Convert WebP to 3GP
Turn your WebP into a 3GP that plays smoothly and takes a fraction of the space. 3GP is the usual choice for video recorded on older mobile phones. One thing to know first: anything see-through in the WebP comes out on a solid background, white unless you choose another colour. Your file never leaves your computer.

How to convert WebP to 3GP
- 1 Drop your WebP .webp file onto the page, or click to browse for it.
- 2 Pick how smooth and how sharp you want it. The defaults suit a short looping clip.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the 3GP, or add more files and do the whole set in one go.
Why convert WebP to 3GP
- The same animation as a 3GP is routinely a tenth of the size, plays smoothly and stops stuttering on a slow connection.
- You are sending this somewhere that will not keep a transparent background anyway, so putting it on a solid colour costs you nothing.
- Very small files suited to constrained networks.
- Structurally MP4, so conversion is straightforward.
- MMS attachments and low bandwidth clips.

| Transparency | Yes | No |
| Animation | Yes | No |
| Typical file size | Depends on mode | Smaller |
| Browser support | Every browser | No browser support |
| Introduced | 2010 | 2001 |
| Developed by | 3GPP |
Quality and what changes
3GP stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- Anything see-through comes out on a solid background, white unless you choose another colour.
- Only the first frame of an animated WebP is kept.
- Browsers will not display a 3GP, so it downloads rather than opening in a tab.
- One 3GP limitation to keep in mind: low resolution and heavily compressed by design.
Questions about WebP to 3GP
Will I lose transparency converting WebP to 3GP?
Yes. A 3GP cannot hold transparency, so anything see-through comes out on a solid colour, white unless you choose another. If the transparency matters, convert to PNG or WebP instead, and only flatten once you know what the image will sit on.
What happens to an animated WebP?
3GP holds a single image, so only one frame survives, normally the first. If you need the motion, convert to a format that keeps it such as MP4, WebM or WebP rather than to 3GP.
Can I open a 3GP in a browser?
No. No mainstream browser renders 3GP natively, so it will download rather than display. That is fine when the file is heading into desktop software or an archive, and a problem if it is going on a web page.
Is my WebP file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your WebP is read straight from your own disk, converted on your machine and handed back as a 3GP. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several WebP files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate 3GP downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
