The video engine (about 30 MB) is downloaded once and then cached. Your videos never leave your device; long or HD videos can take a few minutes.
Drop the FLV video onto the page, paste it, or click to choose. It is read directly from your device.
Everything is set up for AVI. Adjust the size or other options if you like — the defaults suit most videos.
The conversion runs in your browser. When it is finished, save the AVI file to your device.
Flash Video
The old Flash video format
FLV was the video format of Adobe Flash and early YouTube. Since Flash was discontinued, almost nothing plays it any more.
Audio Video Interleave
The classic Windows video format
AVI (Audio Video Interleave) was introduced by Microsoft in 1992 and was the standard for DivX and Xvid videos for many years.
Family clips, screen recordings and work videos never leave your device. There is no server copy to leak or delete.
No account, no watermark, no daily limits and no waiting queue. Only your device's memory sets the limit.
When the streams already fit the target format they are copied without re-encoding: done in seconds with zero quality loss.
Add your FLV file to the tool above. AVI is already selected, so processing starts with the right settings. When it is done, click Download.
The video is re-encoded as MPEG-4 (Xvid) with MP3 audio at a high quality setting. Files are larger than modern formats, but play on old devices.
No. The FLV to AVI conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your video never leaves your device.
If the streams can be copied, a few seconds. If the video has to be re-encoded, roughly one to three minutes per minute of 720p video on a computer, and longer on phones.
