How to use this tool

  1. Choose files or drag them into the workspace. Matching inputs get the output format shown on this page.
  2. Check the output format and image quality for each file. Existing files in your queue keep their settings.
  3. Start the conversion, then download individual results or the completed batch. Your original files are unchanged.

Quality and format notes

FLV is the Flash video container from the 2000s web, still sitting in old download folders. Its audio is typically MP3 or AAC; conversion produces a clean standalone MP3.

FLV files without an audio track — silent screen recordings — have nothing to extract and fail clearly. Corrupt downloads from long-dead servers may not decode.

Frequently asked questions

Why do I still have FLV files?

The 2000s web ran on Flash, and old download folders preserve it. Convert the audio you care about; the rest can finally go.

What audio is inside an FLV?

Usually MP3 or AAC. Either decodes here and re-encodes to a fresh MP3 at your chosen bitrate.

Can I convert several FLV files at once?

Yes. Queue the whole batch; results download individually or as a ZIP, all processed on your device.
