Why convert to WEBM

Made for playing in a browser

WEBM is the format Chrome, Firefox and Opera read for HTML5 video playback, so a WEBM file plays on a web page without a plug-in and without a download.

Any video goes in

MP4, MOV, AVI, MKV, WMV, FLV and the rest all convert to WEBM the same way. The format is read from the file itself, and you can add several videos at once.

Nothing to install

Conversion runs on our servers over an encrypted connection. There is no software to download and no account needed to use it.

What WEBM is good for

What is WEBM and why would you want to convert your videos to WEBM? There are several good reasons. First, WEBM is a completely royalty-free video format, which means that many people can work with it and introduce improvements. Second, WEBM is supported by many browsers such as Opera, Google Chrome, and Mozilla Firefox for seamless video playback.

It is widely used in many HTML5 video players, for example by Skype, Nintendo, Logitech, and more. If you want to use your video online, for streaming or better compatibility, consider converting it to WEBM.

You can also paste a link instead of uploading, or pull the file in from cloud storage.

The video settings

The video codec select decides how the picture is stored inside the WEBM file. VP9 is the usual answer, VP8 is the older codec that even ancient browser versions read, and AV1 reaches a similar picture in a smaller file but needs a recent player. Copy carries the existing video stream over untouched and only rewraps it, which is the fastest route when the video is already VP8, VP9 or AV1.

Frame rate and screen size are there for a target device that needs a particular number, and deinterlacing cleans up footage from an older camera or a TV recording.

The bitrate method decides how quality is controlled. CRF asks for a constant quality and lets the size follow, on a scale where a lower number means better quality and a bigger file. Constant and variable bitrate let you name the figure in kbps instead.

Anything you do not touch is not sent at all, so the engine keeps its own defaults for it.

The audio settings

WEBM carries Vorbis or Opus sound, and the audio codec select offers both plus Copy, which keeps the existing track as it is. Bitrate, sample rate up to 48000 Hz, and stereo or mono are separate selects beside it.

There is also a switch that removes the audio completely, which is what you want for a silent background clip or before you put a new sound track on the video.

Free to use, and private by default

Converting a video to WEBM is free and needs no account. Every upload and download runs over an encrypted connection, so your footage cannot be read on the way.

Processing is fully automated: nobody watches your videos and they are never used to train AI models. You keep the copyright and the ownership of both the video you upload and the one you get back.

The servers that do the work are in Europe.

Convert to WEBM online for free

1

Upload

Upload your video. You can drag and drop a file, browse your hard drive or phone, paste a link to an online video, or select a file from cloud storage like Dropbox or Google Drive. You can also upload several videos at once.

2

Video settings

The video settings are completely optional. You can use them to adjust the quality of your converted videos by changing the frame rate, screen size (in pixels), and video bitrate. You can also mute your videos by disabling the audio track. This is useful if you want your video to loop on your website without disturbing your visitors or customers.

All that is left to do now is click "Start" for Video2Edit to begin. It will convert your files and provide the WEBM videos for download on the next page. You can download each video individually or, if you converted more than one, download them all together in a ZIP archive. Just click the relevant button and start using your new WEBM video.

Questions about converting to WEBM

Which formats can I convert to WEBM?

Any video file the converter reads, which covers MP4, MOV, AVI, MKV, WMV, FLV, MPG, 3GP and more. You do not have to say what you are uploading: the format is read from the file.

Where does a WEBM file play?

In a browser, which is what the format was made for: Chrome, Firefox and Opera play it directly in an HTML5 video player. Older desktop players and some TV sets and phones do not read it, so pick MP4 instead when the file has to open anywhere at all.

Which video codec should I pick?

VP9 if you have no reason to choose otherwise. VP8 if very old browser versions have to play the file. AV1 if a smaller file matters more than playing on older devices. Copy if the video stream is already VP8, VP9 or AV1 and you only want it wrapped in WEBM, which is also the quickest of the four.

Can I mute the video?

Yes. One switch in the settings drops the sound track completely, which is what you want for a clip that loops on a web page. The audio codec, bitrate, sample rate and stereo or mono are separate selects if you would rather keep the sound and change it.

Can I convert several videos at once?

Yes. Add as many as you like and each one is converted separately with the same settings, then returned as its own WEBM.

Does it cost anything?

No. Converting to WEBM here is free and does not require an account. A paid plan raises the upload limit and how many files you can process at once.
