FLAC Converter

Convert FLAC to Any Audio Format

FLAC — the Free Lossless Audio Codec — stores a bit-perfect copy of your music in roughly 40–60% of the space an uncompressed WAV would take, with no loss in quality. The catch is reach: not every phone, car stereo, or media player decodes FLAC, and Apple's Music app and iTunes still won't import it. This converter turns a FLAC file into MP3, WAV, OGG, M4A, AAC, or Opus — files are processed on our servers, then download straight to your device so the audio plays wherever you need it. Most people are here for FLAC to MP3 — small, universal, and the default output below — but every common target is one dropdown away.

How to Convert FLAC to MP3 (or Any Format)

1. Upload Your FLAC File: Drag and drop your file onto the page or click "Add Files". You can queue several FLAC files at once and convert them in a single batch.
2. Pick the Audio File Extension: The output dropdown defaults to MP3. Switch it to WAV, OGG, M4A, AAC, OPUS, or any other listed format depending on where you want to play the audio.
3. Set Quality (Optional): Open Advanced Options to choose a Quality Preset (Highest to Lowest), or set a Constant Bitrate or Variable Bitrate yourself — 192–320 kbps for music, 96–128 kbps for spoken-word. You can also override the Audio Sample Rate and Audio Channel (Original, Mono, or Stereo), target a Specific file size, or use Trim to keep only part of a track.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Popular FLAC Conversions

• FLAC to MP3 — the portable, universal default. MP3 plays on virtually every device built in the last two decades and lands at roughly 5–10× smaller than the FLAC source.
• FLAC to WAV — decode to uncompressed PCM for editing in a DAW (Audacity, Audition, Logic, Pro Tools) where you want zero decode overhead.
• FLAC to OGG — open, royalty-free Vorbis. A good fit for games, Godot/Unity projects, and the Spotify-style streaming stack.
• FLAC to M4A — AAC inside an MP4 container, the format iPhones, iPads, and CarPlay handle natively.
• FLAC to AAC — efficient lossy audio for Apple devices, YouTube, and broadcast workflows.
• FLAC to Opus — the best quality-per-kilobyte at low bitrates, ideal when file size matters most.

Need the reverse? Use the audio to FLAC converter to archive a WAV, M4A, or other source as lossless FLAC, or compress FLAC to shrink an existing FLAC without leaving the format.

Which Format Should You Convert FLAC To?

A Note on Quality: Lossy Targets Are Permanent

FLAC is lossless, so converting one FLAC to another, or to WAV, throws nothing away. But MP3, AAC, OGG, and Opus are lossy — they permanently discard audio data to hit a smaller size, and you cannot reverse that. A FLAC re-encoded to 320 kbps MP3 is excellent for listening, but it is no longer a master, and converting that MP3 back to FLAC will not restore what was removed.

The practical rule: keep your FLAC originals. Treat the lossy file as a disposable copy for your phone, your car, or sharing, and re-export from the FLAC whenever you need a different target. That way every export starts from the full-quality source instead of compounding loss generation after generation.

Choosing a Bitrate and Sample Rate

Bitrate controls the size–quality trade-off of a lossy output. For music, 256–320 kbps is transparent for most listeners on typical gear; 192 kbps is a sensible "small but good" middle ground; 96–128 kbps suits podcasts, audiobooks, and voice notes where speech clarity matters more than fidelity. Variable Bitrate (VBR) generally gives better quality at a given average size than a fixed Constant Bitrate, because it spends bits on complex passages and saves them on quiet ones — pick CBR only when a target device or platform requires a fixed rate.

Sample rate is how many times per second the audio was measured. CD-quality audio is 44.1 kHz, and most music lives there; 48 kHz is standard for anything tied to video. Don't upsample — converting a 44.1 kHz FLAC to a higher rate adds no real detail and only inflates the file. Leaving Audio Sample Rate on "Original" keeps the source rate, which is the right choice for nearly everyone.

Frequently Asked Questions

What does FLAC stand for, and is it really lossless?

FLAC is the Free Lossless Audio Codec, developed under the Xiph.Org Foundation. "Lossless" means the compressed file decodes back to audio that is bit-for-bit identical to the original — nothing is discarded, unlike MP3 or AAC. It is also royalty-free and patent-unencumbered, which is why it became the standard for music archival and lossless download stores.

Why convert FLAC to MP3 if MP3 loses quality?

Reach and size. FLAC files are large and aren't supported everywhere — many car stereos, older players, and Apple's Music app can't open them. MP3 plays on practically any device and is roughly 5–10× smaller. At 256–320 kbps, most listeners can't distinguish MP3 from the original on typical equipment, so it's an excellent format for portable, everyday listening — as long as you keep the FLAC as your archive copy.

Will I lose quality converting FLAC to WAV?

No. Both FLAC and WAV are lossless, so a FLAC-to-WAV conversion decodes the audio with zero loss — the WAV is bit-identical to what the FLAC stored. The only difference is that WAV is uncompressed, so the file is larger (CD audio runs about 10 MB per minute) and WAV has no standard scheme for tags or cover art. Use WAV when an editor or DAW prefers raw PCM, and FLAC when you want the same fidelity in less space with metadata intact.

Can my iPhone play FLAC, or should I convert it?

Apple's Music app and iTunes still won't import FLAC. iOS can play a FLAC file through the Files app since iOS 11, but if you want tracks in your Apple Music library, on an Apple Watch, or through CarPlay, convert to M4A (AAC) or to ALAC. AAC at 256 kbps is the format Apple Music itself uses, so it's a natural fit for the ecosystem.

What bitrate should I pick when converting FLAC to a lossy format?

For music, 256–320 kbps is transparent for most people and is the safe default. 192 kbps is a good compromise when you want smaller files; 96–128 kbps is fine for podcasts, audiobooks, and voice. Variable Bitrate usually beats Constant Bitrate at the same average size. Whatever you choose, you're encoding from a lossless FLAC source, so the result is as good as that bitrate allows — there's no extra generation loss the way there would be re-encoding an existing MP3.

How much smaller is FLAC than WAV, and MP3 than FLAC?

A FLAC file is typically 40–60% the size of the same audio as uncompressed WAV — so a 50 MB WAV often lands around 20–30 MB as FLAC, with identical quality. Convert that FLAC to a 320 kbps MP3 and it shrinks again to roughly 10% of the uncompressed size. As an illustrative example: a 4-minute CD-quality track runs about 42 MB as uncompressed WAV (1,411 kbps × 240 s ÷ 8), compresses to roughly 17–25 MB as FLAC, and encodes to around 9–10 MB as a 320 kbps MP3 — the exact figures vary with how dense and complex the music is.

Does converting FLAC keep the artist, album, and cover art?

When converting to a format that supports tags — MP3, M4A/AAC, and OGG all do — the common Vorbis-comment fields FLAC carries (title, artist, album, track number) map across, and embedded cover art is preserved where the target format allows it. WAV is the exception: its container has no standard tagging scheme, so a FLAC-to-WAV conversion gives you the audio but not a reliably tagged file, which is one more reason to keep FLAC as your archival master.
