Free converter
Anyfile converts an F4V video to a WebM video for free, right in your browser: the file is never uploaded.
Files are converted in your browser and never uploaded. By using Anyfile you agree to the Terms of Use.
| Picture | Copied as it is when it fits; otherwise re-encoded by your browser at the same size and frame rate |
|---|---|
| Sound | The first sound track is kept |
| Subtitles and chapters | Not carried over yet |
| File size | Usually smaller: WEBM compresses more tightly than F4V |
When to use WEBM: Video embedded in web pages, and screen recordings made in the browser.
Open the file in the video editor to choose before downloading:

About WEBM filesEverything that converts to WEBM
Need to change it first? Open the video editor
Drop your F4V file on this page, or choose it. Anyfile converts it on your device in a moment and the WEBM downloads straight away. To change it first, open it in the video editor.
No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.
WEBM is a compressed format, and Anyfile saves at high quality, so the difference is very hard to notice.
Yes. Drop them together and you get one ZIP with every WEBM inside.
