Convert FLV to FLAC when you are archiving music without losing a single bit. FLV is the old Flash Video format — nearly extinct on the modern web, but decades of archived streams and legacy players still use it; FLAC is lossless audio compression — every bit of the original preserved at roughly half the size of WAV, the archivist’s music format. Upload your FLV, hit convert, download the FLAC — free, no sign-up, no watermark.
The FLV to FLAC Converter is one instrument in the widest bench in the fleet: on UniversalConverter, a file can arrive by link or upload and leave as video, audio, image or document — the universal bar and the full matrix are here precisely so no job needs a second site.

This page converts specifically to FLAC — for another output format use the general converter.
A short ad is shown before processing — it keeps this tool free. No sign-up, no watermark.
Only the soundtrack is kept: the picture is dropped and the audio is written as a standalone FLAC file. File sizes stay in the same ballpark — both formats compress with loss, so the FLAC lands within roughly a third of the FLV's size at these quality settings. People make this exact swap when you are archiving music without losing a single bit.

Why people pick this over other converters
No account, ever. Most big converter sites push sign-ups and paid tiers for basic jobs. Here the tool just works.
No watermarks and no job counters on standard tools — fair-use rate limits keep things fast for everyone — and a generous 200 MB upload limit.
Private by design: your file is processed in a temporary folder and deleted the moment your download finishes. Nothing is stored or shared.
Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 396 other tools when you need them.
FAQ
Will converting FLV to FLAC lose quality?
The FLAC will be a bit-perfect copy of what is in your FLV — but FLV already threw detail away when it was created, and no conversion can invent it back. Expect a much bigger file with exactly the same quality, which is worth it only for editing or archiving.
When should I convert FLV to FLAC?
Convert when you are archiving music without losing a single bit. If your FLV already opens where you need it, converting buys nothing — this swap earns its keep the moment a device, app or upload form refuses FLV but accepts FLAC.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
