AIFF (.aiff) · Max 20 MB
The catch with most "free" converters shows up at the end: the download needs an account, a watermark tone is mixed into the audio, or your file waits in a queue behind paying users. None of that applies here. The engine is the same one Pro uses — same speed, same bitrate options — and the output is clean and unmarked.
Free also means free of the usual hidden cost: your file. Many no-cost converters are free precisely because your upload is the product. Here the conversion runs in your browser, so the AIFF never leaves your device. Given that AIFF files usually come from Logic Pro and GarageBand bounces, old iTunes rips, and Mac sample libraries, that's worth more than the price.
You won't save meaningful space — the two formats are within touching distance at 10–5 MB per minute. Lossless in, lossless out. The round trip is reversible, so convert as often as you like.
Free covers input files up to 20MB file size limit with a 10-second preview output, and 5 conversions per month. Pro removes those limits for full-length conversions up to 500MB file size limit — and the privacy behaviour is identical, because there was never a server in the loop.
The AIFF on your drive almost certainly started life in Logic Pro and GarageBand bounces, and AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. FLAC is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. You won't save meaningful space — the two formats are within touching distance at 10–5 MB per minute. Both AIFF and FLAC are lossless, so this specific conversion is bit-perfect: every sample survives and you can go back to AIFF later without any loss.
Frequently Asked Questions
Is this AIFF to FLAC converter really free?
Yes — no watermark, no signup, no queue. Free covers files up to 20MB file size limit, 5 conversions per month, and a 10-second preview output. Pro removes those caps; the engine and audio quality are identical on both tiers.
What's the catch with free converters?
Usually one of four: a watermark tone in the audio, a forced account before download, a throttled queue behind paying users, or your file quietly becoming the product on someone's server. None apply here, because the conversion never leaves your machine.
Do I need an account to download the FLAC file?
No. The file downloads straight from your browser the moment conversion finishes — it never went anywhere, so there's nothing to gate behind a login.
Is the free output lower quality?
No. Free and Pro use the same encoder and the same bitrate options. Quality is never the paywall — the free tier limits length and file size, not fidelity.
How much smaller or larger will the file be?
You won't save meaningful space — the two formats are within touching distance at 10–5 MB per minute.
