TIFF to MJPEG Converter

How to Convert TIFF to MJPEG Online

1. Upload Your TIFF Files: Drag and drop or click "+ Add Files" to select one or many .tif / .tiff images. For a multi-page TIFF or a numbered sequence (frame_0001.tif, frame_0002.tif, ...), upload them all — they will be ordered by filename.
2. Set Merge Strategy and Image Duration: Pick "Merge images" to build a single MJPEG video from the whole sequence, or "Video per image" to render one short clip per TIFF. Then set Image Duration — choose 1/30s or 1/24s for cinematic timelapse playback, 1/60s for slow-motion analysis, or 1–10 seconds per frame for slideshow pacing.
3. Tune Background Color, Quality Preset, and Resolution (Optional): Background Color defaults to White for transparent-TIFF padding (switch to Black for a dark matte, Green for chroma key). Quality Preset defaults to Very High; drop to High or Medium to shrink the file. Resolution defaults to 768p — pick a fixed preset like 1920x1080 / 3840x2160 or scale by percentage to match your timeline.
4. Convert and Download: Click Convert. Output is MJPEG (Motion JPEG) in the .mjpeg raw stream container, ready to drop into FFmpeg, OpenCV, OBS Studio, or any pipeline that expects per-frame JPEG access.

Why Convert TIFF to MJPEG?

TIFF is a lossless raster container favoured by scanners, microscopes, satellite sensors, and DSLRs working in 16-bit mode — every pixel is preserved, but a single 4K frame can run 30–80 MB, which makes a thousand-frame capture unmanageable to scrub through. MJPEG (Motion JPEG, standardised in RFC 2435 for RTP transport) compresses each frame as an independent JPEG, typically reaching 1:20 compression while keeping every frame randomly accessible. That intra-frame design — no P-frames, no B-frames, no GOP — is exactly what scientific, surveillance, and editing workflows want when they need to seek to any single frame without decoding a dependency chain.

• Microscopy and timelapse playback — Time-lapse sequences exported as TIFF stacks from Leica LAS X, Nikon NIS-Elements, or Zeiss ZEN often hit hundreds of GB. MJPEG keeps every frame quality-independent so cell division or crystal growth can be scrubbed frame-by-frame in ImageJ/Fiji or Imaris without GOP artefacts.
• Photogrammetry and drone surveys — Sequences from Pix4D, RealityCapture, or Agisoft Metashape are often archived as TIFF; an MJPEG proxy is faster to preview and review on disk than 16-bit linear TIFFs.
• Industrial machine-vision review — Cognex, Basler, and FLIR cameras stream MJPEG natively; converting TIFF inspection frames to MJPEG keeps the archive in the same codec the line camera produced.
• Security and forensic chain-of-custody — Each MJPEG frame stands alone as a JPEG, which makes per-frame export and SHA-hashing for evidence simpler than slicing an H.264 GOP.
• Non-linear editing proxies — DaVinci Resolve, Premiere Pro, and Final Cut Pro all decode MJPEG efficiently for scrubbing. A 4K MJPEG proxy is heavier on disk than H.264 but lighter on CPU because each frame decodes independently.
• Slideshow-to-video conversion — Drop a folder of photo-scanned TIFFs in, set 3–5 seconds per frame, and you have a slideshow MJPEG that any browser or VLC can play without an extra container.

Frequently Asked Questions

Why is the output .mjpeg instead of .avi or .mov?

The MJPEG conversion produces a raw Motion JPEG elementary stream (.mjpeg), which is the codec on its own without a container. FFmpeg, VLC, OBS, OpenCV, and most NLEs read it directly. If you need MJPEG wrapped in AVI or QuickTime — common for older surveillance recorders or some scientific software — convert to AVI or MOV with the MJPEG codec selected; xconvert exposes that selection on the convert-jpg-to-mjpeg and related video pages.

Will a multi-page TIFF be treated as a frame sequence?

Yes. Multi-page TIFFs (often produced by scanners and microscopes) are decoded page-by-page and each page becomes one MJPEG frame in the order it appears in the file. If you have separate single-page TIFFs instead, upload them all in one batch and they are ordered alphabetically by filename — name them with zero-padded counters (frame_0001.tif, frame_0002.tif) to keep the order stable past 1000 files.

How much smaller will the MJPEG be than the source TIFF stack?

Expect roughly 1:20 to 1:30 compression versus uncompressed 8-bit TIFF. A folder of 500 uncompressed 1080p TIFFs at ~6 MB each (3 GB total) typically lands around 100–150 MB as MJPEG at the Very High preset. 16-bit TIFFs shrink more dramatically because MJPEG is 8-bit per channel — plan for that quantisation if your downstream tool relies on 16-bit precision.

Does MJPEG keep the 16-bit precision of my scientific TIFFs?

No. JPEG (and therefore MJPEG) is 8-bit per channel with 4:2:0 or 4:2:2 chroma. If your analysis requires the full 16-bit linear values from a microscope or radiometric sensor, keep the TIFF master and use MJPEG only as a preview/proxy. For lossy-but-higher-bit-depth proxies, H.265 10-bit or ProRes 422 HQ are better choices.

Can I play the resulting MJPEG file in a regular browser or video player?

Yes for VLC, mpv, QuickTime, Windows Media Player, and any FFmpeg-based player. Browsers (Chrome, Firefox, Edge, Safari) historically played MJPEG natively as multipart/x-mixed-replace streams but do not always decode a standalone .mjpeg file from <video> — for guaranteed browser playback, convert to MP4/H.264 via TIFF to MP4 or TIFF to MOV instead.

What frame rate does "Image Duration" actually set?

Image Duration is per-frame display time and the output frame rate is its reciprocal. 1/30s per frame is 30 fps; 1/24s is 24 fps; 0.2 seconds per frame is 5 fps; 5 seconds per frame is 0.2 fps. Pick the value that matches your downstream tool — 24/25/30 fps for editing, 60 fps for slow-motion review, 1–5 second values for slideshows.

Why does the file still look "blocky" compared to my original TIFF?

JPEG compression introduces 8x8 DCT-block artefacts around hard edges and fine textures (text, scan lines, fluorescence speckle). The Very High preset minimises this but cannot eliminate it. If you need pixel-exact frames for image analysis, keep working from the TIFF stack and use MJPEG only for human review.

My TIFFs are different sizes — what happens to the output?

The first file's dimensions set the canvas. Smaller frames are padded with the Background Color (default White; pick Black for a dark matte or set a green/blue for keying). Larger frames are scaled down to fit. To force a specific output resolution regardless of source, pick a Fixed Resolutions preset (1920x1080, 3840x2160) or enter custom width/height in the Resolution control.

Can I add audio to the MJPEG?

Not in this image-to-video flow — when the source is images there is no audio track. If you need narration or music, convert TIFF to MP4 first, then mux a soundtrack with FFmpeg (ffmpeg -i video.mjpeg -i audio.mp3 -c copy out.mov) or your NLE. MJPEG in an AVI or MOV container does support a PCM or MP3 audio track when paired with a separate audio source.
