What is Audio Converter?
Audio Converter is a free online audio tool from Farvixo that lets you AI-powered audio converter — batch upload, smart analysis, studio presets, noise removal & 15+ formats. Decoding and encoding both happen in your browser through WebAssembly, so recordings, interviews and voice notes never reach a server. Free and unlimited, with no watermark or audible tag added to the output.
How to use Audio Converter
Add an audio file to Audio Converter. Processing runs locally in your browser, so your recordings are never uploaded.
Pick the format, bitrate and sample rate you need, or use a preset tuned for music, podcasts or voice notes.
Convert and download the finished file. Quality is yours to control and nothing is added to the output.

Is my audio uploaded to a server?
No — 100% browser processing with FFmpeg WebAssembly. Your files never leave your device.
What are the quality presets?
Balanced, Lossless, High Quality, Mobile, Streaming, Podcast Ready, and Studio Quality — each tuned for different use cases.
Does AI analysis help?
Yes — detects bitrate, loudness, clipping, noise, voice vs music, BPM, and suggests optimal format and enhancement settings.
Can I remove background noise?
Yes — enable AI Noise Removal, Voice Enhancement, Silence Removal, and Loudness Optimization in the AI Enhancement panel.
Can I record audio directly?
Yes — use Record Mic to capture from your microphone, then convert to any format.
Can I convert multiple files?
Yes — unlimited batch upload with queue manager. Download individually or as ZIP with full audio report.
Can I merge multiple tracks?
Yes — enable "Merge all files into one audio track" when you have 2+ files in the queue. FFmpeg concatenates then converts in one pass.
Does it have a waveform editor?
Yes — after analysis, drag trim handles on the interactive timeline to set start/end points. Spectrum analyzer shows frequency distribution.
Can I edit ID3 metadata and album art?
Yes — use Metadata & Album Art panel to set title, artist, album, genre, and embed cover images into MP3/M4A output.

Tips for better results
- Speech is fine in mono — downmixing halves the file size with no perceptible loss on voice content.
- For spoken word, 64–96 kbps is transparent; music generally needs 128 kbps or more.
- Every lossy re-encode loses information. Always start from the highest-quality original you have, not from a file you already compressed.
Common problems and how to fix them
The file will not load
The container is fine but the codec is unusual, or the file is partially downloaded. Re-download the original and try again.
The output sounds thin or watery
The bitrate is too low for the material. Raise it a step, and keep stereo if the source is music rather than speech.
Volume is inconsistent across the file
Enable loudness normalisation, which levels the track to a single EBU R128 target instead of leaving the peaks and quiet passages as they were.
