Convert 3GP to WebM
Updated Jul 2026
3GP is the compressed video format older mobile phones used to save space on slow networks, while WebM is a modern format built for the web and plays natively in browsers. To convert 3GP to WebM, open the file in a converter and export it as WebM. Doing this on your own computer means the video never has to travel to a stranger's server.

How to convert 3GP to WebM
- Open Morphjet and drag in the 3GP video, or a whole folder of old clips at once.
- Choose WebM as the output format.
- Convert. The WebM file is written right next to the original, and nothing leaves your machine.
3GP vs WebM: what actually changes
| 3GP | WebM | |
|---|---|---|
| Opens in web browsers | Rarely, most browsers dropped support | Yes, plays natively in modern browsers |
| File size | Already small, from heavy compression | Similar size, usually better quality per byte |
| Video quality | Low resolution, built for old mobile networks | Can preserve the source, but can't improve on it |
| Audio quality | Compressed for phone calls, often tinny | Can carry clearer audio if the source allows it |
| Plays on current phones and computers | Inconsistent, many devices dropped support | Broad, works across phones, computers, and browsers |
When to convert, and when not to
Convert 3GP to WebM when you want to watch old phone videos again, post them online, or embed them on a website, since most current browsers and devices no longer open 3GP directly.
Keep the original 3GP file if it's the only copy of an old memory you're not ready to touch yet, since re-encoding a video that was already low quality won't add back detail that was never there.
Why not just use an online converter?
Old 3GP clips are often personal, home videos of kids or family events you'd rather not hand to a stranger's server. Many online converters require you to upload the file, wait for it to process, and download it back, which means a copy sits on someone else's system in the meantime. Converting on your own computer keeps the video exactly where it already is.
Questions
Will converting 3GP to WebM make the video look better?
No. WebM can hold more detail than 3GP, but the conversion can't add back quality the original 3GP never had. The video will look the same, just in a format that plays in more places.
Does converting to WebM lose quality compared to the original?
There's a small re-encoding step, but if you keep a similar quality setting, the difference isn't noticeable next to the original's own low resolution and compression.
Why won't my phone or browser play a 3GP file anymore?
3GP was built for early mobile networks and phones from the 2000s and 2010s. Most current phones, browsers, and video apps dropped support for it since it's rarely used for anything new.
Can I convert a batch of old 3GP videos at once?
Yes. Morphjet can take a whole folder of old clips and convert them to WebM in one pass, so you don't have to do them one at a time.
Can I convert 3GP to WebM without uploading it anywhere?
Yes. Morphjet converts on your own computer, so the video never has to leave your machine or pass through anyone else's server.
Morphjet converts 3GP, WebM, and 1,800+ other formats, all on your machine. Launching this July.
