FAQ
JPG or PNG?
JPG for photos and covers (smaller), PNG for screenshots with text or sharp edges (lossless).
Which moment should I pick?
For YouTube covers, a frame with a face or strong contrast works best — scrub the source video first, then grab that second.
Can I grab several frames?
Run the tool a few times at different seconds — or claim the video into your library and use the editor's frame export.
