Thumbnail Resizer
Resize any image to YouTube’s perfect 1280×720 size. Drag to reposition the crop, fine-tune brightness and contrast, auto-compress under 2 MB — all in your browser.
The Right Size
YouTube recommends 1280×720 pixels (16:9), at least 640 pixels wide, under 2 MB, in JPG, PNG or WebP format. The “Fit under 2 MB” button guarantees the limit.
100% Private
Your image never leaves your device. All resizing, cropping and adjustments happen in your browser using the canvas API — nothing is uploaded to any server.
Full Control
Drag the crop into position, zoom in on the subject, fix brightness and contrast, rotate or flip — then export in exactly the size and format you need.
