About YUV to MP4 (H.265)
Convert YUV to MP4 (H.265). YUV holds raw planar pixels with no container or compression. MP4 (H.265) stores HEVC video, cutting bitrate roughly in half versus H.264. HEVC decoding needs newer hardware and encodes more slowly..
Why convert YUV to MP4 (H.265)?
- Smaller files with MP4 (H.265) lossy compression.
- Keep animation and transparency where supported.
- Private, no upload - runs in your browser.
YUV vs MP4 (H.265)
| Animation | Yes | Yes |
|---|---|---|
| Transparency | No | No |
| Compression | uncompressed | lossy |
| Typical use | YUV holds raw planar pixels with no container or compression. | MP4 (H.265) stores HEVC video, cutting bitrate roughly in half versus H.264. |
When not to convert YUV to MP4 (H.265)
- Skip MP4 (H.265) for archival masters: lossy compression discards detail, so keep the YUV original.
- Keep a master copy: repeated exports stack small losses, so archive YUV before batch MP4 (H.265) shares.
Limits
Starting point: YUV - YUV holds raw planar pixels with no container or compression. Dimensions must be set by hand since headers carry no size. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from YUV 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.
