Does Kindle Oasis support EPUB files?

Yes, since firmware update 5.16 released in 2022. Both Kindle Oasis 2 (2017) and Oasis 3 (2019) support EPUB natively — you can send EPUB files directly via Send to Kindle or USB without converting to MOBI or AZW3 first. The Oasis was Amazon's flagship reading device before it was discontinued in 2023; both generations remain fully supported with software updates and EPUB via Send to Kindle.

How do I send an EPUB to my Kindle Oasis?

Three methods: (1) Send to Kindle email — find your @kindle.com address in Settings → Your Account → Send-to-Kindle Email; email the EPUB as an attachment; (2) Send to Kindle app — install on Mac, Windows, iOS, or Android; drag the EPUB in and select your Oasis; (3) USB cable — connect with the supplied Micro-USB cable (Oasis 2) or USB-C (Oasis 3); drag the EPUB to the Documents folder on the Kindle drive.

What makes Kindle Oasis different from Paperwhite for EPUB reading?

Kindle Oasis has a 7-inch 300 ppi display (vs Paperwhite 5's 6.8 in), physical page-turn buttons on the right side for ergonomic one-handed reading, an aluminium body, and an auto-rotating display. Oasis 3 adds a warm/cool frontlight. Both read EPUBs identically — the Oasis advantage is the larger screen, physical buttons, and premium build. The Oasis was discontinued in 2023; new buyers must find refurbished or second-hand units.

Can I adjust font and typography on Kindle Oasis for EPUB reading?

Yes, the same as all modern Kindles. Tap the top of the screen → Aa to access font settings: font size (14 steps), typeface (Bookerly, Amazon Ember, Caecilia, Palatino, etc.), line spacing (3 options), margins (3 options). Oasis 3 adds the warm/cool frontlight slider. The 7-inch screen gives slightly more text per page at the same font size versus the 6.8-inch Paperwhite 5.

Is Kindle Oasis still worth buying for EPUB reading in 2026?

If you can find a good-condition refurbished Oasis 3 at a fair price, it remains excellent — the 7-inch screen, physical buttons, and premium build are genuinely better for long reading sessions. However, Amazon no longer sells it new. The Kindle Paperwhite 5 (6.8 in, USB-C, warm/cool light) is the natural alternative at a lower price. For annotation needs, consider Kindle Scribe or Kobo Sage instead.
