What happens when MPG becomes AAC
Source format
MPG is the video source or target format for this conversion path.
Target format
AAC is a lossy audio codec that is efficient at moderate bitrates.
What changes
The audio stream is decoded from the MPG container and encoded as AAC audio.
The video track, frames, subtitles, chapters, and visual metadata are not included in the audio output.
- What is preserved
- Audio duration and channel layout are preserved when the source stream and target codec support them.
- What may be lost
- All visual content is intentionally discarded.
- Codec and quality implications
- AAC uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the MPG source.
- Realistic limitations
- A MPG file with no decodable audio stream cannot produce AAC audio. Corrupt, encrypted, or unsupported codecs can also fail.
Conversion steps
- Upload a MPG file no larger than 1 GB.
- Confirm that AAC is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the AAC file and check the result before deleting your source.
Troubleshooting
- The MPG file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The AAC file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- The result has no sound or will not play.
- Try a broadly supported target codec and verify that the source contains a decodable audio stream.
Privacy and file retention
