About YouTube Thumbnail Maker — Free Online Tool
YouTube Thumbnail Maker scales an image to the 1280 × 720 frame this tool is coded to produce and encodes it as a JPEG at the quality you choose.
The dimensions are not adjustable here; what you control is the fit, the quality and the size ceiling, which starts at the 2 MB that YouTube refuses a thumbnail above. When a budget is set the encoder bisects the JPEG quality until the file fits under it, and tells you the quality it settled on; set the ceiling to zero and the weight simply follows your quality setting instead. Nothing is composited over the picture — no outline, caption or glow is added, so what you get back is your own frame at thumbnail dimensions and nothing else. The panel reports the size before and after, so if the JPEG is heavier than you want, the quality slider is the lever and you can see what each step down buys.
The frame is resized by your own browser from the file you picked. It is never uploaded here, and it is not sent to YouTube; opening Studio and attaching the download stays a separate step you do yourself.
Getting a screenshot or video export to exact thumbnail dimensions, reshaping a vertical photo so it is not reduced to a strip in the player, and bringing down the weight of a large PNG export before it goes up with a video.
