Convert FLAC to MP3 online
Conversion runs on our servers using ffmpeg, so you get reliable encoding for both lossy (smaller files, e.g. MP3, AAC, Opus) and lossless (FLAC, WAV) workflows. You can fine-tune bitrate, sample rate, and mono or stereo when you need a specific size or quality. Maximum upload size is 25MB per file.

Common questions
What audio formats can I convert?
You can export to MP3, WAV, AAC, M4A, FLAC, OGG, OGA, Opus, WebM (audio), and WMA. Pick the one that matches your goal: MP3 and AAC for wide compatibility, FLAC or WAV for quality, Opus and WebM for efficient web and voice audio.
Is this audio converter free?
Yes—you can convert audio online without a subscription. Limits (such as 25MB per file) keep the service fast and fair for everyone.
Will my file sound worse after conversion?
Moving to a lossy format (like MP3 or AAC) always involves some compression. Use a higher bitrate or a lossless output (FLAC, WAV) when quality matters most. Re-encoding the same lossy format repeatedly can add artifacts, so prefer converting once from your best source file.
Why use Opus or WebM instead of MP3?
Opus and WebM (with Opus audio) often produce smaller files at similar perceived quality—useful for podcasts, voice notes, and streaming. MP3 remains the safest choice when you need maximum device support.
Quick tips
Choosing a format
Smallest size for speech or web: Opus, WebM, or AAC. Best compatibility: MP3. Archiving masters: FLAC or WAV.
Opus and WebM quality
For these outputs, bitrate drives quality—raise it for music, lower it for speech-only clips to save space.
