Turn your FLAC audio files into MP3 in seconds — free, private and entirely in your browser. Nothing is ever uploaded to a server.
Open the Audio Converter
Go to the DefyAudio Studio — the FLAC to MP3 converter runs right in your browser.
Add your FLAC file(s)
Drag and drop or browse for your FLAC file. Add several at once to batch-convert them all to MP3.
Choose MP3 as the output
Select MP3 in the Format tab. Pick the bitrate that fits your quality/size trade-off.
Adjust quality (optional)
Fine-tune sample rate, channels and bit depth if you need a specific spec — otherwise the defaults are ready to go.
Convert and download
Click Convert. Your MP3 file is processed locally and downloads instantly — no data leaves your device.
FLAC is lossless and large; converting FLAC to MP3 makes your library portable and streaming-friendly at a fraction of the size. Pick 320 kbps for near-transparent quality, or a lower bitrate when space matters most.
Open DefyAudio's converter, add your FLAC file, select MP3 as the output format, and click Convert. The MP3 file downloads instantly — free, with no upload.
Converting to MP3 re-encodes the audio; choose a higher bitrate to keep quality close to the source. DefyAudio lets you pick the exact bitrate before converting.
No. All conversion happens locally in your browser — your files never leave your device.
Yes. Add multiple FLAC files and DefyAudio batch-converts them all to MP3 in one pass.
