Drag or select your .avi: DivX movies, VHS-digitized home videos, DV camera recordings. FFmpeg.wasm supports DivX, Xvid, MJPEG, DV, and MPEG-4.
Re-encode to 3GP in the browser
The AVI is decoded (with any codec), resolution reduced to CIF (352×288) or QCIF (176×144), and re-encoded to H.264 Baseline in a 3GP container.

FAQ
Got questions?
The DivX movie collection many users have on external hard drives (AVI with DivX 3, 4, 5, or Xvid — the dominant video distribution format between 2000 and 2008) cannot be played on basic phones directly. Converting short clips from those AVIs to 3GP allows sharing specific moments or scenes with relatives who have basic phones, with no streaming or internet connection needed.
Yes. Home videos digitized from VHS with capture cards from the 2000–2010 era (AverMedia, Pinnacle, Dazzle) generally produce AVI with MJPEG or MPEG-4 Part 2 codec. FFmpeg.wasm decodes both without issues. This is especially useful for converting birthday, wedding, or family event clips originally recorded on VHS, digitized to AVI, and now to be shared with relatives who have basic phones.
Yes. Sony, Canon, Panasonic, and JVC miniDV camcorders from the 1995–2010 era generate AVI with DV codec (DV25, also known as DV-SD). FFmpeg.wasm correctly decodes DV25. A 1-hour DV AVI (13 GB) can be partially converted to 3GP by extracting short clips: use 2–5 minute clips given browser RAM constraints.
Yes, that is the primary use case. DivX (commercial, MPEG-4 Part 2 based, released in 2000 by DivXNetworks) and Xvid (open source, OpenDivX fork released in 2001) are the most common codecs in AVI collections from the 2000–2008 era. FFmpeg.wasm decodes them perfectly and re-encodes to H.264 Baseline CIF for 3GP.
At 128 kbps video plus 12.2 kbps AAC-LC mono audio, one minute of CIF 3GP is approximately 1 MB. At 256 kbps, about 2 MB. For MMS sending, clips should be 30–60 seconds to respect carrier MMS size limits (generally 300 KB–1 MB). For microSD or Bluetooth, the limit is available storage capacity.
The Nokia 6300 (Nokia Series 40 5th Edition, released 2006) and Nokia 5200 support 3GP video playback with H.264 Baseline up to CIF (352×288). The Samsung SGH-E250 (2007) supports 3GP with MPEG-4 Part 2 and H.264 Baseline in some markets. The Motorola RAZR V3 (2004) originally only supported H.263; some updated models accept MPEG-4 Part 2 but not always H.264 Baseline. For maximum RAZR V3 compatibility, MPEG-4 Part 2 would be safer, though H.264 Baseline is the converter's default.

AVI (Audio Video Interleave) is Microsoft's video container format, introduced in November 1992 with Windows 3.1 as part of the Video for Windows (VfW) technology. During the 1990s and the first decade of the 2000s, AVI was the dominant video format in the Windows ecosystem. The explosion of internet video distribution between 2000 and 2008 was dominated by AVI with DivX codec (released in 2000 by DivXNetworks, based on MPEG-4 Part 2) and Xvid (open source OpenDivX fork, released in 2001). During that period, most movies and series distributed over peer-to-peer networks (eMule, BitTorrent) were AVI DivX or AVI Xvid. Home video from the 1995–2010 period also massively adopted AVI: analog video capture cards of the 2000–2010 era (AverMedia A867, Pinnacle PCTV, Dazzle DVC 100) produced AVI with MJPEG, and miniDV camcorders (Sony DCR-HC, Canon DM-series, Panasonic NV-series, JVC GR-series) generated AVI with DV25 codec when transferring video to PC. The 3GP format was defined by the 3GPP consortium in 2001 for MMS video sending and playback on 3G phones with 128×160 to 320×240 pixel screens. Converting AVI to 3GP connects two eras of digital video history: the 2000s PC internet video era and the 2001–2012 basic phone video era.
The practical scenarios for AVI-to-3GP conversion in 2024–2026 are primarily three. First, the DivX/Xvid collection: millions of users have collections of DivX/Xvid AVI movies and series from the 2000–2008 era on external hard drives that were never deleted. Converting a short clip from those AVIs to 3GP allows sharing a memorable scene or the beginning of a movie with a relative who has a basic Nokia, with nothing to install on the recipient's phone. Second, VHS-digitized home video: many families digitized their VHS tapes during the 2000s, producing AVI files with MJPEG (the typical output format of analog capture cards). Those recordings of 1980s and 1990s weddings, baptisms, birthdays, and family vacations — now on hard drives as AVI MJPEG — can be converted to 3GP to share with the people in those recordings who today own a basic Nokia or Samsung. Third, miniDV video: the generation of parents and grandparents who filmed family events with miniDV cameras in 1995–2010 has collections of DV AVI (DV25 codec) representing the family's audiovisual memory. Extracting clips from those AVIs and converting to 3GP allows sending them via Bluetooth or microSD to elderly relatives' basic phones without streaming access.
Convertir.ai converts AVI to 3GP directly in the browser via FFmpeg.wasm without sending files to external servers. For AVI with DivX/Xvid (MPEG-4 Part 2), conversion to H.264 Baseline CIF is fast: 1–3 minutes for a 5-minute clip on modern hardware. For AVI with MJPEG (digitized home video), conversion is even faster since MJPEG is an intra-frame codec (each frame decoded independently) that FFmpeg.wasm decodes without requiring a temporal buffer. For AVI with DV25 (miniDV), the process is intermediate in speed. The result is a 3GP with H.264 Baseline Profile level 3.0 at CIF (352×288), video bitrate of 128–256 kbps, and AAC-LC mono audio at 12.2 kbps, compatible with Nokia Series 40 (Nokia 6300, 5200, 6101, 6300i and later models), Samsung SGH (SGH-E250, SGH-L760), Motorola (RAZR V8, MOTOKRZR K1), and Sony Ericsson W-series. Home videos in AVI MJPEG are especially privacy-sensitive — they contain unique and irreplaceable family memories — so FFmpeg.wasm's local processing without external server is the most important technical guarantee this tool provides: your video memories never leave your device during conversion.
