Need help?How to Convert HEVC to AAC
- Upload Your HEVC File — Click "Choose Files" or drag and drop your HEVC (H.265) video file. Only HEVC files are accepted as input.
- Adjust Audio Quality — Under File Compression, choose a Quality Preset (Highest through Lowest), set a Constant Bitrate (e.g., 128 kbps, 192 kbps, 256 kbps), enter a Custom Bitrate in kbps, or specify an exact file size in MB/KB.
- Configure Audio Options (Optional) — Set Audio Channel to Mono or Stereo, and adjust the Audio Sample Rate (8000 Hz, 44100 Hz, or 48000 Hz). You can also trim the audio by setting a Start Time and Duration under the Trim section.
- Convert & Download — Click "Convert" to extract the audio track as an AAC file. Download instantly.
Why Convert HEVC to AAC?
HEVC (High Efficiency Video Coding, also known as H.265) is a video compression standard used for 4K streaming, Blu-ray, and modern smartphone recordings. AAC (Advanced Audio Coding) is the successor to MP3, offering better sound quality at the same bitrate. Converting HEVC to AAC extracts just the audio track from your video, which is useful for saving music from concert recordings, extracting dialogue from video interviews, creating podcast audio from video content, or reducing file size when you only need the sound.
AAC Bitrate Guide
| Bitrate | Quality | File Size (per min) | Best For |
|---|---|---|---|
| 64 kbps | Low | ~0.5 MB | Voice recordings, podcasts |
| 128 kbps | Good | ~1 MB | General listening, audiobooks |
| 192 kbps | High | ~1.4 MB | Music, high-quality podcasts |
| 256 kbps | Very High | ~1.9 MB | Critical listening, archival |
| 320 kbps | Maximum | ~2.4 MB | Studio-quality preservation |
HEVC vs AAC Comparison
| Property | HEVC (H.265) | AAC |
|---|---|---|
| Type | Video codec | Audio codec |
| Compression | Lossy video | Lossy audio |
| Typical file size (5 min) | 50-200 MB | 3-10 MB |
| Device support | Modern devices, 4K TVs | Nearly universal |
| Primary use | 4K/8K video streaming | Music, streaming, mobile |
Does converting HEVC to AAC lose quality?
Some quality loss is inherent when re-encoding audio to AAC since it uses lossy compression. To minimize this, use a higher bitrate — 192 kbps or 256 kbps is recommended for music. If the original HEVC file already contains an AAC audio track, the tool re-encodes it, so using the highest quality preset preserves the most fidelity.
What bitrate should I choose for music extraction?
For music, 192-256 kbps provides excellent quality that most listeners cannot distinguish from the original. For voice-only content like interviews or podcasts, 128 kbps is sufficient. You can set this via Constant Bitrate (preset dropdown) or Custom Bitrate (enter any value in kbps).
Can I trim the audio while converting?
Yes. Under the Trim section, switch from "Unchanged" to "Trim" and set a Start Time and Duration. Times can be entered in seconds or HH:MM:SS.sss format. This lets you extract only the portion of audio you need without a separate editing step.
What audio channels does the output support?
You can output as Mono (single channel), Stereo (two channels), or keep the original channel layout. Stereo is the default and recommended for most use cases. Mono is useful for voice recordings where file size matters.
Is AAC better than MP3?
AAC generally provides better audio quality than MP3 at the same bitrate, especially below 128 kbps. AAC is the default audio format for YouTube, Apple Music, and most streaming services. It is natively supported on iOS, Android, Windows, and macOS.
