How to convert WebM to TS

  1. Add your WebM videos

    Drop WebM 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. TS 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 TS, or download everything as one ZIP if you converted several files.

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

WebM to TS: what to expect

WebM does not play on many phones, TVs or in most video editors. A transport stream is what broadcast and streaming toolchains ingest. WebM is at home in royalty-free video on websites; TS is the usual choice for broadcast recordings and camcorder footage (MTS, M2TS).

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.

The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. A video over 500 MB cannot be kept at full quality in browser memory; choosing a lower resolution or quality under Options lets it fit.

WebM vs TS

WEBM

WebM video

WebM is an open, royalty-free video format built for the web. It is a restricted form of Matroska holding VP8, VP9 or AV1 video. Browsers play it; iPhones, TVs and video editors often do not.

Opens in Chrome, Firefox, Edge and recent Safari; few TVs and editors

WebM converter
TS

MPEG transport stream

A transport stream is how digital TV is broadcast. The same format, under the MTS or M2TS extension, is what AVCHD camcorders record. It is built to survive transmission errors, not for convenient sharing.

Opens in VLC and TV software; not phones or browsers directly

Questions

Are my videos uploaded anywhere?

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

Does converting WebM to TS reduce quality?

It depends on what is inside the WebM. When its video and audio are already in a form TS 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 WebM 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 WebM to TS 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 WebM file, press Convert and save the TS. There is nothing to install.

Is there a file size limit?

Yes. Files up to 2 GB are accepted, and a video over 500 MB needs a lower resolution or quality chosen under Options so the result fits in memory. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
