eBook Converter Online
Convert an EPUB, DOCX, ODT, RTF, or TXT file directly in your browser, without uploading your file to a server. Paragraph text and headings are preserved.
What this tool does
NexKit eBook Converter reads an EPUB, DOCX, ODT, RTF, or TXT file directly in your browser and rebuilds it in the target format you choose. Paragraph text and heading levels are preserved, including EPUB chapters read in their original order.
This tool does not preserve cover images, embedded images, CSS styling, or fonts - only paragraph text and headings carry over. MOBI is not supported - no viable browser-based library exists for this legacy Amazon format. For PDF conversions, use the dedicated PDF to Word, Word to PDF, PDF to Excel, Excel to PDF, PDF to PowerPoint, or PowerPoint to PDF tools instead.
