File & eBook Tools

Digital formats can be restrictive. You bought the book, but you can only read it on one specific device. Our File & eBook Tools are here to break down those barriers.

We specialize in secure, client-side conversions. This means if you are converting a sensitive document or a copyrighted personal backup of an eBook, it never leaves your computer. The conversion happens right in your browser memory, ensuring total privacy.

Our AZW3 to EPUB Converter is specifically designed for readers who want to enjoy their Kindle library on non-Amazon devices. AZW3 (Kindle Format 8) is Amazon's proprietary format that works great on Kindle but fails to open on Kobo, Nook, Apple Books, or most other e-readers. By converting to EPUB—the universal standard supported by 95% of reading apps—you unlock true device freedom.

Important note: This tool only works with DRM-free books. If you've purchased books from Amazon with DRM protection, they're encrypted and cannot be converted legally without authorization. However, public domain books, personal manuscripts, and DRM-free purchases convert flawlessly. Once converted, you can also use our PDF Compressor if you later export your ebooks to PDF format for archival purposes.

The conversion process preserves your book's original formatting including chapter divisions, table of contents, embedded images, and font styling. For readers building personal digital libraries across multiple platforms, this tool is essential for maintaining access to your collection regardless of which device you're using today or might switch to tomorrow.

All conversions happen entirely in your browser using advanced JavaScript libraries. No file uploads, no server processing, no data retention. We literally cannot access your files even if we wanted to—that's how client-side processing works, and it's the foundation of our privacy guarantee.
