Sometimes you do not want a still – you want every still, in order. Converting video to an image sequence gives you a numbered set of frames (frame_00001, frame_00002, …) that drops straight into animation tools, analysis pipelines and training datasets.
The converter above produces exactly that: frames sampled at a fixed interval, sequentially numbered, packed into a single ZIP. It runs locally in your browser via FFmpeg WebAssembly, so a ten-minute research recording never has to touch a server.

Animators import frame sequences for reference, rotoscoping and cleanup. A numbered JPG or PNG sequence loads into any compositing or drawing tool as-is.
Object detection and pose estimation models train on labeled frames. Extract at a fixed FPS and the sequence order doubles as your annotation timeline.
Microscopy, fluid tests, production-line monitoring – researchers need every frame at a known interval, with numbering that survives sorting and scripting.
A swing, a sprint, a lift: exported as a sequence at 10–30 FPS, the movement can be stepped through frame by frame or overlaid for comparison.
Speed a long recording up by sampling at low FPS, or rebuild motion from stills – an image sequence is the raw material for both.
Drop an MP4, MOV, AVI, WEBM or MKV file into the tool above. Large files are fine – decoding happens on your device, so there is no upload queue and no size-based rejection.
Enable Time Range to convert only the section you care about. The dual slider shows the exact start and end times and stays in sync with the player.
Choose By FPS for a fixed interval (1–30 FPS), or By Total Count when you need exactly N frames. The estimate next to the settings shows how many images you will get.
Click Extract Frames and watch the progress bar. Every frame is decoded in order and numbered sequentially – the numbering is stable across reruns with the same settings.
Click Download All as ZIP to get the complete image sequence in a single archive – ready to drop into your animation tool, dataset folder or analysis script.
Upload the video above, set an FPS (or a total frame count), and click Extract Frames. You get sequentially numbered images – frame_00001.jpg, frame_00002.jpg and so on – downloadable individually or as one ZIP.
Match the purpose: 1 FPS for summaries, 5–15 FPS for motion analysis, and the video’s native rate (usually 24–30) when every frame matters, such as rotoscoping or measurement work.
PNG if the frames feed an editing or measurement pipeline – it is lossless. JPG if the sequence is for reference, review or training data where small files matter more; use 90%+ quality for a good balance.
No hard limit – the extractor runs locally, so the practical limit is your disk space and patience, not a server quota. Use Time Range and a sensible FPS to keep very long videos manageable.
