3GPP to WebP Converter

Convert 3GPP to WebP Online

This tool grabs a frame from a .3gpp video — the old GSM-phone clip format — and saves it as a WebP image. A .3gpp file is the same container as a .3gp file: both are the 3GPP-defined mobile format built on the ISO base media file format (MPEG-4 Part 12), and the extension is just an alias, so a clip you grabbed off an old Nokia or Samsung handset works the same here whichever name it carries. The output is a single still WebP, not an animation — WebP lossy images run 25-34% smaller than the equivalent JPEG, which makes a 3GPP frame a tidy thumbnail or web preview.

How to Convert 3GPP to WebP

1. Upload Your 3GPP File: Drag and drop your .3gpp or .3gp 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.
2. Pick the Frame with "Specific Frame": Open Advanced Options and type a timestamp into the Time (seconds) field — 2.100 grabs the frame at 2 seconds and 100 milliseconds. That one frame becomes your WebP. Switch to Multiple Screenshots if you want several stills sampled across the clip instead.
3. Set Quality and Lossless (Optional): Leave Quality Preset on Very High, flip Lossless? to Yes for a pixel-exact copy, or scale the picture down with Resolution Percentage.
4. Convert and Download: Click "Convert" and download the WebP. No sign-up, no watermark.

3GPP Frame to WebP vs Other Image Formats

Frequently Asked Questions

Is a .3gpp file different from a .3gp file?

No — they are the same container under two names. The 3GPP file format is defined by the Third Generation Partnership Project on top of the ISO base media file format (MPEG-4 Part 12), and .3gpp is simply an alias of .3gp (MIME type video/3gpp for both). A clip that arrived with the longer extension holds the same H.263, MPEG-4 Part 2, or H.264 video and AMR or AAC audio as any .3gp. If your file uses the shorter extension, Convert 3GP to WebP is the identical tool.

Does this output a single still WebP or an animated WebP?

A single still image. The converter captures one frame at the timestamp you enter in Time (seconds) and encodes it as a static WebP — it does not build animated WebP. WebP can hold animation, but this tool does not, so for motion keep the clip as video with Video Cutter.

Will the WebP open on my phone and in browsers?

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

Why does my extracted frame look soft or blocky?

Two reasons stack here. 3GPP video was built for 2G/3G bandwidth, so the source is often low-resolution (176×144 or 320×240) and already lossy — extracting a frame can't add detail the recording never had. On top of that, the WebP default is lossy; set Lossless? to Yes or raise Quality Preset to avoid adding a second round of compression on top of the source.

How big is the WebP I get out of a 3GPP clip?

Small. In our testing, a 320×240 frame from a 3GPP clip exported at the Very High preset produced a roughly 10-20 KB lossy WebP, with the lossless version a few times larger. The frame is captured at the video's native resolution, and you can shrink it further with Resolution Percentage for a lighter thumbnail.
