Why convert OGV to MP4 (H.265)?
- Smaller files with MP4 (H.265) lossy compression.
- Keep animation and transparency where supported.

When not to convert OGV to MP4 (H.265)

- Keep a master copy: repeated exports stack small losses, so archive OGV before batch MP4 (H.265) shares.
Limits
Starting point: OGV - OGV carries Theora video with Vorbis audio in an Ogg container. Hardware support is thin, so convert for phones and editors. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from OGV at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
