FLAC to AIFF converter
Your FLAC goes in and an AIFF comes out. FLAC keeps every detail of the original recording while taking around half the space of a WAV, and it stores artwork and track information properly. Worth knowing: an AIFF will not open in a browser tab, so it is a file for software rather than for the web. Your file never leaves your computer.

How to convert FLAC to AIFF
- 1 Drop your FLAC .flac file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to AIFF, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the AIFF, or add more files and do the whole set in one go.
Why convert FLAC to AIFF
- Exactly as recorded, identical in quality to a WAV.
- Holds track details better than a plain WAV.
- Logic Pro and Pro Tools session assets.
- FLAC: wasted on speech and on recordings that were never good to begin with.

Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: AIFF stores the data without compression, so expect a much larger file.
- Browsers will not display an AIFF, so it downloads rather than opening in a tab.
- One AIFF limitation to keep in mind: less universally supported on Windows and web.
Questions about FLAC to AIFF
Is my FLAC file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your FLAC is read straight from your own disk, converted on your machine and handed back as an AIFF. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several FLAC files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate AIFF downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
