Need help?How to Convert PNG to MJPEG Online
- Upload Your PNG Files — Drag and drop or select one or more PNG images.
- Choose Merge Strategy — Select Merge images to combine all PNG files into a single MJPEG video, or Video per image to create a separate video for each image.
- Set Image Duration — Choose how long each image displays: from 1/60s (single frame at 60fps) to 10 seconds per frame.
- Choose a Quality Preset — Select from Highest, Very High (Recommended), High, Medium, Low, Very Low, or Lowest.
- Set Resolution (Optional) — Keep original, pick a preset (4320p down to 144p), or enter exact width × height.
- Convert & Download — Click Convert and download your MJPEG files.
The video codec defaults to MJPEG (Motion JPEG) for MJPEG output. Under Advanced settings, the audio codec and background color can be customized.
Why Convert PNG to MJPEG?
PNG is a lossless image format. MJPEG (Motion JPEG) is a video format where each frame is compressed as a separate JPEG image — no inter-frame compression. This makes MJPEG ideal for frame-by-frame editing, CCTV/security systems, older digital cameras, and industrial video applications where individual frame access is critical. Converting PNG images to MJPEG creates video content compatible with these specialized systems.
PNG vs MJPEG
| Feature | PNG (image) | MJPEG (video output) |
|---|---|---|
| Type | Still image (lossless) | Video (per-frame JPEG) |
| Compression | Lossless | Lossy (per frame) |
| Inter-frame compression | N/A | ❌ (each frame independent) |
| Frame-by-frame editing | N/A | ✅ Easy |
| CCTV / security systems | ❌ | ✅ Standard format |
| File size | Moderate | Large (no inter-frame) |
| Webcam compatibility | ❌ | ✅ |
Use Cases
- CCTV and security — MJPEG is a standard format for security cameras and DVR systems. Create MJPEG video from PNG images for security system integration.
- Industrial video — Manufacturing inspection systems and industrial cameras often use MJPEG for reliable frame-by-frame capture.
- Frame-accurate editing — MJPEG allows editing any individual frame without re-encoding adjacent frames, unlike H.264 or H.265.
- Webcam simulation — Some software expects MJPEG input from webcam streams. Convert PNG images to MJPEG for virtual camera feeds.
What is MJPEG?
MJPEG (Motion JPEG) is a video format where each frame is a separate JPEG image. Unlike modern codecs (H.264, H.265) that use inter-frame compression, MJPEG compresses each frame independently. This results in larger files but allows easy frame-by-frame access.
Why are MJPEG files so large?
MJPEG does not use inter-frame compression — each frame is a complete JPEG image. Modern codecs like H.264 store only the differences between frames, achieving much smaller files. MJPEG trades file size for frame independence.
How long will each image display?
You control this with the Image Duration setting. Options range from 1/60s (a single frame) to 10 seconds per image.
Can I merge multiple PNG images into one video?
Yes. Select "Merge images" under Merge Strategy. All uploaded PNG files are combined into a single MJPEG video in upload order.
Can I set a background color?
Yes. Under Background Color, choose from Black (default), White, and other colors. This fills the space around images that don't match the output resolution.
