Frequently Asked Questions

How does audio compression work?

Audio compression reduces file size by lowering the bitrate and removing inaudible frequencies. The tool uses advanced algorithms to compress audio while preserving quality. Lower bitrates (64-96kbps) create smaller files suitable for voice, while higher bitrates (192-320kbps) maintain better quality for music.

What bitrate should I choose for audio compression?

Choose 64-96kbps for voice recordings and podcasts, 128kbps for standard music quality with balanced file size, 192-256kbps for high-quality music, and 320kbps for maximum quality near-CD audio. The bitrate determines both file size and audio quality.

Which audio formats can I compress?

The audio compressor supports all common formats including MP3, WAV, AAC, OGG, FLAC, M4A, and more. Simply upload your audio file and select your desired compression bitrate to reduce file size while maintaining quality.

Will compression reduce audio quality?

Some quality loss occurs during compression, but our tool uses intelligent algorithms to minimize it. Higher bitrates (192kbps+) preserve excellent quality suitable for music. For voice content, lower bitrates (64-128kbps) still maintain clear, understandable audio while significantly reducing file size.

Is my audio file safe when using this compressor?

Yes! All compression happens locally in your browser using client-side JavaScript. Your audio files never get uploaded to any server or transmitted anywhere. Your files remain completely private and secure on your device throughout the entire compression process.

How much can I reduce audio file size?

File size reduction depends on the original format and target bitrate. Compressing a high-quality WAV to 128kbps MP3 can reduce size by 80-90%. Compressing an existing MP3 to a lower bitrate typically achieves 30-70% size reduction. The tool displays exact compression results after processing.

Can I compress multiple audio files at once?

Currently, the tool processes one audio file at a time to ensure optimal quality and performance. After compressing a file, you can immediately upload and compress another file. The compression process is fast, typically completing in seconds.

Is there a file size limit for audio compression?

There is no strict file size limit for audio compression since all processing happens in your browser. However, very large files (over 100MB) may take longer to process and require more browser memory. For best performance, files under 50MB are recommended.
