FAQ

Are files uploaded to any server?

Never. All conversion happens in your browser (client-side). Nothing is uploaded unless you explicitly share it.

What about DOCX/XLSX/EPUB conversion fidelity?

Basic conversions are done client-side using common libraries. Complex formatting may not be preserved perfectly. For best results, use simple documents.

Can I convert many files at once?

Yes — select multiple images and use the ZIP export to download all converted outputs in a single ZIP archive.
