Select page numbers or ranges before export. Images render each page into a separate file. Word and ebook exports reflow text; PowerPoint uses page images; spreadsheets estimate rows from text positions. Scanned pages need OCR, which is not available here.
Processing uses your device when possible and our servers when required. Browser files are limited to 256 MB each; server conversions to 64 MB; browser spreadsheets to 32 MB. Previews show supported content and do not guarantee identical rendering in every application.
