How to convert 3GP to WebM

  1. Add your 3GP videos

    Drop 3GP 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. WebM 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 WebM, or download everything as one ZIP if you converted several files.

3GP to WebM: what to expect

3GP video is low resolution and does not open in many desktop apps. WebM is royalty-free and well suited to embedding in web pages. 3GP is at home in video from older mobile phones; WebM is the usual choice for royalty-free video on websites.

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.

Questions

Are my videos uploaded anywhere?

No. The 3GP to WebM conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting 3GP to WebM reduce quality?

It depends on what is inside the 3GP. When its video and audio are already in a form WebM 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 3GP 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 3GP to WebM 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 3GP file, press Convert and save the WebM. 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.
