3G2 to AVIF Converter

Extract a 3G2 Frame to AVIF Online

This tool grabs one still frame out of a .3g2 video and saves it as an AVIF image — the AV1-coded still format that lands roughly 30-50% smaller than JPEG at the same visual quality. .3g2 is the 3GPP2 container that old CDMA phones (Verizon- and Sprint-era US handsets) recorded to, so the usual job is rescuing a memorable moment off a long-dead phone. It does not re-encode the moving clip: you pick a timestamp and get a single picture. Be clear on the catch up front — feature-phone video is tiny and heavily compressed, so the still will be small and soft because the source is, and AVIF cannot add resolution or detail the phone never captured.

How to Convert 3G2 to AVIF

1. Upload Your 3G2 File: Drag and drop your .3g2 (or .3gp) file onto the page, or click "+ Add Files" to browse. You can queue several clips and they all process with the same settings.
2. Pick the Frame with "Specific Frame": Under Frame Selection, choose Specific Frame and enter the moment in Time (seconds) — for example 2.5 for the frame at two and a half seconds. That one frame becomes your AVIF.
3. Set Quality and Size (Optional): Leave Quality Preset on Very High (Recommended) for a near-lossless still, or pick Specific file size to cap the output; use Resolution Percentage, Preset Resolutions, or Width x Height to scale the frame down.
4. Convert and Download: Click "Convert" and download your AVIF image. No sign-up, no watermark.

What You Get From a 3G2 Frame Grab

Frequently Asked Questions

Will converting to AVIF make my old 3G2 frame look sharper or higher-resolution?

No — and this is the honest catch. AVIF is a more efficient codec, so it stores the same picture in a smaller file with fewer compression artifacts than JPEG. But the frame you start with is whatever the 3G2 already held, often around QCIF (176×144) and heavily compressed for an early CDMA network. AVIF cannot add detail or resolution the original never captured; you get a cleaner-compressed copy of an existing low-resolution still, not an upscaled one. Enlarging it past its native size only stretches the existing pixels.

Is the output a still AVIF or an animated one?

A single still image. AVIF can technically hold animation because it is built on the AV1 video codec, but this tool extracts one frame at the timestamp you set under Frame Selection and encodes it as a static picture. If you want several stills, switch to Multiple Screenshots, which samples frames across the clip and returns them together in a ZIP. If you want the moving clip in a modern playable format instead, use Convert 3G2 to MP4.

My 3G2 came off an old Verizon or Sprint phone — will this still work?

Yes — that is the main use case. .3g2 is the 3GPP2 format CDMA2000 carriers used, which in the US meant Verizon and Sprint. Verizon completed its CDMA network shutdown on December 31, 2022, so the network those clips came from is gone, but the files still convert fine. The same pipeline also accepts .3gp from GSM-era phones; for those, the 3GP to AVIF converter covers the GSM twin.

Which browsers and devices can open an AVIF file?

AVIF is supported by about 93% of browsers in use today, per caniuse.com: Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+ (macOS Ventura / iOS 16.4, from 2023). Older browsers and some desktop image viewers won't open it. If you need a still that opens anywhere — including legacy apps and email — extract the frame as JPG instead via Convert 3G2 to JPG.

How are my files handled, and how long are they kept?

Your 3G2 is uploaded over an encrypted (TLS) connection, processed on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark on the output, and your files are never shared or made public. In our testing, a frame pulled from a QCIF 3G2 clip at the Very High preset came out as a single AVIF image of only a few kilobytes — these stills stay tiny because the source resolution is tiny.
