You’re aware that PDFs are containers that can hold various formats, which can be interlaced in different ways, such as on top, throughout, or in unexpected and unspecified ways that aren’t “parsable,” right?

Could be. But their pricing for the conversion is free, which leads me to believe LLMs are not involved.
