- Batch stills → same crop preset across episode series.
- Shorts still → verify legibility at phone notification size.

FAQ
Frequently asked questions
What is the YouTube thumbnail size?
1280 × 720 pixels at a 16:9 ratio, with a minimum width of 640 pixels. This tool center-crops and exports JPG or PNG at that size. YouTube also accepts larger 16:9 files (up to 3840 × 2160) when you have a high-resolution source.
What size should a YouTube channel banner be?
2560 × 1440 pixels, with important text and logos kept inside the safe area (about 1235 × 338 px per YouTube Help; some guides cite ~1546 × 423 px). Maximum file size is 6 MB.
How do I enlarge a thumbnail?
Upload the image and resize it to 1280 × 720 with the crop tool below. For best quality, start from a larger source image because enlarging a small one can look blurry.
What is the max file size for a YouTube thumbnail?
2 MB when uploading from mobile, in JPG or PNG format. Desktop uploads in YouTube Studio allow up to 50 MB. Export JPEG if you need a smaller file.
Are my images uploaded?
