About this tool
The recommended YouTube thumbnail size is 1280×720 pixels (aspect ratio 16:9). “Fill & crop” scales your photo to cover the whole frame and trims the edges; “Fit with background” shows the entire photo with coloured bars, which is useful for product shots and graphics you don’t want cropped.
FAQ
Are my images uploaded to a server?
No. Images are processed with the HTML canvas API inside your browser. They never leave your device, which makes PixSquish safe for personal photos and confidential screenshots.
Which formats are supported?
Anything your browser can open: JPG/JPEG, PNG, WebP, GIF (first frame), BMP, SVG and, in most modern browsers, AVIF. Output can be JPG, PNG or WebP.
What size is a YouTube thumbnail?
1280×720 pixels is the recommended size. Uploading at exactly this size avoids the platform recompressing or cropping your image unexpectedly.
