About the WAV to FLAC conversion
A practical look at what happens during this conversion, what to expect from the output, and the trade-offs involved.
FLAC uses lossless compression, but conversion can still change sample representation or metadata. Check output properties before treating it as an archival replacement.
This page processes the first audio stream, omits embedded artwork and does not provide tag editing or compression-level controls. File size depends on the recording.
Watch out
Retain the WAV master
Do not assume every WAV sample format is preserved identically by the selected encoding defaults.
Pro tip
Inspect audio properties
Check sample rate, channels, duration and playback after conversion.
When not to convert
Keep WAV for a WAV-based workflow
If your editor already uses the WAV successfully, conversion may not be necessary.
When to convert WAV to FLAC
Use this conversion when your destination needs FLAC and you have a WAV source. Keep the original so you can compare the result or try another supported format.
Audio is decoded and re-encoded using format-specific defaults. Sample format and some metadata may change. Embedded cover art is omitted. A lossless destination cannot recover detail lost in the source.

How to Convert WAV to FLAC
Follow these simple steps to convert your file in seconds.
Choose a WAV file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to FLAC
Audio is decoded and re-encoded using format-specific defaults. Sample format and some metadata may change. Embedded cover art is omitted. A lossless destination cannot recover detail lost in the source.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting WAV to FLAC
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
WAV Audio has a known limitation: very large file sizes (approximately 10 MB per minute for CD quality). FLAC Audio addresses this with a key advantage: completely lossless compression preserving bit-perfect audio quality. Converting from WAV to FLAC is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
WAV Audio is most commonly used for professional audio recording and production, while FLAC Audio is the standard for audiophile music collections and high-fidelity playback. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where WAV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the FLAC output
FLAC Audio has its own limitation worth understanding before you commit: still significantly larger than lossy formats like MP3 or AAC. After the conversion completes, open the FLAC file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Understand lossy vs. lossless before converting
Converting from a lossy format like MP3 to a lossless format like FLAC or WAV does not restore lost audio data — it only changes the container. If you need true lossless quality, always start from an uncompressed or lossless source. Converting lossless to lossy, however, is a valid way to reduce file size for streaming or mobile playback.
Understanding WAV and FLAC Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
WAV Audio
audio/wavWAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM, storing raw PCM audio data in a RIFF container. It preserves the full quality of the original audio recording with no compression artifacts. WAV files are commonly used in professional audio production where lossless quality is essential.
Advantages
- Completely lossless with no compression artifacts whatsoever
- Universal support in all audio editing software and operating systems
- Simple format that is fast to read, write, and process
Limitations
- Very large file sizes (approximately 10 MB per minute for CD quality)
- Metadata support and preservation vary across audio software
- Impractical for streaming or portable device storage due to size
Common Uses
- Professional audio recording and production
- Master audio archival and studio workflows
- Audio editing and processing intermediate format
Target Format
FLAC Audio
audio/flacFLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format that typically reduces file sizes by 40-60% compared to uncompressed WAV. It preserves the complete original audio data bit-for-bit, allowing perfect reconstruction of the source. FLAC supports high-resolution audio up to 32-bit depth and 655,350 Hz sample rate with embedded metadata and album art.
Advantages
- Completely lossless compression preserving bit-perfect audio quality
- Open-source and royalty-free with broad software and hardware support
- Typically 40-60% smaller than equivalent WAV files
Limitations
- Still significantly larger than lossy formats like MP3 or AAC
- Not supported by all portable devices and car audio systems
- Encoding and decoding requires more CPU resources than uncompressed formats
Common Uses
- Audiophile music collections and high-fidelity playback
- Lossless music archival and library preservation
- Source format for transcoding to lossy formats for distribution
