All my photos are square from Instagram. Now I can turn them into YouTube thumbnails without the weird cropping. AI extends the background.

The smart cropping is actually smart. It keeps my face visible instead of cutting off my head like other tools do.

Batch resizing 50 thumbnails for my old videos took maybe 20 minutes. Would've been hours doing it manually.

FAQ
Resize Youtube Thumbnail Online FAQ
What if my image is smaller than 1280x720?
Tool will upscale it, but quality suffers. Best to start with images at least 1280x720 or larger.
Can I resize square images for YouTube?
Yes. Square images get cropped to 16:9 or you can add fill color on sides. Your choice.
What about portrait orientation photos?
Same options. Crop to 16:9 focusing on key area, or add fill on sides.
Does resizing hurt quality?
Downsizing keeps quality. Upsizing loses some. Start with larger images when possible.
Can I resize multiple thumbnails at once?
Yes. Batch upload supported. Set crop rules and process multiple images together.
What is YouTube recommended thumbnail size?
1280x720 pixels at 16:9 aspect ratio. Under 2MB file size. This tool exports exactly that.
