Audio Converter

Our audio converter supports WAV, MP3, OGG, FLAC, AAC, M4A, AIFF, and WMA as input formats (depending on your browser's codec support). For output, you can convert to WAV (lossless), MP3 (universal compatibility), or OGG (open-source high quality). Chrome and Firefox typically support the widest range of input formats.

No — absolutely not. All conversion happens 100% locally in your browser using Web Audio API and JavaScript-based encoders. Your files never leave your device. This means complete privacy, no server costs, and no file size transfer limits beyond your device's memory. You can even use this tool offline once the page is loaded.

WAV is uncompressed and lossless — ideal for archiving, professional audio editing, or when you need the highest possible quality. File sizes are large.

MP3 is the most universally compatible format — great for sharing, web publishing, and portable devices. It uses lossy compression but at 192-320 kbps, quality loss is barely noticeable.

OGG (Vorbis) offers better sound quality than MP3 at equivalent bitrates and is fully open-source. It's excellent for game audio, streaming, and open-source projects. Most modern browsers and media players support it.

No. Once audio data is lost during lossy compression (like MP3 or OGG), it cannot be recovered. Converting MP3 to WAV simply preserves the existing quality in a larger container — it doesn't restore lost details. For the best quality, always start with a lossless source (WAV, FLAC, AIFF) and convert to your desired format.

While there's no hard server limit (since processing is local), we recommend keeping files under 200MB for optimal performance. Very large files may cause browser memory issues, especially on mobile devices. For files over 100MB, conversion may take longer and the page might become temporarily unresponsive during encoding. We display a warning for files exceeding 150MB.

128 kbps — Acceptable for speech, podcasts, and casual listening. Smaller file size.
192 kbps — Good balance of quality and size. Suitable for most music. (Recommended)
256 kbps — High quality, barely distinguishable from lossless for most listeners.
320 kbps — Maximum MP3 quality. Best for critical listening but larger files.

Currently, our tool processes one file at a time to ensure optimal performance and avoid browser memory overload. For batch conversion needs, you can process files sequentially — each conversion typically takes just seconds for average-length audio files. We're exploring batch processing for future updates.

OGG Vorbis encoding is computationally more complex than MP3 encoding, which can result in slightly longer conversion times. Additionally, our OGG encoder relies on a dynamically loaded JavaScript library, while MP3 encoding uses the highly optimized lamejs library. If OGG conversion is unavailable in your browser, try using Chrome or Firefox for the best experience.
