ALTools
Video Screenshot
Capture a still frame from video, or stitch multiple frames into one image. Processed in your browser.
How to use this tool — step-by-step guideHow Video Screenshots Work
Upload a video and scrub to the exact moment you need. ALTools captures frames on your device—no upload to a server and no account required.
Move along the timeline or enter a timestamp, preview the frame, then grab a still image. Decoding and capture run entirely in the browser so you see the result before downloading.
Grab thumbnails from long recordings, document a UI state, save a quote slide from a talk, or pull a crisp still for social posts and bug reports.
Screenshots stay local, so confidential demos and unreleased footage never travel off your machine. Re-scrub and re-capture as often as you need without re-uploading.
Download the frame as PNG or JPEG—a sharp still ready for docs, tickets, presentations, or sharing.
