How to convert FLV to AVI
Upload your FLV file
Drag and drop a FLV file to turn into AVI, or click to browse. Anything under 1GB, and nothing is installed.
Confirm AVI as the output
AVI is already selected, so there is nothing to configure. Switch to another format in the panel if FLV needs to go somewhere else.
Convert and download
We convert the FLV on our servers, usually in under a minute. Create a free account to download the AVI, or keep editing it in REQO.
Why convert FLV to AVI?
FLV was built for the Flash player, which browsers dropped for good at the end of 2020. Any FLV you still have is an archive file that needs converting before it can be watched or edited.
The practical problem: No browser has played Flash video since 2020, so FLV is effectively unplayable on the web. Editors and phones will not open it. The old codecs inside look soft next to a modern H.264 encode.
AVI solves that. Widely readable by desktop players from the same era.

FLV to AVI questions
Is the FLV to AVI converter free?
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the AVI itself beyond the free-plan badge.
Do I need to install any software?
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where FLV plays: Desktop players only, with effort. Where the AVI you get back plays: Desktop players with the right codec pack.
Does converting FLV to AVI reduce the quality?
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the FLV on normal viewing. What changes is the container and the codec. AVI holds: DivX, Xvid, MJPEG and other legacy codecs. Converting the same file back and forth repeatedly will eventually show, so keep your original.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. FLV: Moderate, heavily dated. AVI coming back: Very large for the quality. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
