About converting WAV to FLAC
Use this free WAV to FLAC converter to change WAV audios into FLAC without uploading anything, installing software or signing up. WAV stores uncompressed PCM samples at full fidelity, making it the standard working format for recording, mastering and audio editing. FLAC compresses audio losslessly to roughly half size, so it is bit-for-bit identical to the source on decode - the archivist's choice for music libraries.
The WAV-to-FLAC conversion is the usual trade between fidelity and footprint: lossless formats preserve every sample for editing and archiving, while lossy ones fit far more music onto a device.
Because every conversion runs on your own device through WebAssembly builds of the same open-source engines desktop tools use, there is no upload queue, no file-size cap imposed by a server, and no copy of your WAV sitting in someone else's storage afterwards. That matters most for anything you would hesitate to hand to a third party - identity documents, contracts, medical scans, unreleased work, client material. It also means the converter keeps working with no network connection at all once the page has loaded.
WAV to FLAC is one of many routes available here. If a direct path between two formats does not exist, the converter automatically chains several conversions together to reach the one you asked for, so you can get from almost any input to almost any output in a single step.

Frequently asked questions
- Is this WAV to FLAC converter free?
- Yes, completely. There is no charge, no account, no watermark on the output and no daily conversion limit.
- Are my files uploaded to a server?
- No. The conversion runs in your browser using WebAssembly, so your WAV file never leaves your device and nothing is stored anywhere after you close the tab.
- Is there a file size limit for WAV to FLAC conversion?
- There is no server-imposed limit, because there is no server involved. The practical ceiling is your own device's available memory, so very large files convert faster on a desktop than on a phone.
- Does converting WAV to FLAC reduce quality?
- It depends on the target format. FLAC output is produced at high quality settings, but converting into a lossy format always discards some data by design, and re-encoding an already-lossy file compounds that. Convert from the highest-quality source you have rather than from a previously converted copy.
