Questions about this workflow
Can this process PDFs or audio too?
The selected action is OCR for images. Use it when the confirmed source is an image, not as a general file or audio processor.
Does the workflow modify the uploaded Canvas file?
No. It extracts text from the confirmed image source; it does not replace or edit the original upload.
