Frequently Asked Questions

Does this work with Word documents or PDFs?

For complex formats like DOCX or PDF, use the "paste content" mode. The converter works best with plain text formats that can be processed directly in the browser.

Are my files uploaded to a server?

No, all processing happens locally in your browser. Files never leave your computer.

What's the maximum file size?

Large files may slow down your browser. We recommend files under 10MB for optimal performance.

How It Works

• Files are read using FileReader API and processed locally
• Find/replace operations use JavaScript String methods
• Results are packaged using Blob API for download
• Print to PDF uses your system's print dialog

For informational and educational purposes only. Conversions run locally in your browser. Complex formats may be partially supported. Verify formatting and compliance before professional use.
