Pros and limits of online editing
Pros
- No install — works on any device with a browser.
- Files stay in your browser, so there are no privacy concerns.
- Simple tasks (cut, merge, convert) are fast and easy.
Limits
- Multi-track mixing is better handled by a desktop DAW.
- VST plugins are not supported.
- Very long files (over 1 hour) may slow down due to browser memory limits.
Recommended workflow order
When chaining several edits, follow this order for the best results:
- Noise removal — clean up background noise first.
- Cut & merge — keep only the sections you need.
- Fades & silence trimming — smooth the start and end.
- Volume adjustment — set the right loudness.
- Convert & export — save in the format you need (MP3, WAV).

FAQ
What can an online audio editor do?
View the waveform and cut, merge, adjust volume, add fade in/out, remove noise and convert formats — all basic audio editing tasks.
Do I need to install Audacity?
For simple edits, an online tool like FreeSoundTools is enough. For multi-track mixing or VST plugins, a desktop app like Audacity or Reaper is better.
Are my files uploaded to a server?
No. All FreeSoundTools audio tools run in your browser and never send files to a server.
