FAQ
What is a keyframe (I-frame)?
A keyframe is a complete image within a video sequence. Other frames only store the changes from the keyframe to save space. Keyframes represent the best quality images in the video.
Why use this instead of taking a screenshot?
Screenshots capture exactly what is on screen, which might be a compressed P-frame or B-frame. This tool extracts the raw reference image, ensuring maximum clarity.
What image formats are supported?
