Frequently Asked Questions
What is the difference between lossy and lossless audio formats?
Lossy formats like MP3 and OGG permanently discard some audio data to achieve smaller file sizes, while lossless formats like WAV preserve every detail of the original recording. For casual listening, lossy formats at 192 kbps or higher are virtually indistinguishable from lossless.
Is my audio uploaded to a server during conversion?
No, all audio conversion happens entirely in your browser using the Web Audio API. Your files never leave your device, ensuring complete privacy for sensitive or personal recordings.
Why can I not convert to AAC or FLAC in the browser?
Browser-based conversion relies on the Web Audio API and MediaRecorder, which only support formats natively available in your browser. For AAC or FLAC output, desktop applications like Audacity or FFmpeg provide full codec support.
Which audio format offers the best balance of quality and file size?
MP3 at 192-256 kbps is the best all-around choice for music and general use. OGG Vorbis achieves slightly better quality at the same bitrate, but MP3 has universal device compatibility that OGG lacks.
Can I convert multiple audio files at once?
Yes, batch conversion is supported. You can add multiple files, choose your desired output format and quality settings, and convert them all simultaneously. Each file is processed independently in your browser.
