Frequently Asked Questions
What audio formats can I compress?
We support MP3, WAV, AAC, OGG, and FLAC audio formats. All files are compressed and output as MP3 format for maximum compatibility across devices.
Which bitrate should I choose?
64kbps (low) is best for voice recordings and podcasts. 128kbps (medium) is recommended for most music and offers a good balance. 192kbps (high) provides better quality but larger file sizes.
Is my audio uploaded to a server?
No. All audio compression happens directly in your browser using WebAssembly. Your audio files never leave your device, ensuring complete privacy and security.

File size reduction depends on the original file and selected bitrate. You can typically reduce file sizes by 50-90%, especially when compressing high-quality WAV or FLAC files to MP3.
