About HEVC to MP4 (H.265)
Convert HEVC to MP4 (H.265). HEVC is the H.265 codec halving bitrates versus H.264. 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 HEVC to MP4 (H.265)?
- Smaller files with MP4 (H.265) lossy compression.
- Keep animation and transparency where supported.
- Free, private, no upload - runs in your browser.
HEVC vs MP4 (H.265)
| Animation | Yes | Yes |
|---|---|---|
| Transparency | No | No |
| Compression | lossy | lossy |
| Typical use | HEVC is the H.265 codec halving bitrates versus H.264. | MP4 (H.265) stores HEVC video, cutting bitrate roughly in half versus H.264. |
When not to convert HEVC to MP4 (H.265)
- Skip MP4 (H.265) for archival masters: lossy compression discards detail, so keep the HEVC original.
- Keep a master copy: repeated exports stack small losses, so archive HEVC before batch MP4 (H.265) shares.
Limits
Starting point: HEVC - HEVC is the H.265 codec halving bitrates versus H.264. Raw streams lack timing, so set frame rate by hand. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from HEVC 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.
