EPUBKit is your go-to platform for free, fast, and secure online EPUB conversion. We believe ebook format conversion should be simple and accessible to everyone, whether you are on a desktop, tablet, or mobile device.
We built EPUBKit to solve a real problem: converting between ebook formats used to require installing desktop software or paying for online services. We changed that.
We also wanted to fix the most annoying step for Kindle readers: getting the converted file onto the device. That is why EPUBKit includes a Send to Kindle button that delivers your converted file wirelessly to your Kindle in one click.
Every tool works online, on any device, with no software to install.
EPUBKit is built and maintained by an independent developer based in Spain. It runs on open-source conversion technology (Calibre) and is kept free thanks to advertising. There is no company behind it collecting your data — just a small tool made to be useful.
All files uploaded to EPUBKit are processed securely and deleted automatically after 1 hour. We do not store, read, or share your files or personal data. For full details, please read our Privacy Policy.
