Does this tool preserve the original PDF layout?

No, it extracts clean plain text optimized for LLMs, intentionally stripping out visual layout elements while maintaining logical reading order.

Can I extract text from specific pages only?

Yes, you can use the Pages input to specify exact pages or ranges, such as '1,3,5-7'.

What does the sanitize sensitive data option do?

It automatically detects and masks sensitive information like personal identifiers or financial data before generating the final text file.

How does it handle headers and footers?

By default, headers and footers are removed to prevent repetitive noise in your LLM context, but you can choose to include them.

Why should I remove line breaks?

Removing hard line breaks joins fragmented sentences back together, which improves the semantic understanding and embedding quality for LLMs.
