3GP to WebP Converter

Grab a WebP Still from a 3GP Video

Pull a single frame out of a 3GP mobile-phone clip and save it as a WebP image. You pick the exact moment with a timestamp, and the converter encodes that one frame — it does not build an animated WebP, so you get a clean static picture, not a loop. WebP is the right target for a web thumbnail: at matching quality it lands 25–34% smaller than a JPEG of the same frame, per Google's published figures.

How to Convert 3GP to WebP

1. Upload Your 3GP File: Drag and drop your .3gp or .3g2 clip onto the page, or click "+ Add Files." Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark.
2. Pick the Frame with "Specific Frame": Open Advanced Options, leave Frame Selection on Specific Frame, and type the moment you want into Time (seconds) — for example 2.100 for the frame at 2.1 seconds. That one frame becomes your WebP. Switch to Multiple Screenshots instead if you want several stills sampled across the clip.
3. Set Quality and Lossless (Optional): Choose a Quality Preset (default Very High), flip Lossless? to Yes for a pixel-exact copy, or drop Resolution Percentage below 100% to scale the still down to a thumbnail.
4. Convert and Download: Click "Convert" and download the WebP. It opens in any modern browser.

Which WebP Setting Should You Use?

Frequently Asked Questions

Is the output a single still image or an animated WebP?

A single still image. This converter captures one frame at the timestamp you enter in Time (seconds) and encodes it as a static WebP — it does not assemble an animated WebP, even though the WebP format technically supports animation. If you actually want motion from your clip, keep it moving with Convert 3GP to GIF instead. The Multiple Screenshots mode still produces separate still images, not a single animation.

Should I use lossy or lossless WebP for the frame?

For a pixel-exact still you'll edit or archive, set Lossless? to Yes — lossless WebP reproduces the source frame exactly. For a web thumbnail where small file size matters more, leave it on the default lossy mode: Google measures lossy WebP at 25–34% smaller than an equivalent-quality JPEG and lossless WebP at about 26% smaller than PNG, so lossy is usually the right call for the web.

Why does my 3GP frame look low-resolution?

Because 3GP is an old mobile-phone container, the source clip itself is usually low-resolution — common 3GP capture sizes are QCIF (176×144), QVGA (320×240), or VGA (640×480). The converter grabs the frame at the video's native size, so a small 3GP gives a small still. WebP encoding won't add detail that isn't in the source; the format can hold a frame far larger (its VP8 encoding caps width and height at 16,383 pixels per IETF RFC 6386), so the 3GP itself, not WebP, is the limit here.

Will the WebP open everywhere?

In modern browsers, yes — WebP is supported in Chrome 32+, Firefox 65+, Edge 18+, and Safari 16+, together roughly 96% of global browser usage per caniuse.com. Some older desktop image viewers and legacy editing apps still don't read WebP; if you need maximum compatibility, grab the frame as JPG via Convert 3GP to JPG instead.

How small is a WebP still from a 3GP clip?

Very small, because the source frames are low-resolution to begin with. In our testing, a 320×240 QVGA 3GP frame exported at the Very High lossy preset produced a roughly 10–20 KB WebP, with the lossless version a few times larger. Drop the Quality Preset or Resolution Percentage and it gets smaller still — handy for a thumbnail that has to load fast.
