How it works
How it works
Our thumbnail generator is trained on thousands of high-performing YouTube thumbnails.
Upload any image
JPG, PNG, GIF or WEBP, any starting size.
Choose fit or fill, never stretch
Fit keeps the whole image and pads it. Fill crops to ratio. Stretching distorts faces.
Download at the correct size
1280 x 720, 16:9, under 2MB, which is exactly what YouTube accepts.
Built for creators
What actually works
Built by creators, for creators. Every feature designed to help you grow.
Fit
keeps the whole image and adds background to fill the gap. Nothing is lost, but you get padding, which works if the background is a deliberate colour rather than plain white.
Fill
crops to the ratio and keeps the image edge to edge. You lose the edges, so it only works if your subject sits comfortably in the middle.
Designing at full size only
Your thumbnail is mostly seen around 168 pixels wide on a phone. Shrink it and look before you upload. If the text is unreadable, it is decoration.
Resizing last
Design at 1280 x 720 from the start. Resizing a finished design moves text you placed carefully.
Ignoring file weight
Heavy PNGs are the usual cause of failed uploads. JPG is fine for photographic thumbnails.
Frequently asked questions
Everything you need to know about our tools.
1280 x 720 pixels, a 16:9 ratio, under 2MB, in JPG, PNG, GIF or WEBP. Anything smaller gets scaled up by YouTube, which softens edges and makes text muddy at exactly the moment it needs to be sharp.
Too small and YouTube scales it up, losing sharpness. Wrong ratio and you get bars or a crop you did not choose. Over 2MB and it is rejected outright. Below 640 pixels wide it will not be accepted as a custom thumbnail at all.
Use fit or fill, never stretch. Fit keeps the whole image and adds background to fill the gap. Fill crops to the ratio and keeps the image edge to edge. Stretching distorts faces, which is instantly recognisable and reads as low effort.
Yes. Shorts use a vertical frame and the thumbnail is often the first frame of the video rather than an uploaded image. Do not simply crop the landscape version, because the safe zones differ and text near the top or bottom gets covered by interface elements.
Usually a heavy PNG. Switching to a high quality JPG normally brings it comfortably under 2MB with no visible loss, which is a better fix than dragging the quality slider down until it passes.
Yes, with a paid 1of10 plan. There is no export limit and no watermark. The free plan still gives you outlier search across 62 billion analysed YouTube views and three tracked channels, so you can test the research side before paying for anything.
Away from the bottom right corner. The video duration sits there in most YouTube surfaces and will cover whatever is underneath it. Keep faces, text and focal points clear of that area.
Design at 1280 x 720 from the first click. Resizing a finished design moves text you placed carefully and softens edges you sharpened, which is why so many thumbnails look slightly off after export.
