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 PPTX slide decks effortlessly. This tool is perfect for educators and speakers who need to turn digital reading materials into structured presentation slides.
EPUB is a reflowable document format designed primarily for digital reading, while PPTX is a fixed-layout format optimized for visual presentations. During the conversion process, our system maps the chapters, headings, and textual content of your e-book into distinct slides, ensuring the logical structure of your document is preserved within the PowerPoint architecture.
The conversion is lossless, meaning all text content remains intact and sharp. Since both are document-oriented formats, the overall data fidelity is maintained with only minor adjustments to file size.
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.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
