Lossless It : Music Converter

Is your "lossless" FLAC actually a re-encoded MP3? LosslessIt inspects the real spectrum on-device and shows you the truth in seconds.

Your music says "lossless" — but is it? A huge number of FLAC and "hi-res" files in the wild are fakes: an MP3 or AAC that was re-encoded into a lossless container. The file size looks right, the label says lossless, but the original detail is already gone. LosslessIt shows you the truth. LosslessIt inspects the actual audio signal on your iPhone — the real frequency spectrum, not the file extension — and tells you whether a track is genuinely lossless, a likely transcode, or native lossy. WHAT IT DOES • Frequency spectrum — see exactly where the audio cuts off. A hard shelf at 16–20 kHz is the fingerprint of a hidden MP3. • Transcode verdict — every track is scored: Lossless, Flagged (likely fake), or Native lossy, with a confidence level. • Real metrics — spectral cutoff, dynamic range, true peak, and estimated bitrate for every file. • Upgrade to ALAC — repackage eligible files to Apple Lossless (ALAC) in a tap. • Batch tools (Pro) — check and convert whole folders at once. 100% ON-DEVICE Every analysis and conversion runs entirely on your iPhone. LosslessIt never uploads your file names, your file paths, or your audio — to us or to anyone. There is no account and no login. What's on your phone stays on your phone. FOR AUDIOPHILES Whether you buy hi-res downloads, rip your own CDs, or trade files, LosslessIt is the honest second opinion that tells you what you're actually listening to — before you fill your library with fakes. FREE & PRO Analyze files for free. LosslessIt Pro is a one-time purchase — no subscription — that unlocks unlimited analysis, batch conversion, and deep metrics. An honest note: "Lossless It" changes a file's container to ALAC. It cannot restore detail that a previous lossy encode already discarded, and verdicts are best-effort estimates from signal analysis — accurate, but not a guarantee. See the spectrum. Trust your ears.
