Frequently Asked Questions
What is the difference between WAV and MP3?
WAV is an uncompressed audio format that preserves every detail of the original recording, resulting in very large files. MP3 uses lossy compression to dramatically reduce file size while maintaining excellent audio quality for most listeners.
Will I lose audio quality converting WAV to MP3?
There is some quality reduction since MP3 is a lossy format. However, we use high-quality variable bitrate encoding (~190-250 kbps) which preserves excellent quality. For most use cases — podcasts, voiceovers, music sharing — the difference is barely perceptible.
How much smaller will the MP3 file be?
MP3 files are typically 80-90% smaller than WAV files. A 50 MB WAV recording might become 5-10 MB as an MP3. This makes MP3 far more practical for sharing, uploading, and storing audio.
Can I convert voice recordings and podcasts?
Yes! WAV is commonly used for recording audio. Converting to MP3 is ideal for podcasts, voiceovers, interview recordings, and voice memos that need to be shared or uploaded to platforms.
What is the maximum file size?
The maximum input file size is 200 MB. This covers most WAV recordings up to about 20 minutes of stereo audio at CD quality (44.1 kHz, 16-bit).
Is my audio file uploaded to a server?
No. All processing happens locally in your browser using WebAssembly technology. Your audio file never leaves your device, ensuring complete privacy.
