What happens if the hybrid OCR backend is offline?

The tool automatically falls back to standard text extraction and includes a warning in the metadata to inform you of the fallback.

Can I process only specific pages of a long PDF?

Yes, you can define specific pages or ranges, such as '1, 3, 5-10', in the Pages input field.

Does this tool support password-protected PDFs?

No, you must provide an unencrypted PDF file for the OCR process to function correctly.

Will the Markdown output include images from the PDF?

No, the tool focuses on converting text content and layout structure into Markdown text format.

Why should I keep line breaks in the output?

Keeping line breaks helps maintain the original visual structure of the document, which is useful for technical manuals or poetry.
