Convert OGV to Kindle Video — Free Online Converter

OGV uses Xiph.org's Theora video codec, which Amazon's Kindle Fire tablets cannot play. Kindle Fire runs Fire OS (Amazon's Android fork) with a media framework limited to standard Android codecs — H.264 and VP8 — excluding Theora. The Kindle Video preset produces MP4 with H.264 at parameters optimized for Kindle Fire's display and hardware decoder.

Kindle Fire tablets cannot decode Theora video. The built-in video player and Amazon's Silk browser reject OGV files entirely. Converting to the Kindle preset produces H.264 MP4 that plays natively on every Kindle Fire generation from the original (2011) through the latest models.

This conversion also optimizes resolution and bitrate for Kindle Fire's screen size (7-10 inches) and typically 16-32 GB storage capacity.
