About the FLAC to M4A Converter
This FLAC to M4A converter turns audio files from FLAC into M4A without installing software or uploading anything. It solves a common problem: FLAC files are big and many phones and car stereos will not play them. Converting to M4A gives you AAC audio in M4A for Apple devices, ideal for iPhone, iTunes and Apple Music libraries and voice memos.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your audio files are never uploaded, stored or seen by anyone else, which makes it safe for voice recordings, interviews and unreleased music.
What to expect: the sample rate and channels are kept, and you can pick the bitrate; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the FLAC to M4A Converter
- Click "Choose files" or drag your FLAC audio files onto the box. You can add several at once.
- Choose the M4A bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to M4A". The conversion runs on your device and shows its progress.
- Download each M4A file, or use "Download all (ZIP)" when you converted several.
- Open the result in iPhone or iTunes to check it; your original FLAC is never changed.
Tips & benchmarks
- AAC in M4A sounds better than MP3 at the same bitrate; 160–192 kbps is excellent for music.
- FLAC is lossless and M4A is not, so keep your original FLAC as the master copy and use the M4A for sharing.
- As a guide, one minute of audio at 128 kbps is about 1 MB, and at 320 kbps about 2.4 MB.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the M4A to a website or government portal.
Frequently asked questions
How do I convert FLAC to M4A?
Click "Choose files", select your FLAC audio files, adjust the options if you want, and press "Convert to M4A". The M4A downloads immediately; with several files you can download everything as one ZIP.
Is this FLAC to M4A converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your audio files never leave your phone or computer and nothing is stored on News Appite's servers.
Does converting FLAC to M4A lose quality?
M4A is a lossy format, so the audio is re-compressed. At 192 kbps or more most listeners cannot hear a difference from the source.
Can I convert several FLAC files at once?
Yes. Add as many FLAC files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed. The audio and video engine is a larger download the first time, so Wi-Fi is recommended.
What is the difference between FLAC and M4A?
FLAC (Free Lossless Audio Codec) is a lossless compressed audio best suited to lossless music libraries, hi-res downloads and archiving CDs. M4A (MPEG-4 Audio) is a AAC audio in an MP4 container best suited to iPhone, iTunes and Apple Music libraries and voice memos.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert FLAC to M4A without losing quality?
Pick 256 or 320 kbps. Re-encoding always loses a tiny amount of data, but at these bitrates the difference is inaudible for almost everyone.
