How to convert MOV to FLV

  1. Add your MOV videos

    Drop MOV (QuickTime) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. FLV is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.

  3. Download

    Save the FLV, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The MOV to FLV converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

MOV to FLV: what to expect

MOV does not play reliably on Windows, Android, smart TVs or in many upload forms. FLV is still used by some live-streaming and recording tools. MOV is at home in recording and editing on Apple devices; FLV is the usual choice for nothing new; it survives in old downloads and stream recordings.

The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.

This pair uses the compatibility engine, ffmpeg built for the browser, because FLV cannot be written by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.

MOV vs FLV

MOV

QuickTime video

MOV is Apple's QuickTime container and what iPhones and Macs record. MP4 was based on it, so the two are close relatives and often hold exactly the same video and audio streams inside.

Opens in Apple devices and video editors; Windows and Android are hit and miss

MOV converter
FLV

Flash video

FLV was the format behind web video in the Flash era. Flash Player was retired at the end of 2020, so FLV files no longer play in any browser.

Opens in VLC and little else since Flash Player was retired in 2020

Questions

Are my videos uploaded anywhere?

No. The MOV to FLV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting MOV to FLV reduce quality?

It depends on what is inside the MOV. When its video and audio are already in a form FLV can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.

Can I convert several MOV files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert MOV to FLV on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MOV file, press Convert and save the FLV. There is nothing to install.

Is there a file size limit?

Yes. MOV to FLV runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
