About WAV to FLAC conversion
WAV is a common uncompressed audio format from recorders and DAWs. Files are large because samples are stored as PCM. FLAC is a lossless compressed format: it keeps the same audio quality while using less disk space, which is useful for archives and hi-fi libraries.
This page converts WAV to FLAC in your browser. You add a WAV, run Convert to FLAC, then download or save the result to Your Library without uploading the file to Sound Booster servers for the conversion step.
Use WAV to FLAC when you want smaller lossless backups, when a library tool prefers FLAC, or when you need to store many long recordings without the bulk of raw WAV.
Very long or high-sample-rate WAV files need enough memory. If conversion fails, try a shorter clip or Chrome/Edge, and keep the tab open until progress reaches 100%.
How to convert WAV to FLAC
Converting WAV to FLAC on Sound Booster stays local: add the WAV, encode to FLAC, download when progress finishes.
Output is fixed to FLAC. The first run in a session may load the browser encoder before work starts.

WAV and FLAC formats
What is a WAV file?
WAV is a common uncompressed container, usually holding PCM samples from recorders and DAWs. Editors open it easily, but file size grows quickly with length and sample rate — long sessions can fill a drive faster than a compressed lossless format would.
What is a FLAC file?
FLAC is a lossless compressed format. It preserves the same audio quality as the source WAV while typically using less disk space. That makes FLAC a practical choice for archives, backups, and hi-fi libraries when you still want bit-perfect storage.
What people use it for
Smaller archives
Store lossless copies of sessions without the full size of WAV folders.
Hi-fi libraries
Keep collection tracks lossless in a format many players support.
After editing
Export WAV from a DAW, then compress to FLAC for long-term storage.
Backup drives
Fit more lossless audio on the same disk than with raw WAV.
Frequently asked questions
Does WAV to FLAC restore lost quality?
No. Conversion expands the file to PCM, but detail already removed by MP3 encoding cannot be recovered. WAV is still better for editing and further processing.
Do my files leave this device?
No. Decoding and WAV encoding are designed to run locally in the browser for this tool.
Is it free?
Yes on this page, without a mandatory account.
Why is the WAV so large?
Uncompressed PCM needs more disk space than MP3. That is normal and expected for editor-friendly files.
Why did conversion fail?
Try Chrome or Edge, a shorter file, and keep the tab open until progress reaches 100%.
