Set the video quality in a VBR mode. Choose "Custom" if you need to set a fixed bitrate (CBR).
Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.
This option controls the number of frames per second. It changes the playback smoothness only, not the output video duration or video playback speed.

mjpeg

MJPEG (Motion JPEG) is a video compression format in which each frame is independently compressed as a separate JPEG image. Unlike interframe codecs that exploit temporal redundancy between successive frames, MJPEG treats every frame as a standalone photograph, applying the discrete cosine transform compression familiar from still image JPEG encoding. This approach dates back to 1992, coinciding with the establishment of the JPEG standard itself, and was widely adopted as one of the earliest practical methods for compressing digital video. The intraframe-only nature of MJPEG carries several practical benefits: any frame can be accessed and edited independently without decoding neighboring frames, making it exceptionally well-suited for video editing and applications requiring frame-accurate random access. MJPEG is commonly used in IP cameras, security surveillance systems, medical imaging, and industrial machine vision, where individual frame integrity and low processing latency outweigh the higher bandwidth requirements compared to modern interframe codecs. The format achieves typical compression ratios of 10:1 to 20:1 while maintaining good visual quality, though at significantly higher bit rates than temporal compression methods for equivalent quality. MJPEG streams can be delivered over HTTP, making them straightforward to implement in web-based monitoring applications, and the simplicity of the codec ensures reliable decoding even on resource-constrained embedded hardware.

xvid

Xvid is an open-source video codec that implements the MPEG-4 Part 2 Advanced Simple Profile standard, developed and maintained by volunteer programmers under the GNU GPL license. The project originated in 2001 as a fork of the OpenDivX codebase after DivX, Inc. closed the source of their codec, and the original name is DivX spelled backwards as a nod to this history. Xvid achieved widespread adoption in the early-to-mid 2000s as a free alternative to the commercial DivX codec, offering comparable or sometimes superior compression quality without any licensing costs. The codec excels at compressing full-length video into remarkably small files while preserving good visual quality, using techniques such as adaptive quantization, quarter-pixel motion compensation, global and local motion estimation, and custom quantization matrices. Xvid-encoded video is typically stored in AVI containers, though it can also be wrapped in MKV, MP4, and other formats. The codec gained certification for playback on many standalone DVD players and media devices that supported DivX playback, since both codecs share the underlying MPEG-4 ASP standard. Cross-platform availability covering Windows, Linux, macOS, and other operating systems, combined with a completely free and open-source nature, made Xvid a cornerstone of community-driven video encoding. While H.264 and newer codecs have largely replaced MPEG-4 ASP for new encoding, Xvid remains in use for compatibility with older hardware and in legacy media collections.

How to convert MJPEG to XVID

1

Select or drag&drop MJPEG video to convert it to the XVID format from your computer, iPhone or Android. Moreover, it is possible to choose it from your Google Drive or Dropbox account.

2

Now your video is uploaded and you can start the MJPEG to XVID conversion. If it is needed, change the output format to one of the 37 video formats supported. After that, you can add more videos for batch conversion.

3

If you want, you can customize such settings as resolution, quality, aspect ratio and others by clicking the gear icon. Apply them to all the video files if necessary and click the button "Convert" to process.

4

Once your video is converted and edited, you can download it to your Mac, PC or another device. If necessary, save the file to your Dropbox or Google Drive account.

Frequently Asked Questions

What is the benefit of converting MJPEG to XVID?

Since MJPEG compresses each frame independently, files are huge. Switching to XVID applies inter-frame compression for much smaller output.

How do I open an XVID file?

VLC, MPC-HC, and most software media players support XVID as an open-source MPEG-4 codec.

Is software installation required?

No installation needed. The MJPEG to XVID converter works entirely in your browser on any operating system or device.

Can I use this on a mobile device?

Absolutely. The converter works in any modern mobile browser — iPhone, Android, tablet — with the same features as on desktop.

Can I adjust resolution before converting?

Yes. Set the target resolution, bitrate, and codec in the settings panel before launching the MJPEG to XVID conversion.

Is registration required?

No. You can start converting immediately without creating an account. Registration is optional and unlocks additional features.
