Extract Video Frames saves still images from a local video at the interval you choose. The output is packaged as a ZIP with sequential frame names so the images are easy to review, rename, or import elsewhere.
Frame extraction can grow quickly. A one-hour video at one frame per second would create thousands of files, so Convertful includes an interval and maximum-frame setting to keep the browser workload practical.
JPG is the right default for most video stills because it keeps the ZIP smaller. PNG is useful for UI demos, slides, or source video with sharp text where compression artifacts are more noticeable.
Convertful saves the selected frames into a ZIP file, with sequential names such as frame_0001.jpg or frame_0001.png.
Yes. Set the interval in seconds and a maximum frame count. Those controls keep long videos from creating thousands of images in one browser tab.
No. FFmpeg.wasm decodes the video and creates the images locally. The ZIP is assembled in your browser and is not uploaded.
JPG is smaller and good for video stills. PNG is lossless and better when you need sharper UI captures or want to avoid JPEG artifacts.
The browser has to decode the video, store frame images, and package a ZIP. Very long or high-resolution videos can exceed memory limits.
