How to convert WAV to FLAC
- Drop in your WAV audio stems, mixdown masters, or sample collections.
- Leave channel and sample rate settings on Keep original to preserve pure bit-exact fidelity.
- Convert to FLAC and download your compressed lossless tracks or a complete ZIP package.
Archiving studio multitracks and session stems
Uncompressed multitrack studio sessions quickly consume terabytes of hard drive space across active production drives. Converting completed album projects and stems to FLAC reduces their footprint by 40% to 60% while maintaining every sample of digital audio data.
Because FLAC is a mathematically lossless format, decompressing the file at any future date produces the identical waveform as the original studio master. Using compression level 5 ensures optimal file shrinking without burdening your computer processor during batch exports.
Calculating storage savings for audio creators
Raw CD-quality stereo WAV audio demands approximately 10 MB per minute of running time, making large stem folders cumbersome to store and slow to transfer. FLAC reduces that data rate down to roughly 4 to 6 MB per minute, saving substantial backup drive space across large session libraries.
Tracks containing acoustic instruments, solo vocals, and dynamic pauses achieve the highest compression ratios. Dense electronic productions with wall-to-wall noise or heavy saturation compress slightly less, but still provide valuable space savings over raw PCM.
Retaining pristine sample fidelity
To ensure your FLAC files remain bit-exact replicas of your studio WAV recordings, keep Channels and Sample rate on Keep original. Any adjustment to those parameters under More settings forces digital resampling, which permanently alters the underlying audio data.
The conversion takes place inside your browser tab using WebAssembly, ensuring confidential studio masters and unreleased tracks remain strictly on your physical machine. Use Continue with to pass files to other studio utilities.
Questions
Will my DAW be able to open these FLAC files?
Most modern DAWs, including Reaper, FL Studio, Logic Pro, and Ableton Live, support direct FLAC importing on their timelines.
Is any sonic nuance lost when moving from WAV to FLAC?
None at all. FLAC is completely lossless; the audio samples decoded from FLAC are mathematically identical to the source WAV.
Can I batch compress an entire album of WAV stems?
Yes. Load all your project stems into the queue; each file compresses sequentially and can be downloaded as a single ZIP.
How does FLAC compare in file size to MP3?
While FLAC is 40% to 60% smaller than uncompressed WAV, lossy MP3 at 192 kbps is roughly 85% smaller; FLAC prioritizes perfect fidelity over minimal size.
