TIFF to 3G2 Converter

How to Convert TIFF to 3G2 Online

1. Upload Your TIFF Files: Drag and drop, or click "+ Add Files" to pick one or many .tiff / .tif images. Multi-page TIFFs and batches are supported — each page or file becomes a frame in the output video.
2. Pick Merge Strategy and Image Duration: Choose "Merge images" to stitch every TIFF into one 3G2 slideshow, or "Video per image" to emit a separate 3G2 per input. Set Image Duration (default 5 seconds per frame; presets range from 1/60s up to 10s per frame).
3. Adjust Codec, Resolution, Background (Optional): Under Advanced Options the Video Codec defaults to H.264 — the only widely played option for 3G2 alongside H.263 and MPEG-4 Part 2. Pick a Quality Preset (Very High is default), a Video Resolution preset (768p, 1080p, or custom width/height with aspect-ratio lock), and a Background Color (Black default) for letterboxed frames when TIFF aspect ratios don't match the output.
4. Convert and Download: Click "Convert" and grab your .3g2 file. Files process on our servers, are auto-deleted after the session, and there's no watermark or sign-up.

Why Convert TIFF to 3G2?

TIFF (Tagged Image File Format) is a flexible raster container favored by scanners, prepress, archival imaging, and microscopy — single files can hold multiple pages or layers at full bit depth, often uncompressed or losslessly compressed with LZW or ZIP. 3G2 (defined by 3GPP2 in spec C.S0050, initial release January 2004) is a CDMA2000-targeted multimedia container that wraps a small H.263, MPEG-4 Part 2, or H.264 video stream with low-bitrate audio for legacy mobile playback. Turning a TIFF stack into 3G2 is how you make a still-image sequence playable on older CDMA handsets, kiosks, MMS pipelines, or any device that only speaks the 3GPP2 ISO base media file format.

• Legacy CDMA handsets and kiosks — Verizon, Sprint, US Cellular, and KDDI (Japan) feature phones from the 2004-2012 era expect 3G2 over CDMA2000. A scanned product brochure or signage TIFF turned into a short 3G2 clip plays natively on these devices without re-encoding on the handset.
• MMS slideshow delivery — multimedia messaging gateways for CDMA networks accept 3G2 attachments under tight size caps (often 300 KB-1 MB). Converting a few TIFFs to a compressed 3G2 keeps the slideshow under the gateway limit.
• Embedded medical and industrial viewers — older ultrasound consoles, dental imaging stations, and machine-vision panels with CDMA modems sometimes only decode 3GPP2-family containers. A TIFF scan converted to 3G2 surfaces inside the viewer's playlist.
• Archival and forensic playback chains — court exhibits or insurance claims captured as multi-page TIFFs sometimes need to be replayed on the original evidence device, which may only be a 2009-vintage CDMA tablet. 3G2 preserves that compatibility.
• Multi-page TIFF flattening to a single shareable file — even outside CDMA contexts, a 40-page scanned TIFF is awkward to share; a 3G2 slideshow at 1 frame per 5 seconds turns the same content into one ~1-3 MB video file that any 3G2-capable player can step through.
• Test fixtures for codec/container validation — QA teams building 3GPP2-compliant playback stacks need short, deterministic 3G2 samples. TIFF input gives them pixel-perfect source frames before the conversion adds the container overhead they want to test.

TIFF vs 3G2 — Format Comparison

Codec Quick Guide for 3G2 Output

For the audio track xconvert defaults to AMR Narrow Band (8 kHz, 4.75-12.2 kbps) since image-to-video conversions normally produce a silent slideshow — the AMR stream is effectively empty filler that satisfies the 3G2 container requirement for many players. If you want stereo audio, use TIFF to MP4 and merge an audio track separately.

Frequently Asked Questions

Why convert a TIFF to 3G2 instead of MP4?

You'd only pick 3G2 if your target device is a CDMA2000 feature phone, an older kiosk, or an MMS gateway that requires 3GPP2 framing. For anything modern (smartphones, tablets, desktop browsers, social media) MP4 plays everywhere and produces smaller files. If you're not sure your destination needs 3G2 specifically, try TIFF to MP4 or TIFF to MOV instead.

Will my multi-page TIFF become one frame per page?

Yes. When "Merge images" is selected, each page of a multi-page TIFF becomes one frame in the 3G2 video, in document order. Set Image Duration to control how long each page is held — 5 seconds per frame is the default. Single-page TIFFs become single-frame videos of the chosen duration.

What's the maximum resolution I should use for 3G2?

3G2 is a low-resolution container by design — most CDMA handsets cap decode at QCIF (176×144), CIF (352×288), or QVGA (320×240). xconvert defaults to 768p, which works on modern 3G2-capable software players (VLC, MX Player) but may be rejected by older hardware. For genuine feature-phone targets, drop to 320×240 or 176×144 in the Video Resolution preset.

Does 3G2 support transparent backgrounds from my TIFF's alpha channel?

No. 3G2 video uses YUV 4:2:0 with no alpha plane. Any transparent pixels in your TIFF are composited against the Background Color (Black by default; pick White, Gray, or any of 24 named colors in Advanced Options). If you need transparency in the output, you need an image-output format with alpha like TIFF to PNG or TIFF to WebP.

Why is my 3G2 file rejected by an older Verizon or Sprint phone?

The most common cause is codec choice — pre-2010 CDMA handsets often only decoded H.263 or MPEG-4 Part 2 inside 3G2, not H.264. In Advanced Options, change Video Codec to H.263, drop the resolution to 176×144 (QCIF) or 320×240 (QVGA), and try again. The other common cause is bitrate ceilings — some handsets reject anything above 384 kbps video.

Is the conversion lossy? My TIFF was uncompressed and pristine.

Yes, going from TIFF to 3G2 always re-encodes pixels with a lossy video codec (H.264, MPEG-4 Part 2, or H.263). There's no lossless mode for 3G2. If preserving every pixel matters, keep a TIFF master and only generate 3G2 as a delivery copy. The Quality Preset dropdown (Very High → Very Low) trades file size against visible artifacts on the re-encode.

Can I add background music or narration to the slideshow?

Not in this tool — xconvert's image-to-3G2 path produces a silent video (with a placeholder AMR audio stream for container compliance). To attach real audio, first convert your TIFFs to MP4 with TIFF to MP4, then use a video editor to merge an audio track. 3G2's AMR-NB audio is narrowband (8 kHz sample rate, mono) and not suited to music anyway — for spoken narration on CDMA targets it works fine, but you'll need to mux the AMR stream in externally.

Why does my 3G2 file still seem large for a few images?

3G2 with H.264 is efficient for motion video but inefficient for slideshows of static frames — every frame is encoded against the previous, and abrupt full-frame changes (slide-to-slide cuts) generate large keyframes. Lowering the Quality Preset, dropping resolution, and increasing frame duration (so fewer keyframes per minute) all reduce file size. For a single static image, TIFF to JPG at a tenth the bytes is almost always the better answer.

Is the conversion done in my browser or on your servers?

Image-to-video conversions run server-side because they need FFmpeg with the H.263/H.264/AMR encoders. Your TIFFs are uploaded over HTTPS, converted, served back as a download, and deleted from our servers after the session ends. No account is required and there's no watermark.
