Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your EPUB e-books into the RTF document format effortlessly. This tool is ideal for users who need to move reading material into word processors for further editing or formatting.
EPUB is a specialized container format designed for digital publications, using HTML and CSS structure to maintain reflowable text. In contrast, RTF (Rich Text Format) is a universal document format supported by virtually every word processor, including Microsoft Word and LibreOffice. When converting from EPUB to RTF, the structure of the document is mapped into RTF control words, effectively translating web-based book styling into a desktop-native document format.
The conversion maintains complete data integrity, ensuring that no text or formatting information is lost during the transition between these two document formats.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
