Supports: GIF
GIF is limited to 256 colors and uses LZW compression, producing large files for anything beyond simple graphics. MJPEG (Motion JPEG) compresses each frame independently as a JPEG image, offering better color reproduction (16.7 million colors) and more predictable file sizes. Converting GIF to MJPEG is useful when you need to import animations into video editing software, embed them in systems that don't support GIF playback, or use them in industrial/embedded applications where MJPEG is the standard format.
MJPEG's per-frame compression makes it ideal for video editing because every frame is a complete image — there's no inter-frame dependency, so you can cut at any point without artifacts. This is why MJPEG remains popular in professional NLE (non-linear editing) workflows, security camera systems, and embedded devices.
| Feature | GIF | MJPEG |
|---|---|---|
| Colors | 256 max | 16.7 million (24-bit) |
| Compression | LZW (lossless) | JPEG (lossy per-frame) |
| Frame editing | Difficult | Cut at any frame |
| Transparency | Binary (on/off) | No |
| Audio | No | No (video only) |
| Browser playback | Universal | Limited |
| NLE compatibility | Poor | Excellent |
| Common use | Web animations | Editing, security, industrial |
MJPEG (Motion JPEG) is used in video editing workflows (every frame is independently editable), security camera systems (IP cameras often stream MJPEG), industrial machine vision, medical imaging, and embedded systems. It's valued for its per-frame independence — no inter-frame compression means any frame can be accessed instantly.
Yes. Upload multiple GIF files and select "Merge images" under "Merge strategy." The GIFs play in sequence as a single MJPEG video. Set the duration per image to control playback speed.
For animated GIFs being converted to video, try matching the original GIF's frame timing. For static GIFs being merged into a slideshow, 2–5 seconds per image works well. For fast-paced content, use 0.5–1 second.
No. MJPEG is a video-only format. If you need audio, consider converting to MP4 or WebM instead, which support both video and audio tracks.
The color depth improves from 256 colors (GIF) to 16.7 million colors (MJPEG), but MJPEG uses lossy JPEG compression per frame. For GIFs with limited colors (logos, pixel art), the visual difference is minimal. For photographic GIFs, MJPEG can actually look better due to the expanded color palette.
"Keep original" preserves the GIF's native dimensions. If your GIF is small (e.g., 320×240), you can upscale to a preset like 720p, though this won't add detail. For web-sourced GIFs, keeping original resolution is usually best.
