Convert AIFF to FLAC
Convert AIFF to FLAC on your device. Choose your file, convert, and check the result before sharing.
Drop your .aiff here

Processed on your device - nothing is uploaded.
HOW IT WORKS
1
Drop the aiff file
Drag your AIFF onto the page or click to browse. It is read locally, never sent anywhere.
2
Choose FLAC
FLAC is lossless, so there is no quality or bitrate menu. Click Convert to start processing in this tab.
3
Save the flac
The finished FLAC downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Server converters receive your aiff on their disk. This one reads it in your browser and nowhere else.
Local conversion
The flac starts encoding the moment you drop the file - there is no upload phase at all.
No account, no daily cap
Convert every aiff you own, free. Nobody meters you, nobody asks for an account.
The two formats, briefly
| AIFF | AIFF is an audio container. This converter writes 16-bit PCM audio; a higher-bit-depth source can lose precision. | |
|---|---|---|
| FLAC | FLAC uses lossless audio compression. Encoding decoded audio as FLAC does not restore detail already lost in a source recording. | |
When you need this
- Use FLAC when your player or archive needs losslessly compressed audio. Converting AIFF to FLAC cannot recover detail missing from the source; compare output size rather than assuming it shrinks.
AIFF vs FLAC: what changes
| AIFF | FLAC | |
|---|---|---|
| Kind | Audio | Audio |
| Compression | 16-bit PCM output here | Lossless audio compression |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | FLAC workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- FLAC uses lossless compression of decoded audio. There is no bitrate choice, and lossy source detail cannot be recovered.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
AIFF to FLAC, answered
Why convert AIFF to FLAC?+
Use FLAC when your player or archive needs losslessly compressed audio. Converting AIFF to FLAC cannot recover detail missing from the source; compare output size rather than assuming it shrinks.
Which quality should I pick?+
FLAC uses lossless compression of decoded audio. There is no bitrate choice, and lossy source detail cannot be recovered.
Does converting AIFF to FLAC lose quality?+
FLAC losslessly encodes decoded audio, but decoding and supported sample precision still matter. It cannot restore missing detail, preserve the video picture, or promise every source track and metadata field survives.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
No upload, full stop. Everything between dropping the file and downloading the flac happens in your browser.
