Quick tips
- 10MB is reasonable for voice.
- Music depends heavily on duration.
- Target Size mode estimates bitrate from the full length.
How to use
- Choose Target Size mode and set 10MB, or slightly lower if the upload system is strict.
- For files under 5 minutes, test 128 kbps if quality matters.
- For 10-20 minute voice recordings, use mono and 64-96 kbps.
- Preview the result because a 10MB music file can vary from acceptable to thin depending on length.
Recommended settings
| Duration | Suggested approach |
|---|---|
| Under 5 min | 128 kbps may fit |
| 5-10 min | 96-128 kbps |
| 10-20 min voice | 64-96 kbps mono |
| Long music file | 10MB may be too small |
Supported formats
MP3 is the most predictable 10MB output for forms and sharing.
AAC/M4A can be efficient for mobile recordings; use OGG mainly for web or project assets.
Quality vs file size
A 10MB target balances size and quality better than 5MB, but it still depends on duration.
The tool estimates bitrate from target size and length. Container overhead can make the final file slightly above or below 10MB.
Privacy and local processing
Compression runs in your browser, so the original audio is not uploaded to a server.
Large files can still be slow because decoding and encoding use your device memory and CPU.
Things to watch
- Do not assume 30 minutes of stereo music can fit under 10MB with good quality.
- Leave margin for strict uploaders.
FAQ
How do I compress audio to exactly 10MB?
Use Target Size mode, but exact size is not guaranteed because encoding overhead varies.
What bitrate should I use for 10MB?
For 5-10 minutes, 96-128 kbps is common; for longer voice, use 64-96 kbps mono.
Can a 30-minute recording fit under 10MB?
A voice recording may fit with low mono bitrate. Music is usually not a good match.
Why is the output slightly above 10MB?
Metadata and encoder overhead can add a little size. Target slightly below 10MB.
Is 10MB enough for music?
For short clips, yes. For long songs or mixes, it may require too much quality loss.
