Yeah, but when they do, it makes a difference.

Also, speaking from experience, most invoices do contain actual text.

Completely agree with this. This is what we've observed in production too. Embedding images makes the RAG a lot more robust to the "inner workings" of a document.

It makes sense. If you "print" to pdf it makes far more sense to keep the vector representation around. Rasterizing it would simultaneously bloat the file size and lower the quality level when transformed.
