Frequently Asked Questions

Will converting to FLV reduce quality?

When the source already uses a codec FLV supports, we copy it without re-encoding, so nothing is lost. Otherwise we re-encode at standard quality.

Can I convert a YouTube video to FLV?

No. The converter only works with files you upload from your device.

Are my files private?

Yes. All transfers are encrypted, and your files are deleted from our servers automatically one hour after processing. We never share them.

How to open a FLV file?

Desktop apps like VLC or MPC‑HC open FLV seamlessly. If you encounter a Spark‑encoded clip, convert using FFmpeg: `ffmpeg ‑i input.flv ‑c:v h264 output.mp4`. Web players no longer stream FLV, so upload sites recommend remuxing to MP4 or WebM.

What is a FLV file?

Flash Video (FLV) is a container that encapsulates Sorenson Spark, VP6, or H.264 video together with MP3/AAC audio and on‑screen data events for ActionScript. It became the backbone of early YouTube and news portals because the small header footprint yields quick progressive playback. Macromedia introduced FLV in 2002 with Flash Player 6, offering the first ubiquitous plug‑in‑based video experience on the Web. After Adobe’s acquisition, FLV evolved to support H.264 in 2007 but began losing ground once HTML5 gained traction. By the end of 2020, Adobe disabled Flash, and most CDNs convert FLV archives to MP4 or HLS.
