Are files uploaded?
Conversion happens locally, without file uploads. Website analytics and remote images in documents may make network requests; see the privacy policy.
Will every format feature be preserved?
Features depend on the target format. CSV has no styles or multiple sheets; Markdown tables have no merged cells or formula calculation. Inspect mappings and notices before export.
How large can my files be?
Capacity depends on your device, content and decompressed size. Tools show resource budgets and preview ranges. Limited previews do not truncate accepted export data.
