FrameKeeper — Video Frame Extractor

Grab the frame you want — without ever pausing. FrameKeeper lets you capture a still frame from a video while it keeps playing. Watch fullscreen, press a shortcut, and FrameKeeper captures a short burst around that moment, automatically keeping the sharpest frame. How it works: 1. Open a supported YouTube or Bilibili video. 2. Press Alt + Shift + S while the video is playing. 3. Open the FrameKeeper tray to review, zoom, remove, or export your frames. Features: • Capture video frames without pausing playback • Automatically keep the sharpest frame from a short burst • Review captured frames in an in-page tray • Zoom in before exporting • Export individual images or the tray as a ZIP archive • Supports PNG, JPEG, and WebP • Adjustable image quality and burst count • Dark, light, and system themes • Interface available in 10 languages • All frame processing happens locally in your browser Supported sites: • YouTube • Bilibili Private by design: FrameKeeper does not collect, upload, sell, or share captured frames, browsing activity, or personal information. Captured images and extension settings remain on your device. FrameKeeper captures individual still images from the video currently playing. It does not save or reproduce the source video and does not bypass protected playback. FrameKeeper is an independent product and is not affiliated with YouTube or Bilibili.
