Frequently Asked Questions
Are my documents sent to a server?
Never. Document conversion runs client-side with pdf-lib, PDF.js, mammoth.js and SheetJS. Your files never leave your browser.
Which document formats are supported?
PDF, DOCX, XLSX, PPTX, TXT, HTML, CSV, JSON, XML and Markdown, across many conversion directions.
Can I convert a PDF to an editable Word file?
Yes, for text-based PDFs. Scanned PDFs need OCR, which is not yet supported.
