Privacy-First Audio Converter & Editor

No, your files never leave your device. All audio processing happens entirely in your browser using WebAssembly technology (FFmpeg.wasm). This means complete privacy - we never see, store, or have access to your files.

AudioKit supports all major audio formats including MP3, WAV, FLAC, M4A, AAC, OGG, WMA, AIFF, and more. You can convert between any of these formats freely. For video extraction, we support MP4, AVI, MOV, MKV, and other common video formats.

There's no artificial file size limit imposed by AudioKit. The only limitation is your device's available memory. Since processing happens in your browser, larger files will take longer to process and require more RAM. Most devices can handle files up to several gigabytes.

Yes! AudioKit is a Progressive Web App (PWA) that works completely offline after your first visit. You can install it on your device and use all features without an internet connection. The first load requires internet to download the FFmpeg library (~30MB), but after that it's fully offline-capable.

AudioKit uses the same powerful FFmpeg engine that many desktop applications use, so the quality is identical. The main advantage is convenience - no installation required, works on any device, automatic updates, and complete privacy. For advanced audio production, desktop software may offer more features, but for conversion, trimming, merging, and compression, AudioKit is just as capable.

It depends on your use case: For podcasts and voice, 64-128 kbps MP3 is sufficient. For music listening, 192-256 kbps MP3 or 128 kbps AAC offers good quality. For archival or audiophile use, use 320 kbps MP3 or lossless formats like FLAC or WAV. AudioKit provides presets for common scenarios to make this easier.

Yes! The converter tool includes batch processing mode. You can upload multiple files, apply the same settings to all of them, and download the results as a ZIP file. This is perfect for converting entire music albums or podcast episodes at once.

The first time you use AudioKit, it needs to download the FFmpeg.wasm library (~30MB). This is a one-time download that gets cached in your browser. After that, all conversions are instant with no additional loading time. Think of it like installing desktop software, but automatic and much faster.

Absolutely. AudioKit is completely safe and secure. Since all processing happens in your browser, your files never leave your device - there's no server to be hacked or data breach to worry about. We don't collect any personal information, track your usage, or show ads. The source code is open and transparent.
