures placed exactly, like a PDF's, with the fonts it carries, its templates, attachments and the seals that sign it. China made it its national standard, GB/T 33190, in 2016, as a page format of its own to stand beside PDF.
China's tax offices issue e-invoices as OFD files, with the invoice's data attached as XML and the tax office's red seal stamped on it, and government offices, banks and archives keep their papers in it. Windows, Macs and phones don't open it, so it needs a reader from a Chinese vendor, and fonts like 宋体 that a file only names often show as gaps or boxes outside China.
Filepeek draws every page in your browser into a PDF, with the fonts the file carries, or Noto's Chinese fonts where it only names them, and its pictures, templates and seals, then shows it with zoom, page thumbnails and search. Show details lists what it says of itself, its attachments and who signed it, and Export saves it as a PDF, or its pages as PNG or JPEG.

Questions
Why did my invoice come as an OFD?
China's e-invoices are issued as OFD files, often with a PDF beside them. The OFD is the one the tax office signs, with the invoice's data attached as XML.
Is the seal on my OFD checked?
No. Filepeek shows each seal as it's stamped and names the signature, its method and when it was made, but doesn't check it. The tax office's own service checks an invoice.
Can I turn an OFD into a PDF?
Yes. Choose Export, then Save as PDF. Each page is drawn into the PDF in your browser, its text kept as text, so it can still be searched and copied.
