MP4 to DivX Converter

How to Convert MP4 to DivX Online

1. Upload Your MP4 Files: Drag and drop or click "+ Add Files" to select MP4 (or M4V) clips from your computer. Batch is supported — drop in a whole folder and each file converts independently.
2. Pick Quality Preset or Bitrate Mode: Default is the "Very High (Recommended)" Quality Preset. Switch to Specific file size to cap output at an exact MB target (useful for fitting a single CD-R / 700 MB or a 4.7 GB DVD-R), Constant Bitrate for predictable per-second sizing, Variable Bitrate for smaller files at the same quality, Constant Quality for a fixed CRF, or Constraint Quality for a capped VBR ceiling. Most DivX-certified hardware was designed around MPEG-4 ASP bitrates in the 1–4 Mbps range.
3. Set Resolution and Trim (Optional): Under Video resolution, keep original, pick a Preset Resolution (1080p / 720p / 576p / 480p / 360p / 240p), scale by Resolution Percentage, or enter Width × Height. Most legacy DivX-certified DVD players were SD-era hardware, so 720×480 (NTSC) or 720×576 (PAL) is the safe target. Under Trim, select Time Range to keep only the portion you need before encoding.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no email required. Download individually or as a ZIP.

Why Convert MP4 to DivX?

DivX is an MPEG-4 Part 2 Advanced Simple Profile (ASP) codec released by DivXNetworks in 2001, with a FourCC of DX50 since version 5.0. It became famous in the early-2000s file-sharing era for compressing a full DVD movie onto a single 700 MB CD-R, and it shipped on hundreds of millions of "DivX Certified" consumer devices — DVD players, set-top boxes, car head units, even some Blu-ray players and televisions from the late 2000s. Today, modern smartphones, smart TVs, and computers play H.264 / H.265 inside an MP4 container natively, so the only reason to convert MP4 to DivX is hardware compatibility with that legacy device fleet. Common scenarios:

• Older standalone DVD players (2003-2010) — The first DivX-certified DVD players (KiSS DP-450 / DP-500) shipped in March 2003, and through about 2010 Pioneer, Philips, Panasonic, Samsung, LG, Sony, and Toshiba all sold DivX-certified models. These players decode MPEG-4 ASP (DivX / Xvid) from a burned DVD-R or USB stick but cannot decode H.264, HEVC, or AV1. Re-encoding your MP4 to DivX at SD resolution is what makes those discs play.
• Car head units and in-flight entertainment from that era — Many factory in-car DVD systems and aftermarket head units shipped between roughly 2005 and 2012 advertised "DivX playback" from USB and burned media. Some commercial IFE systems on aircraft delivered before the H.264 transition were also keyed to DivX / Xvid.
• DivX-certified Blu-ray players and HTPCs — Pioneer, Panasonic, Marantz, and Denon released DivX-certified Blu-ray players late in the 2000s. These will play H.264 MP4 from disc, but a side library of DivX files from older sources still benefits from staying in the DivX container for menu/index compatibility.
• PlayStation 3 — The PS3 has long supported DivX/Xvid playback in addition to MP4 / H.264. For a mixed disc of legacy content it can be useful to stay in the DivX codec rather than re-encode every file.
• Fitting movies to a CD-R or DVD-R — DivX's claim to fame was compressing a feature film to roughly 700 MB while staying watchable at SD resolution. If you're burning archive discs for a player that only reads optical media, DivX hits the size budget at acceptable quality.
• Replacing a damaged DivX original — If a workflow downstream expects the .avi (DivX/Xvid) container — old editing software, a kiosk player, a museum exhibit — re-encoding the MP4 source to DivX produces a drop-in replacement.

MP4 vs DivX at a Glance

DivX vs Xvid vs H.264 — Codec Quick Guide

For DivX-certified hardware, output in the .avi container with the DX50 FourCC is the most broadly accepted profile. If your target also accepts Xvid you can use either — most DivX-certified players honor both.

If you need the reverse direction see DivX to MP4. Need an Xvid file instead? Use MP4 to Xvid. To shrink an existing DivX further, use Compress DivX.

Frequently Asked Questions

Will my modern smart TV or phone play the DivX file?

Usually no. Modern Android phones, iPhones, smart TVs (2018 and newer), and current browsers ship H.264 / HEVC / AV1 decoders and do not include MPEG-4 ASP. VLC and MPV play DivX on any platform; the DivX Player desktop app (Windows / macOS) also plays it. If your only goal is playback on a modern device, stay in MP4 — convert to DivX only when the target hardware specifically requires it.

Will DivX files be larger than the MP4 source?

Often yes. H.264 is roughly twice as efficient as MPEG-4 ASP, and HEVC is roughly four times as efficient, so a 100 MB H.264 MP4 will typically land in the 180-260 MB range when re-encoded to DivX at visually equivalent quality. That's a feature, not a bug — the legacy hardware you're targeting was designed around 1-4 Mbps ASP bitrates and cannot decode the more efficient modern codecs.

Should I use DivX or Xvid?

If your hardware is specifically DivX-Certified, output DivX (FourCC DX50) inside .avi. Most DivX-certified players also accept Xvid (FourCC XVID), which uses the same MPEG-4 Part 2 ASP base but is open-source and free of DivX's licensing layer. If the player labels itself "DivX / Xvid" both will work; if it only says "DivX", stick with DX50 to be safe. See MP4 to Xvid for an Xvid-specific export.

What resolution should I pick for a DVD player?

DivX-certified standalone DVD players are SD-era hardware. Use 720×480 (NTSC, North America / Japan) or 720×576 (PAL, Europe / most of the rest of the world) for full-screen playback. Some certified Blu-ray players accept HD DivX up to 1080p, but if you're not certain about the target, SD is the safe default. The "480p" preset under Video Resolution matches NTSC; pick "576p" for PAL.

Will my burned DVD-R or USB drive actually play?

Two requirements beyond just the codec: the disc has to be readable by the player (most modern players read DVD-R and DVD+R; older ones are pickier), and the filesystem has to be supported (FAT32 is universal, exFAT and NTFS often aren't). Keep filenames short and ASCII, avoid deeply nested folders, and burn at a moderate speed (4× to 8×) for the highest read reliability on older drives.

Is DivX still being developed?

The MPEG-4 Part 2 DivX codec hasn't received a meaningful update in years — the most recent version of the codec itself was 6.9.2, with the brand later expanding into DivX Plus HD (an H.264 profile) and DivX HEVC Ultra HD. DivX, LLC was acquired by Fortress Investment Group in February 2018. The codec format itself is stable and still plays on all DivX-Certified hardware ever shipped.

Can I convert multiple MP4 files to DivX at once?

Yes. Upload as many MP4 files as you want — there's no quantity limit. Apply the same settings to all of them or set per-file options. Each file converts in parallel within your browser session and downloads individually or as a single ZIP.

Can I trim or split the video while converting?

Yes. Under Trim, select Time Range and enter a start time and duration. Both fields accept seconds or HH:MM:SS.sss format. Trimming first skips unwanted footage before encoding, which speeds up the convert step and reduces output file size — useful when targeting a CD-R or DVD-R capacity. For more advanced cutting see Video Cutter.

What if my MP4 came from an iPhone or modern camera?

Modern iPhones record either H.264 or HEVC inside an .mov or .mp4 container, often at 1080p or 4K with high bitrates. Converting that footage to DivX involves both a codec change (H.264/HEVC → MPEG-4 ASP) and usually a downscale to SD, so expect significantly slower encoding than a simple remux. If you only need the file to play on a modern device, you don't need DivX at all — keep it as MP4 or use Compress MP4 to shrink it.
