About Video Thumbnail Extractor
Video Thumbnail Extractor lets you capture still images from a video quickly and precisely. Move to an exact time, save multiple thumbnail candidates, or automatically collect frames at fixed intervals or evenly across the full video.
Common use cases
Review footage quickly
Extract multiple evenly spaced frames to scan the contents of a clip without watching it in full.
Save reference stills
Export exact moments from a video as JPG or PNG images.
How it works
1
The browser opens the video and reads its duration.
2
You select specific timestamps or request automatically spaced capture points.
3
Frames at those times are rendered to images and prepared for download.
Privacy & file handling
Frame extraction runs locally
The source video is decoded in the browser and selected frames are exported without requiring the clip to be uploaded to Zavilo.
Limitations and important notes
- A captured frame can be blurry if the selected moment contains motion.
- Seeking accuracy depends on browser decoding and the video's keyframe structure.
- Extracted images contain only one frame and do not preserve audio or motion context.

Frequently asked questions
Which video formats can I use?
MP4, WebM and MOV are supported. Some files may use video codecs that are not supported.
Why does a MOV or MP4 file sometimes fail to open?
A video file can use a codec that is not supported even when its extension is MP4 or MOV.
Can I extract many frames at once?
Yes. Add frames manually, extract by a time interval, or distribute a chosen number of frames evenly across the video. Automatic extraction is limited to 50 frames.
