Does converting FLAC to M4A lose audio quality?

Yes. FLAC is lossless, while M4A (AAC) is lossy. At 192 kbps AAC, most people will not hear a difference, but some details are discarded. Once converted, you cannot recover the lost fidelity. For archiving or editing, keep the original FLAC.

How much smaller is M4A than FLAC?

A typical 4-minute stereo FLAC song is 25–30 MB. The same file as M4A at 192 kbps is about 5.5–6 MB — roughly 80% smaller. Higher bitrates make the M4A a bit larger, lower bitrates make it smaller but may reduce quality.

Can I play FLAC files on my iPhone?

Not natively. iOS and iTunes do not support FLAC out of the box. You need a third-party player app or convert FLAC to M4A (AAC) or MP3 for playback in the built-in Music app.

What bitrate should I pick for AAC/M4A?

192 kbps AAC is a good compromise for music: small files and transparent quality for most listeners. For speech, 96–128 kbps is fine. For high-fidelity music, 256–320 kbps gets you closer to lossless, but files are bigger.

Will converting to M4A keep my tags and artwork?

Videozify preserves standard metadata (title, artist, album) if present. However, some advanced tags or embedded artwork may be lost or not display in all players. For complex tagging, check the output in your music library app.

Is there a way to convert FLAC to M4A on Windows or Mac without extra software?

Not directly. Windows Media Player and macOS Music/iTunes do not import FLAC. You would need to use a tool like VLC or Audacity (with FFmpeg) to first convert FLAC to WAV, then import into iTunes to convert to AAC/M4A, which is more work than using a browser-based tool.

Should I delete my FLAC files after converting to M4A?

Keep your FLAC originals if you might ever want to re-convert at a higher quality, edit the audio, or archive your collection. M4A is fine for daily listening, but cannot be converted back to lossless. Storage is cheap; backups are safer.

Can I convert multiple FLAC files at once?

Videozify processes one file at a time to avoid memory issues in your browser. For a batch of songs, convert and download each, then repeat. For large collections, desktop batch tools like fre:ac or XLD (Mac) are faster, but require installation.

A FLAC to M4A converter turns a lossless FLAC audio file into a compressed M4A file using the AAC codec. Videozify drops any video track, encodes the audio to AAC at your chosen bitrate (default 192 kbps), and saves it as M4A. This shrinks file size for easier sharing or playback on phones and apps that do not support FLAC.

How to convert FLAC to M4A

Drop your FLAC file onto the box above, or click Browse to select it from your device.
Optionally, pick your desired AAC bitrate (for example, 128, 192, or 256 kbps).
Click Convert and wait for the progress bar to finish.
Download the M4A file to your device. The conversion runs locally; nothing is uploaded.

Why convert FLAC to M4A?

FLAC is a popular lossless format for music collectors, audiophiles, and anyone archiving audio at full quality. Many download stores (Bandcamp, Beatport, HDtracks), rippers, and recording tools export FLAC. However, FLAC is not natively supported on iPhones, iPads, many car stereos, or in most streaming apps. M4A (AAC) is the default for Apple devices and a safe choice for most modern phones and music players.

M4A files use the AAC codec, which is lossy but efficient. At 192 kbps, a 4-minute stereo song in M4A is usually 5.5–6 MB, compared to 25–30 MB for the same FLAC. That is a reduction of about 80%. The sound quality at 192 kbps AAC is transparent for most listeners and almost always good enough for everyday use, streaming, or portable listening.

If you want to save space on your phone, upload tracks to a music service, or email audio, converting FLAC to M4A is a practical option. AAC in M4A is widely compatible and plays in iTunes, Apple Music, iOS, Android, and most smart speakers out of the box.

You should not convert to M4A if you need to preserve every bit of the original audio (for example, for archiving, editing, or future conversion). The process is lossy — once converted, the fine details discarded cannot be recovered. For music libraries you want to keep long-term, keep the FLAC as your original.

FLAC vs M4A: what's the difference?

Property	FLAC	M4A (AAC)
Extension	.flac	.m4a
Compression	Lossless	Lossy (AAC)
Typical size (4 min, stereo)	25–30 MB	5–6 MB (192 kbps)
Quality	Bit-for-bit original	Audibly transparent at 192+ kbps
Device support	Most PCs, Android, VLC; not iPhone by default	iPhone, iPad, Mac, Android, Windows, most players
Tagging support	Excellent (Vorbis tags)	Good (iTunes tags, artwork)

FLAC is a lossless audio format that preserves the original recording with no quality loss but results in large files. M4A (using AAC) is a compressed, lossy format that trades a small amount of quality for much smaller file sizes and broad device support.

Does converting FLAC to M4A reduce quality?

Yes. FLAC is lossless: it keeps every detail of the original recording. M4A (AAC) compresses audio by removing details most people cannot hear. Our converter lets you pick the AAC bitrate from 96 to 320 kbps. 192 kbps is the default — a good balance for most music. Lower bitrates save more space but may sound dull or watery, especially on headphones or speakers with good range.

If you choose a high bitrate (256 or 320 kbps), the M4A will be bigger but closer to the FLAC in quality. For podcasts and spoken word, 96–128 kbps is fine. For classical, jazz, or music with a lot of dynamic range, use 192 kbps or higher. Remember, converting from FLAC to M4A is one-way: you cannot get back the lost quality by converting the M4A back to FLAC later.

Are there built-in ways to convert FLAC to M4A?

Windows and macOS do not provide a direct FLAC to M4A conversion in their built-in tools. iTunes (Music app on Mac) can encode to M4A (AAC) but does not open FLAC files natively. You would first need to convert FLAC to WAV using a tool like VLC, then import into iTunes to convert to AAC, which is awkward and slow.

VLC Media Player can play FLAC and convert it to MP3 or WAV, but does not export directly to M4A/AAC on all platforms. Audacity can open FLAC, but exporting as M4A/AAC requires installing the optional FFmpeg library. On iOS and Android, there are some apps for audio conversion, but most require payment or upload your audio to a server.

Videozify runs entirely in your browser, keeps your audio local, and avoids multi-step conversions. No account or install required.
