How YouTube Thumbnail Resizer works
Resize and crop images to YouTube thumbnail size, including 1280×720 and 16:9. Prepare a thumbnail and reduce file size before upload.
- What you provide
- An image to fit into a 16:9 YouTube thumbnail frame.
- What AG File Tools returns
- A 1280 × 720 image when the YouTube preset is selected.
- Practical limit
- AG File Tools resizes and crops the artwork; it does not design thumbnail text or guarantee platform approval.
