MJPEG to DivX Converter

Convert MJPEG to DivX Online

MJPEG (Motion JPEG) stores every frame as a full, independent JPEG with no compression between frames, so a clip of any length stays large. DivX is an MPEG-4 Part 2 video codec that adds interframe compression — it reuses what stays the same from one frame to the next — so converting MJPEG to DivX typically produces a much smaller file at similar visual quality. This is a re-encode, so expect a small one-time generation loss, but the size savings on motion footage are usually dramatic.

How to Convert MJPEG to DivX

1. Upload Your MJPEG File: Drag and drop your .mjpeg clip onto the page or click "+ Add Files" to browse. You can queue several files and convert them with the same settings.
2. Set the Quality Preset: Open "Show All Options" and choose a "Preset" under File Compression — "Very High (Recommended)" balances size and clarity. Lower presets shrink the file further at the cost of fine detail.
3. Adjust Resolution or Target Size (Optional): Use "Video resolution" to downscale (for example to 720p) or "Specific file size" to hit an exact megabyte target; both shrink the output before encoding.
4. Convert and Download: Click "Convert" and download your DivX AVI. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.

DivX vs MP4 (H.264): Which Target Should You Choose?

DivX is the right target if you specifically need an AVI that plays on an older DivX-Certified DVD/Blu-ray player or legacy media box. For everything else — phones, browsers, editors, smart TVs — MP4 with H.264 is the more efficient and more universally compatible choice.

If your goal is the smallest, most compatible file rather than DivX specifically, convert MJPEG to MP4 instead.

Frequently Asked Questions

Will converting MJPEG to DivX actually make the file smaller?

Usually yes, and often by a large margin. MJPEG repeats a full JPEG for every frame and never compares one frame to the next, while DivX (MPEG-4 Part 2) only stores what changes between frames. On typical motion footage MJPEG can occupy roughly 5–20x the space of an interframe codec, so the DivX output is normally a fraction of the source size at comparable quality.

Will I lose quality converting MJPEG to DivX?

There is a small, one-time generation loss because DivX re-encodes the video with lossy interframe compression rather than copying the original JPEG frames. At the "Very High" preset the difference is hard to spot on normal content. If you need to keep editing frame-by-frame afterward, keep an MJPEG master and use the DivX copy only for storage and playback.

Should I convert to DivX or to MP4 instead?

Choose DivX only if you need to play the file on an older DivX-Certified DVD/Blu-ray player or set-top box that expects a DivX AVI. For phones, browsers, modern TVs, and video editors, MP4 with H.264 compresses better and plays almost everywhere. In our testing, the same source converted to MP4/H.264 was consistently smaller than the DivX AVI at a matched quality preset.

What audio does the DivX output use?

A DivX AVI traditionally pairs MPEG-4 Part 2 video with MP3 audio, and that is the default this converter applies. The audio from your MJPEG source is re-encoded to match the DivX container.

What plays a DivX AVI file?

VLC, MPC-HC, and most desktop media players handle DivX AVI out of the box on Windows, macOS, and Linux. Hardware DivX-Certified DVD and Blu-ray players also play it directly. If a player refuses the file, converting DivX to MP4 makes it universally compatible.

Is there a file size limit, and is my upload private?

Large MJPEG files are practically limited by upload time rather than a hard device cap. Your file is sent over an encrypted connection, converted on our servers, and deleted automatically after a few hours — never shared, never made public, and no sign-up or watermark is required.
