Is there a file size limit?

We support files up to 200MB. Since all processing happens in your browser, larger files may take longer to convert depending on your device.

Which format should I choose?

MP3 is best for compatibility and small file size. WAV is uncompressed and great for editing. FLAC offers lossless compression for audiophiles. OGG and Opus provide excellent quality at small sizes.

Is my audio uploaded to a server?

No, all conversion happens locally in your browser using WebAssembly technology. Your files never leave your device, ensuring complete privacy.

What is the difference between lossy and lossless?

Lossy formats (MP3, AAC, OGG) compress audio by removing data, resulting in smaller files. Lossless formats (FLAC, WAV) preserve all audio data but create larger files. For most listening, lossy formats are indistinguishable from the original.
