FLAC to MP3 Converter
Free online FLAC to MP3 converter. Drop your FLAC file, choose a bitrate and download an MP3 that plays anywhere — no upload, no software to install.
Why convert FLAC to MP3?
FLAC is a lossless compressed format — it keeps every detail of the original audio in a smaller file than WAV, popular for high-quality music libraries. FLAC files are large and not every device or app plays them. Converting to MP3 gives you a compact file that works everywhere, ideal for phones, cars and sharing. To convert, drop your FLAC file above, pick an MP3 bitrate and press Convert to MP3 — everything runs on your device with ffmpeg compiled to WebAssembly, so nothing is uploaded. A 3-minute FLAC is typically 15–20 MB; the same track at 192 kbps MP3 is about 4.3 MB — around four times smaller. Keep the FLAC as your archive copy: because it is lossless you can re-encode from it at any bitrate later, but you can never get detail back out of the MP3. Note that embedded cover art usually survives, while less common Vorbis comment tags may not carry across. Converting a different pair? Use the Audio Converter.
How to convert FLAC to MP3 in three steps
All three happen in your browser — nothing is uploaded.
- Load your FLAC. Drag a .flac file onto the box above, or click to choose one. CD rips, Bandcamp and HDtracks downloads and archived masters all work.
- Pick a bitrate and convert. Choose an MP3 bitrate between 96 and 320 kbps, then press Convert to MP3. The first conversion downloads the ffmpeg engine (about 10 MB); later runs start instantly.
- Preview and download. Play it back in the page, then download the .mp3 — and keep the original FLAC.
Which devices play FLAC, and which need MP3?
| Where you are playing it | FLAC | MP3 |
|---|---|---|
| Desktop players (VLC, foobar2000, Winamp) | Yes | Yes |
| Android phones | Yes, on most modern handsets | Yes |
| iPhone / iTunes library | Limited — needs a third-party app | Yes |
| Car head units and older stereos | Rarely | Almost always |
| Old iPods and cheap MP3 players | No | Yes |
| DJ software and hardware | Usually | Yes |
The short version: FLAC is the format to archive in, MP3 is the format to travel with. If a device or app has ever refused your music library, an MP3 copy at 256 to 320 kbps solves it at about a quarter of the size.
Frequently Asked Questions
How do I convert FLAC to MP3?
Drop your FLAC file onto the box above (or click to choose it), pick an MP3 bitrate, and press Convert to MP3. The MP3 is created on your device and a download button appears — no upload, no sign-up. The engine downloads once (about 10 MB) on the first conversion, and later runs start instantly.
Is this FLAC to MP3 converter free and private?
Yes — this FLAC to MP3 converter is free, with no sign-up and no watermark. The conversion runs entirely in your browser with ffmpeg compiled to WebAssembly — your FLAC file is never uploaded, logged or stored. That makes it safe for private recordings and music you own, and closing the tab clears everything.
Will converting FLAC to MP3 reduce the quality?
FLAC is lossless and MP3 is lossy, so this is the audio's first lossy compression. For archival keep the FLAC; for everyday listening MP3 at 256–320 kbps is near-transparent and far smaller. Picking 320 kbps from the bitrate menu keeps the most detail, 96 kbps the least.
What MP3 bitrate should I choose for a FLAC?
FLAC bitrate varies with the music, typically 700 to 1,100 kbps. Since the source is lossless you are choosing how much to give up: 320 kbps is the safe choice for a music library you actually listen to, and 192 kbps is fine for a car or a phone where you can always re-encode from the FLAC later. The menu also offers 96, 128 and 256 kbps when file size matters more than fidelity.
How big a FLAC can I convert?
FLAC files have no server-side size cap — the work happens in your browser tab, so the limit is your device's memory. Single tracks and most albums are fine; a very large lossless archive file may stall on a phone. You need a current Chrome, Edge, Safari or Firefox — the engine uses WebAssembly and DecompressionStream.
