OCR wont runt for some files?

Hi,

For some pdf files the OCR wont runt. I can’t figure out why as scans are good. Any suggestion? Any way to force the OCR to run?

Thanks!

Below text was wrong, please ignore:
a question regarding OCR for PDF files.
In many cases the OCR works great in DevonThink, and I noticed the kind is filed as “PDF+Text”.

But for some files OCR wont runt, mainly large PDFs for 15MB and above. Is there a limit on the file size from where the OCR wont run?

The filesize shouldn’t be an issue, it’s not limited. But if no text could be recognized then the type remains PDF even after OCR.
