How to Use FreeAudioKit

Steps

1. Open Audio Converter from the navigation.
2. Upload the source audio file.
3. Choose one or more supported output formats.
4. Pick a quality preset based on your workflow.
5. Download the first selected output or all selected formats.
6. Use the exported version that best fits editing, playback, or sharing.

Tips

• WAV is best for editing and highest quality preservation.
• Compressed formats are better for quick sharing and smaller downloads.
• Download all selected outputs when you want one master file in multiple delivery formats.
• Use Audio Compressor after conversion if file size is still too large.

Steps

1. Open Audio Compressor from the navigation.
2. Upload the audio file you want to shrink.
3. Choose the compressed output format your browser supports.
4. Pick a preset like Sharing, Voice, Balanced, or Smallest.
5. Compress and download the smaller file.
6. Try another preset if you want a better quality-size tradeoff.

Tips

• Voice is great for lectures, voice notes, and podcasts.
• Sharing is the safest everyday default.
• Smallest is useful when upload limits are strict.
• Use Video to Audio first when the source is a video file.

Steps

1. Open Video to Audio from the navigation.
2. Upload a video file such as MP4 or WebM.
3. Review the video preview and choose an audio output format.
4. Run extraction in the browser.
5. Download the audio-only file.
6. Move into Compressor, Converter, or Trimmer if you want more cleanup after extraction.

Tips

• This is useful for lectures, interviews, and social clips where you only need the sound.
• WAV is useful when you plan to edit the extracted audio further.
• Compressed outputs are better for faster sharing.
• If extraction fails, try another video container or browser-supported export format.

Steps

1. Open the Audio Trimmer from the navigation bar.
2. Upload an audio file by clicking the upload area or dragging a file.
3. The waveform appears — drag the start and end handles to select a region.

6. Click Export to download the trimmed audio as WAV.

Tips

• Drag handles on the waveform for visual trimming.
• The timeline shows the exact position in minutes and seconds.
• Preview plays only the selected region.
• Works with any audio format your browser supports.

Steps

1. Open the Volume Adjuster from the navigation bar.
2. Upload an audio file.
3. View the peak amplitude and RMS level.
4. Drag the volume slider (0% to 200%) to adjust.
5. Click Normalize to automatically optimize volume.
6. Preview and download the adjusted audio.

Tips

• Normalization brings the loudest peak to maximum without clipping.
• Use 50% to halve the volume, 200% to double it.
• The dB meter shows the change in real time.
• Useful for matching volume levels across multiple files.

Steps

1. Open the Audio Merger from the navigation bar.
2. Upload two or more audio files.
3. Drag files to reorder them.
4. Click Merge to combine all files into one.
5. Preview the merged result.

Tips

• 1.5x - 2x is ideal for podcast and lecture speed-up.
