imgmov Last Frame Extractor is a free browser utility for video editors, creators and tutorial authors who need a still image from the end of a clip. Open a local video or try the built-in sample, inspect the final frame and a nearby earlier frame, then download a PNG. Frame extraction runs locally on your device and the tested workflow needs no account. It is useful for checking an ending composition or preparing a reference still for a follow-on clip. Video playback depends on your browser and codec support. This listing covers the standalone frame-extraction utility.
