**Quick answer:** A YouTube thumbnail should be 1280 × 720 pixels (16:9, at least 640 pixels wide) and under 2 MB, as JPG, PNG or GIF, according to YouTube's help pages. This page crops or fits your image to 1280 × 720 and saves a high-quality JPG that is usually a few hundred KB, in your browser.

## How to use it

1. Choose the image: a frame from your video, a photo or a design.
2. Keep Video thumbnail, or pick Channel banner or Profile picture.
3. Keep Crop to fill, or choose a Fit option to show the whole picture.
4. Press Resize for YouTube and upload the JPG in YouTube Studio.

| Profile picture | 800 × 800 px | Shown as a circle, much smaller |

These follow YouTube's help pages at the time of writing. YouTube may ask you to verify your account before you can upload custom thumbnails; YouTube Studio tells you if so.

## Thumbnails that read at a glance

- **Think small**: most people see your thumbnail at a fraction of its size on a phone. Big faces and a few large words work; fine detail disappears.
- **Watch the corner**: YouTube puts the video length in the lower right corner, so keep text and faces out of it.
- **Start from a sharp frame**: grab one from your video with [Video to JPG](https://sharelargefilesfree.com/tools/video-to-jpg), then add a title with [Add text to image](https://sharelargefilesfree.com/tools/add-text-to-image).

## Under 2 MB without trying

A 1280 × 720 image saved as JPG at this page's quality is usually a few hundred KB, far under YouTube's 2 MB limit, even from a huge camera photo. If you switch **Save as** to PNG for a graphic with sharp text, check the size shown next to the result; a busy photo saved as PNG can go over 2 MB, and then [Compress PNG](https://sharelargefilesfree.com/tools/compress-png) or JPG is the fix.

For the channel banner, YouTube shows the full image only on TVs; phones and computers show a middle strip of about 1546 × 423 pixels at this size. Keep your channel name and logo inside it. Your images are resized on your device and never uploaded to us.
