Supports: 3GP, 3G2
Turn an old .3g2 clip from a CDMA flip phone into an animated GIF that loops and plays everywhere — Discord, Reddit, Slack, email, a forum post, a family-history page. 3G2 is the 3GPP2 container Verizon, Sprint, and other CDMA carriers used, and modern players often choke on its EVRC/QCELP voice codecs; GIF plays inline in every browser and chat client made in the last three decades. The honest catch: a GIF can't add detail the phone never captured, so a tiny QCIF/QVGA recording becomes a small, slightly blocky loop — and because GIF stores frames at 256 colors with no motion prediction, the GIF can end up larger than the original 3G2.
.3g2 (or .3gp) clips — saved MMS attachments, old CDMA-handset recordings, dumped camera-card footage. Batch is supported; drop several at once.| Property | 3G2 (.3g2) | GIF |

| Video coding | H.263, MPEG-4 Part 2, or H.264/AVC | LZW over indexed frames, no motion prediction |
| Audio | EVRC, EVRC-B, EVRC-WB, QCELP (13K), SMV, VMR-WB, AMR, AAC-LC | None — GIF has no audio track |

The output is a fully animated GIF — every sampled frame of the clip, looping — not a single still. A 3G2 is small because H.263 / MPEG-4 motion compensation plus a low-bitrate CDMA voice track squeeze it hard. GIF throws that away: each frame is an indexed-color image, so this is one of the rare conversions where the result can outweigh the source.
| Goal | Setting to change | What it does |
|---|---|---|
| Smaller file | FRAMERATE → lower (10 FPS or below) | Fewer stored frames; the single biggest lever on GIF size |
| Hard byte ceiling | File Compression → Max file size | Caps the output at a percentage of the source's size, an exact value, or a Discord/Email/Forum preset |
| Smaller file, keep size on screen | File Compression → lower the Quality preset | Rung-by-rung quality-for-size trade; palette handling stays automatic |
| Smaller file, keep motion | File Compression → Custom → Image resolution ("Preset Resolutions" 240p / 144p) | Fewer pixels per frame; safe when the source was QCIF/QVGA anyway |
| Fine-grained size control | File Compression → Custom → Image quality (%) → lower the slider | Gradual quality-for-size trade without touching dimensions |
| Most faithful loop | Leave the defaults — FRAMERATE 10 FPS, resolution untouched | No upscaling, no invented pixels |
| Exact pixel dimensions | File Compression → Custom → Image resolution → "Width x Height" | Useful when a forum or wiki caps embedded image width |
Upscaling is the one setting that never helps: a 176×144 recording rendered at 720p is the same picture with softer edges and several times the bytes. If the GIF is still too heavy after tuning, trim the clip to the seconds that matter, then run the result through Compress GIF.
Animated. This tool reads the clip and writes its frames into a looping GIF, with the FRAMERATE dropdown (default "10 FPS (Recommended)") controlling how many frames per second get sampled — it is not a one-frame screenshot. If you specifically want one still image instead of a loop, use 3G2 to JPG, which grabs a single frame at a timestamp you choose.
No, and no converter can change that: GIF has no audio track in the specification at all. Whatever the clip held — EVRC, QCELP, AMR, or AAC — is dropped when the frames become an image file. If the sound is the part you care about, convert the same file with 3G2 to MP3 or 3G2 to M4A and keep both outputs.
Because the two formats get small in opposite ways. 3G2 leans on inter-frame video compression — H.263, MPEG-4 Part 2, or H.264 describe how a frame differs from the one before — plus a voice codec that costs only a few kilobits per second. GIF stores each frame as its own indexed-color image compressed with 1987-era LZW and has no motion prediction, so a few hundred kilobytes of 3G2 can expand into a multi-megabyte GIF. Cut the duration first, drop the FRAMERATE, then reduce resolution.
Usually the audio. 3G2 is the 3GPP2 (CDMA) variant, and it can carry voice in EVRC, EVRC-B, EVRC-WB, QCELP (13K), SMV, or VMR-WB — vocoders many desktop players never shipped, which is why you get silence, an error, or a refusal to open. Our server-side decoders handle those streams during conversion. Because GIF has no audio track, an unsupported vocoder stops mattering entirely once the file is converted.
.3g2 the same as .3gp?They are siblings, not twins. Both are structurally based on the ISO base media file format (ISO/IEC 14496-12), but 3GP came from 3GPP for GSM/UMTS phones and 3G2 came from 3GPP2 for CDMA2000 phones. 3G2 adds the CDMA vocoders (EVRC family, QCELP, SMV, VMR-WB) and, unlike 3GP, does not store HE-AAC v2 or AMR-WB+ audio. This tool accepts both; if your file uses the GSM-side extension, the twin page is 3GP to GIF.
Work in this order: trim to the seconds you actually need, set FRAMERATE to 10 FPS, then either switch File Compression to Max file size and grab the Discord (10 MB max) or Email (25 MB max) preset, or use File Compression → Custom to pick a 240p or 144p resolution preset and lower Image quality (%). Discord's free tier caps uploads at 10 MB, and mail providers commonly stop around 25 MB, so a short low-resolution loop clears both easily. Because a 3G2 source is already low-resolution, widening past its native size adds megabytes without adding clarity.
Keep the original. Old CDMA handsets typically recorded 176×144 (QCIF) or 320×240 (QVGA), and those pixel counts are the hard ceiling on detail — H.263 and MPEG-4 Part 2 encoded exactly what the sensor produced and nothing more. If you need the GIF to appear bigger on a page, scale it with CSS or the forum's own image sizing rather than baking an upscale into the file, which only costs bytes.
We set this page's FRAMERATE default to "10 FPS (Recommended)" because GIF pays full price for every frame it stores, and the source rarely justifies more. Legacy 3G2 recordings were captured at low frame rates to fit CDMA bandwidth budgets, so requesting 30 FPS mostly writes duplicate frames — a bigger file showing the same motion. Raise it only if the source is a modern high-frame-rate clip saved with a 3G2 extension.
It is uploaded over an encrypted connection, converted on our servers, and deleted automatically a few hours after the job finishes — never shared, never made public, and there is no sign-up or watermark. The practical limit on a long clip is upload time rather than anything on your end; if a file is slow to send, trimming it before conversion is the fastest fix.
