Frequently asked questions
How much can I boost the volume of an audio file?
Use the Volume Boost slider to increase gain up to 300% of the original. Moderate boosts (up to 200%) preserve audio quality well. Higher boosts on loud tracks may introduce clipping, which is normal.
What file formats does the volume booster support?
MP3, WAV, OGG, M4A, and AAC files. The output is a downloadable WAV or MP3 file depending on your export setting.
Does boosting volume reduce the audio quality?
At up to 200% boost, quality is well-preserved. At 300%, very loud sections may clip slightly. You can use Fade In/Fade Out to smooth the transition.
Is this tool free and safe to use?
Yes — 100% free, no account needed, and your audio file never leaves your device. All processing is local in your browser.
Can I boost the volume of a voice recording or podcast?
Absolutely. This is the most common use — boosting quiet microphone recordings, lectures, and podcasts to a listenable level.
