Need help?Convert Image to MJPEG Online
This tool wraps a still picture into an MJPEG (Motion JPEG) video that holds your image on screen for a duration you set. There is no motion and no audio — a single image becomes a silent clip of one repeated frame, and several images become a silent slideshow. It accepts 36 input formats (JPG, PNG, WebP, HEIC, TIFF, BMP, GIF, AVIF, PSD, EPS, ICO, and RAW camera files like CR2, CR3, NEF, ARW, and DNG). MJPEG stores every frame as a complete, independent JPEG with no inter-frame compression, so reach for it only when a tool or workflow specifically expects Motion JPEG — otherwise the file will be large for what it shows.
How to Convert Image to MJPEG
- Upload Your Image File: Drag and drop your image onto the page or click "Add Files". You can add several images at once across any of the 36 supported formats.
- Set the Duration: Open Advanced Options and pick a value under "Duration" (default 5 seconds per frame) — presets run from a single frame (1/60s up to 0.5s) through 1 to 10 seconds per frame, which sets how long each image is held.
- Choose Merge Strategy and Quality: Under "Merge strategy" pick "Merge images" to chain several pictures into one slideshow clip or "Video per image" for a separate file each; leave "Quality Preset" on "Very High (Recommended)" for near-source frames, and use "Background Color" (default Black) to fill any letterbox area.
- Convert and Download: Click "Convert" and download your MJPEG. No sign-up, no watermark.
Image to MJPEG vs Image to MP4 — Which Output to Pick
| Property | MJPEG (this tool) | MP4 / H.264 |
|---|---|---|
| Compression | Intraframe only — every frame is a full JPEG | Interframe — predicts between frames |
| Typical efficiency | ~1:20 or lower | ~1:50 or better |
| File size for stills | Large (a JPEG per frame) | Small |
| Audio | Silent (image source has no audio) | Silent here too, but the codec supports audio |
| Frame access | Any frame decodes on its own | Frames depend on neighbours |
| Best for | Frame-accurate editing, capture/webcam rigs, machine vision | Sharing, social, phones, anything you just want to watch |

Frequently Asked Questions
Why is my Image to MJPEG file so large?
Because MJPEG has no inter-frame compression — every frame is stored as a complete, standalone JPEG. For one still image that means the same picture is re-encoded for every frame of the clip, so even a short MJPEG is far bigger than the source image and much larger than an equivalent MP4. Modern interframe formats reach compression ratios around 1:50 or better, while M-JPEG sits near 1:20 or lower. If you want a small, shareable file, convert your image to MP4 instead, or convert the finished clip with MJPEG to MP4.
Does the MJPEG clip have any motion or sound?
No. A still image is one frame, so the clip simply holds that frame for the duration you choose — there is no animation. The output is also silent: an image source has no audio to encode, and MJPEG itself carries no sound (audio, when present in a video, is a property of the container such as AVI or MOV, never the Motion JPEG stream). Uploading several images produces a silent slideshow, not an audio-backed video.
Which image formats can I convert to MJPEG?
36 input formats: JPG/JPEG/JFIF, PNG, WebP, HEIC/HEIF, AVIF, TIFF/TIF, BMP, GIF, ICO, EPS, PSD, PUB, XCF, ODD, ODG, PPM, and RAW files from major camera brands — Canon (CR2, CR3, CRW), Nikon (NEF), Sony (ARW), Adobe (DNG), Olympus (ORF), Panasonic (RW2), Fujifilm (RAF), Pentax (PEF), Sigma (X3F), Minolta (MRW), Hasselblad (3FR), Kodak (DCR), Epson (ERF), and Leaf (MOS). You can mix formats in a single batch.
Will converting to MJPEG lose image quality?
Each frame is re-encoded as a JPEG, so leaving "Quality Preset" on "Very High (Recommended)" keeps it visually close to your source. In our testing, a single 1920x1080 image at the Very High preset produced a clip whose per-frame quality was essentially indistinguishable from the original at normal viewing distance; lower presets visibly soften fine detail in exchange for a smaller file.
How are my uploaded files handled?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, and nothing is shared or made public. The only practical limit on a big job is upload size and time, not anything on your device.
