About MJPEG
MJPEG
MJPEG (Motion JPEG) is a video format in which each individual frame is compressed as a separate JPEG image. Because each frame is independent, MJPEG supports precise frame-accurate editing and is widely used in IP cameras, webcams, surveillance systems, and non-linear video editing workflows.

Frequently Asked Questions
What is an MJPEG file?▼
MJPEG (Motion JPEG) is a video format where every frame is a separate JPEG image. It is used by webcams, IP cameras, and some cameras because each frame is independent and easy to capture.
Why convert MJPEG to MP4?▼
MJPEG files are large because each frame compresses independently. Converting to a modern inter-frame codec like H.264 MP4 gives similar visual quality at a fraction of the size.
Is MJPEG still used?▼
Yes — mainly in IP cameras, webcams, and some capture devices that benefit from per-frame simplicity. For playback and sharing, MP4 or WebM are far more efficient.
Does converting MJPEG lose quality?▼
Re-encoding to H.264 at a sufficient bitrate preserves visible quality, while the much smaller file is far easier to store and share.
Are my recordings uploaded when converting?▼
No — conversion happens locally in your browser.
