Frequently Asked Questions

Can it extract text from scanned PDFs?

No, this tool extracts text only from text-based PDFs. For scanned documents, you need OCR (Optical Character Recognition) software.

Does it preserve formatting like tables?

Basic table structures may be preserved when "Preserve layout" is enabled, but complex formatting may not convert perfectly.

What's the maximum PDF size supported?

The tool can handle most PDFs, but very large files (500+ pages) may cause browser performance issues.

Can I convert password-protected PDFs?

No, this tool cannot process encrypted or password-protected PDF files.

Does it work with non-English PDFs?

Yes, it supports most languages that use standard Unicode character encoding.

How do I convert just one page of a multi-page PDF?

Uncheck "Convert all pages" and specify the page number in the pages field (e.g. "3" for page 3).
