Veelgestelde Vragen
What is the best thumbnail size for YouTube?
YouTube recommends 1280x720 (16:9) with minimum 640px width, under 2 MB. This tool outputs full-resolution frames — use 1080p+ source video for best results.
Auto vs manual frame selection?
Auto mode extracts well-distributed frames with good exposure and sharpness. Manual mode lets you scrub to any timestamp. Best approach: grab auto frames, then manually pick the winner.
What resolution are the thumbnails?
Full source resolution — 1080p video gives 1920x1080 thumbnails, 4K gives 3840x2160. Output is PNG for maximum quality; convert to JPG later if needed.
How many frames can I extract?
As many as you need. Auto mode generates a set across the video duration. Manual mode captures one at a time from any point. All download as individual PNG files.
