Supports: 3GPP
Turn an old .3gpp phone clip into an animated GIF that loops and embeds anywhere — a chat thread, a forum post, an email, a family-history page. .3gpp is the GSM-era mobile container that most modern players refuse to open inline; GIF has been decodable by essentially every image viewer built since 1987. The honest catch is that a GIF cannot look better than its source, and feature-phone footage is small and soft to begin with, so what you are buying is shareability, not fidelity. Set the frame rate, cap the resolution, and download — no sign-up, no watermark.
.3gpp clips — saved MMS attachments, Nokia / Sony Ericsson / early-Samsung recordings, footage dumped off a camera card. Batch is supported, so drop several at once and they all run with the same settings..gif. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — never shared, never made public.| Property | 3GPP (.3gpp / .3gp) |
GIF |
|---|---|---|
| Created by | 3rd Generation Partnership Project, spec TS 26.244, April 2003 | CompuServe, released 15 June 1987; GIF89a added animation delays and transparency in 1989 |
| Built on | MPEG-4 Part 12, the ISO base media file format | A standalone image format |
| Video compression | H.263, MPEG-4 Part 2, or H.264 — all with motion compensation | LZW, lossless, with no motion compensation at all |
| Colour per frame | 24-bit, up to 16.7 million | 256 from a per-frame palette |
| Audio | Yes — AMR-NB, AMR-WB, or AAC-LC | None whatsoever |
| Typical capture size | Commonly 176×144 (QCIF) or 320×240 (QVGA) | Whatever you set |
| Plays inline in | VLC and a handful of desktop players | Every browser, chat client, and email reader |
| Looping | Not built in | Automatic, and controllable |
The compression row is the one that explains everything else. A video codec stores mostly the differences between frames; GIF stores frames. That is why a .3gpp is small and why the GIF made from it is normally several times larger — animated GIFs run roughly five to ten times the size of the same content encoded as MP4.
| Lever | Where it lives | What it does to the size |
|---|---|---|
| Duration | Trim the clip before converting | The strongest lever — with no motion compensation, bytes scale close to linearly with length |
| FRAMERATE | Advanced Options, default 10 FPS | Halving the frame rate roughly halves the frame count and therefore the file |
| Quality preset | File Compression, default High | Each step down discards more per-frame detail before the palette is built |
| Max file size | File Compression | Caps the output — a percentage of the source's size, an exact value, or a Discord/Email/Forum preset |
| Image resolution | File Compression → Custom, default Keep original | Bytes track pixel count, so a preset one step down cuts size sharply |
| Image quality (%) | File Compression → Custom, default 80 | Lower values discard per-frame detail before the palette is built |
If the result is still too large, run it through Compress GIF for a second pass, or reconsider the format — for anything longer than a few seconds, 3GPP to MP4 is smaller by an order of magnitude and keeps the sound.
No — a GIF cannot add detail that was never captured, and it will usually look slightly worse. Recordings from roughly 2002 to 2010 were commonly encoded at 176×144 (QCIF) or 320×240 (QVGA) with H.263 or MPEG-4 Part 2 at low bitrates so MMS messages stayed inside carrier limits, so the blocking is baked into the source samples. On top of that, GIF quantizes each frame down to 256 colours, which can add banding the original did not have. Leave the resolution untouched — or pick a small preset under File Compression → Custom — so you are not enlarging existing artifacts.
No. GIF has no audio track in the specification — there is nowhere to put it. The 3GPP soundtrack, usually AMR-NB speech at 8 kHz or AAC-LC on later handsets, is discarded. If the sound is what you need, extract it with 3GPP to MP3, or keep picture and sound together with 3GPP to MP4. If your goal is a silent loop that autoplays in a chat window or an email, that is precisely the case where GIF still beats video.
Because the two formats reach their size by opposite routes. H.263 and MPEG-4 Part 2 use motion compensation — each frame is largely described as a difference from the ones around it — and AMR audio adds only a few kilobits per second on top. GIF has no motion compensation at all; every frame is a full 256-colour image compressed with 1987-era LZW. A heavily compressed phone clip therefore expands, often several times over. Trim the duration first, then lower the frame rate, then the resolution.
.3gpp the same thing as .3gp?Yes. They are two filename spellings of the same container defined in 3GPP TS 26.244 for GSM-based handsets — same ISO base media structure, same codec list, same metadata. .3gp is the more common form in the wild. This page accepts .3gpp; for the shorter extension use 3GP to GIF and change nothing else. The similar-looking .3g2 is a different format — 3GPP2, built for CDMA2000 networks.
That is dithering. GIF allows at most 256 colours per frame, so anything with gradients — sky, skin tones, a dim indoor scene — has to be approximated, and dithering scatters pixels of the available colours to fake the missing ones. It reads as grain. Raising the File Compression Quality preset reduces it, at the cost of a larger file, because the encoder gets more palette room per frame; lowering the resolution also helps because there are fewer pixels for the pattern to show in. If clean gradients matter more than universal compatibility, 3GPP to APNG keeps full 24-bit colour instead.
Match the source rather than maximising it. Most legacy 3GPP footage was captured between 7.5 and 15 fps, so the default 10 FPS is a good starting point: it reproduces the motion that exists without writing redundant frames. Setting 30 fps on a 15 fps source does not make the animation smoother — the converter simply duplicates frames, and because GIF stores each one, you pay full price in bytes for information that is not there. Going the other way, 5 fps halves the size and looks noticeably steppier.
Small enough for most upload limits, provided you attack duration first. Our converter writes one complete frame per output frame with no inter-frame prediction, so output size tracks frames × pixels × palette complexity almost linearly — cutting a six-second clip to three seconds roughly halves the file, and stepping the frame rate from 10 fps to 5 fps roughly halves it again. Because a 3GPP source is already low-resolution, raising the output width above the source buys nothing but bytes. If you only need one moment rather than motion, 3GPP to JPG produces a single still that is a fraction of the size.
Files are uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours. There is no account to create, no watermark on the output, and your clips are never shared, indexed, or made public. Because the work happens server-side, conversion speed does not depend on your computer — only the upload does, and a phone-era .3gpp is typically small enough that this finishes quickly even on a slow connection.
