    The converter is a one-time download of about 10 MB, which is why it isn't fetched until you ask for it. After that it stays cached. Everything runs on your device — the file is never uploaded, and conversion speed depends on your computer rather than a server.

    Lossless, and why it is inconvenient

    FLAC compresses audio without discarding anything — decode a FLAC and you get back the original samples exactly. It manages roughly half the size of a WAV, which makes it the standard for archiving and for people who buy music in high quality.

    Support is the catch. Many car systems, older iPods, some phones and a good deal of DJ and fitness equipment simply do not recognise FLAC. Converting to MP3 gives up the lossless property in exchange for playing more or less everywhere.

    This is the conversion that matters least

    Converting FLAC to MP3 is the one case where the usual warning about generation loss does not really apply. The source is lossless, so the encoder is working from the full original signal rather than from something already degraded — exactly the situation MP3 was designed for.

    At 320 kbps the result is about as good as MP3 gets. Listening tests consistently find that most people cannot reliably distinguish a well-encoded 320 kbps MP3 from its lossless source, even on good equipment.

    Keep the FLAC

    Because FLAC is lossless, it stays a perfect master no matter how many times you convert from it. You can produce an MP3 today, a different format in five years, and neither affects the original.

    So treat the MP3 as a disposable copy for a specific device, and keep the FLAC as the thing you actually own. Deleting the FLAC after converting is the one genuinely irreversible step here.

    Frequently asked questions

    Are my files uploaded to a server?

    No. The conversion runs inside your browser using your device's own processor. Your files are never transmitted anywhere, which is why the tool works even if you disconnect from the internet after the page loads.

    Will I hear a difference?

    At 320 kbps, almost certainly not. At 128 kbps you might on detailed music with good headphones — cymbals and reverb tails are where MP3 shows its limits first.

    How much smaller is the MP3?

    Typically 60–75% smaller. A 30 MB FLAC track usually becomes 7–11 MB depending on the bitrate.

    Can I convert a whole album at once?

    This tool takes one file at a time. Batch conversion for audio is on the list — the image tools already work that way.

    Is there a file limit or a paywall?

    There is no account, no watermark, and no upload cap. Because your device does the work, the only practical limit is your available memory. The site is funded by ads, not subscriptions.
