TIFF to 3G2 Converter

How to Convert TIFF to 3G2 Online

1. Upload Your TIFF Files: Drag and drop one image for a still slideshow, or upload a numbered batch (frame_001.tif, frame_002.tif...) for a true image sequence. Multi-page TIFFs and large LZW/Deflate-compressed files are both accepted.
2. Pick Duration, Merge Strategy, and Quality Preset: Set "Image Duration" to control how long each frame holds on screen (1/60 second up to 10 seconds per frame). Choose "Merge images" to stitch all frames into one 3G2, or "Video per image" to render one clip per TIFF. Under File Compression pick a "Quality Preset" — Very High is the default; Low or Lowest produces a smaller file better suited to CDMA bandwidth.
3. Set Resolution and Background (Optional): Pick "Keep original", a "Preset Resolution" (144p, 240p, 360p — sensible ceilings for 3G2), or enter custom Width x Height while keeping aspect ratio. Use the Background Color dropdown (default Black) to letterbox frames that don't match the target aspect.
4. Convert and Download: Click "Convert". The file is muxed into a 3G2 container with H.263 or MPEG-4 Part 2 video — no audio track unless you add one — and downloads to your browser. No sign-up, no watermark, no email gate.

Why Convert TIFF to 3G2?

TIFF (Tagged Image File Format) is the archival image of choice for scanners, microscopy, GIS, and prepress because it supports lossless LZW/Deflate compression, 16-bit channels, layers, and multi-page documents. 3G2 (3GPP2 file format) is a mobile-video container introduced in January 2004 by the Third Generation Partnership Project 2 for CDMA2000 networks — Verizon, Sprint, US Cellular, KDDI, China Telecom — and is structurally based on the ISO base media file format (MPEG-4 Part 12), the same container family as MP4. Converting TIFF frames into a 3G2 clip turns a still or a numbered sequence into a tiny, bandwidth-friendly video that plays on legacy CDMA feature phones and on multimedia messaging systems still routed through CDMA infrastructure.

• Legacy CDMA handset playback — Older Verizon, Sprint, and KDDI feature phones (pre-VoLTE Kyocera, LG, Samsung flip models) play 3G2 natively but reject MP4 or MOV. A scanned document or contact sheet exported from TIFF becomes viewable on the device's media gallery.
• Multimedia messaging archives — MMS gateways on CDMA networks historically transcoded outbound video to 3G2; recreating that pipeline lets you build matching reference files for legal-discovery, forensics, or carrier-testing work.
• Embedded systems and digital signage on tight bandwidth — Industrial controllers, in-vehicle infotainment, and 2G/3G IoT screens often ship with codecs limited to H.263 + AMR-NB; a 144p 3G2 of a TIFF schematic plays where an H.265 MP4 will not.
• Tiny shareable slideshows — A 5-second 3G2 of a single TIFF at 240p with no audio runs about 50-150 KB — small enough to round-trip through SMS-style attachment caps on legacy carrier gateways.
• Photo-to-video conversion for emulators and retro phone collectors — 3G2 is the canonical playback format for emulated BREW and pre-Android Samsung/LG feature-phone environments used by hobbyists and museum archives.
• Astrophotography and microscopy stacks — Scientific cameras export 16-bit TIFF sequences; rendering a quick 3G2 preview at 240p gives you a tiny shareable artifact while keeping the source TIFFs intact for analysis.

Frequently Asked Questions

Why convert TIFF to 3G2 instead of MP4?

MP4 is the modern default and works almost everywhere, but pre-VoLTE CDMA feature phones, some carrier MMS gateways, and certain embedded hardware only accept 3GPP/3GPP2 containers with H.263 or MPEG-4 Part 2 video. If you're targeting one of those environments — legacy Verizon Kyocera flip phones, KDDI Japan handsets, or older in-vehicle systems — 3G2 plays where MP4 fails. For modern phones, use TIFF to MP4 instead.

What's the difference between 3G2 and 3GP?

Both are derived from the ISO base media file format and share the same video codecs (H.263, MPEG-4 Part 2, H.264). The split is on the audio and carrier side: 3GP was defined by 3GPP for GSM/UMTS networks (T-Mobile, AT&T, most of Europe) and adds Enhanced aacPlus and AMR-WB+; 3G2 was defined by 3GPP2 for CDMA2000 networks and supports CDMA-specific audio codecs like EVRC, EVRC-B, QCELP (13K), SMV, and VMR-WB instead. If your target device is a CDMA handset, 3G2 is the safer container. See also TIFF to 3GP.

How long will each TIFF be on screen in the resulting 3G2?

Whatever you set in "Image Duration". Defaults to 5 seconds per frame; the dropdown goes from 1/60 second (effectively one video frame, useful for stop-motion) up to 10 seconds per frame. For a slideshow of 20 TIFFs at 5 seconds each, expect a ~100-second clip. Switch to "Video per image" if you want each TIFF as its own separate 3G2 file rather than a merged sequence.

Will my multi-page TIFF be treated as a sequence?

Yes — each page of a multi-page TIFF (common in fax archives, scanned documents, and TIFF/EP camera output) is read as a separate frame, the same as if you'd uploaded that many individual files. Combined with "Merge images", a 30-page scanned TIFF becomes a 30-frame 3G2 slideshow with whatever per-frame duration you choose.

Can I add a soundtrack to the 3G2?

This converter targets the image-to-video pipeline, so the output is video-only by default. To add an AMR-NB or AAC-LC audio track afterward (the two codecs most widely supported in 3G2), you can run the resulting 3G2 through a separate audio-mux step. Note that 3G2 does not support Enhanced aacPlus (HE-AAC v2) or AMR-WB+, so don't try to attach those — playback will fail on most CDMA handsets.

What resolution should I pick for legacy phone playback?

176x144 (QCIF) and 320x240 (QVGA) are the safest choices for genuinely old CDMA handsets — anything from roughly 2002 to 2010. Modern 3G/4G feature phones that still parse 3G2 (lower-end Nokia HMD, some KaiOS devices) handle up to 640x480 (VGA) reliably. Going higher than 480p inside a 3G2 wrapper is technically legal but defeats the format's purpose; use 3G2 to MP4 and switch container if you need HD.

Why is my 3G2 so small compared to the source TIFFs?

A single 24 MP TIFF saved as lossless LZW can be 70-100 MB; a 5-second 3G2 of that same image at 240p with no audio is typically under 200 KB. The reason is twofold: 3G2 stores video frames (already a tiny fraction of one TIFF's pixel count after H.263/MPEG-4 Part 2 quantization), and the codecs were engineered for sub-100 kbps CDMA channels. Detail loss is significant — 3G2 is a delivery format for legacy mobile, not an archival one.

Do I need to install anything, and where does the conversion run?

No installation. Files are uploaded over an encrypted connection to xconvert's processing servers for the FFmpeg-based muxing step (TIFF decoding plus H.263/MPEG-4 Part 2 encoding plus 3G2 muxing), then deleted automatically after a few hours. The page works in Chrome, Firefox, Edge, and Safari 14.1+ on desktop and mobile.
