A smaller image sequence for everyday sharing
JPG is useful when you need several review pictures without the larger files produced by PNG. This page starts with JPG selected in the workspace. Open a compatible video, choose a short range and set the capture interval. The resulting stills can be added to a document, storyboard or contact sheet in another application. Download the ZIP to keep the selected images together rather than saving each one individually.
Choose quality by looking at the subject
JPG is a lossy image format. It can soften small lettering or create artifacts around fine edges, especially when the source video is already compressed. After capturing, inspect one downloaded image at its actual size. If text, line art or editing flexibility matters more than file size, switch to PNG and capture again. Repeatedly saving an edited JPG can introduce more loss, so keep a suitable master for any important design work.
Keep file names and sampling times useful
The archive uses numbered files with requested timestamps, such as frame_0001_2-000s.jpg for a first capture at two seconds. The timestamp helps you return to the source; it is not an exact source-frame identifier. The selected end is excluded from a batch. Start with a one-second interval, then make it smaller for brief events or larger for a scene overview. Use shorter segments when the 120-frame or 96 MB gallery limit would be exceeded.
Start with a short test
- Choose a compatible local video and wait for a playable preview.
- Capture one useful moment, or select a short range and interval.
- Compare the actual subject, then download an image or gallery ZIP.
The workspace accepts sources up to 2 GB and 8.3 million decoded pixels per frame. A gallery holds up to 120 images or 96 MB. Seeking depends on the browser and source timing. Keep the source, use media you have permission to process, and check a small output before starting a larger batch.
Questions for this workflow
Can I switch the sequence to PNG or WebP?
Yes. Choose another image format before capture. The archive uses the actual exported format.
Does JPG reduce the original video resolution?
The captured image retains decoded dimensions. JPG changes image compression, not the width and height of the capture.
