Hello @Dominic Dubreuil , Thanks for using Microsoft Q&A Platform.
Unfortunately, pdf
document type is not yet supported with Synchronous single file formats. However, using Asynchronous batch translation it is supported.
Please review this documentation: https://learn.microsoft.com/en-us/azure/ai-services/translator/document-translation/overview
I hope this helps.
Regards,
Vasavi
