Choosing the perfect e-reader is one aspect, yet assembling your digital library is another. For those mindful of their budget, Libby and Stuff Your Kindle Day present opportunities to access a vast variety of books at no cost. If you already possess a collection of EPUB files to upload to your Kindle, the procedure is simple.

In the past, Kindles accepted a limited range of file formats, but as of 2022, they now accommodate EPUB files. You can transfer EPUBs to your Kindle via two methods: the Send to Kindle feature or the Calibre software. Both alternatives are user-friendly, and the selection depends on your inclination.

**Utilize Send to Kindle feature: The convenient choice**

**Total Time:** 5 minutes
**What You Need:** Computer

1. **Link your Kindle to Amazon:** Confirm your Kindle is linked to your Amazon account.
2. **Go to Amazon’s Send to Kindle page:** Navigate to the Send to Kindle page on Amazon’s website.
3. **Select your file:** Drag and drop your file or click “Select files from device” to upload your EPUB files to your Kindle.

Keep in mind that this method takes about five minutes per upload, which can be time-consuming for multiple files. If you prefer not to connect your Kindle to an Amazon account, you’ll need to utilize another approach for uploading EPUB files.

**Employ Calibre: The quickest method**

**Total Time:** 2 minutes
**What You Need:** Computer

1. **Obtain Calibre:** Access Calibre’s website to download the software for your device.
2. **Transform book:** Use the convert feature to choose a compatible format for your e-reader and change your EPUB file.
3. **Connect e-reader to device:** Attach your e-reader to your computer. A “device” icon will show up in Calibre, displaying your e-reader’s files.
4. **Transfer book into device library:** Drag your EPUB file to the device icon to upload it. Confirm the upload by inspecting the device library.
5. **Optional: Auto-convert:** If you forget to change your files, Calibre will prompt you to auto-convert when adding files to your device.

**The challenge of DRM files**

Calibre can transform files for most e-readers but cannot eliminate encryption from DRM files. E-reader brands typically encrypt books to stop them from being read on different devices. For instance, books purchased on a Kindle cannot be adapted for use on a Kobo. Although some services claim to decode these files, success is infrequent. Hence, these methods only function with unencrypted EPUB files.
