How to make a YouTube thumbnail in CapCut
Open CapCut's YouTube thumbnail canvas at 1280 × 720, add one subject and a short line, export a still image (not a video), and upload it in YouTube Studio.
4 min read ThumbnailsYouTubeGuidesStudioCapCut is where a lot of people already edit. You can make the thumbnail there too. CapCut cannot put it on your video for you. You export a still image, then upload it yourself in YouTube Studio.
This post sticks to the CapCut clicks. If you want the thinking behind a good thumbnail first, [how to make a YouTube thumbnail](/blog/how-to-make-a-youtube-thumbnail) covers it. Prefer Canva? That path is [how to make a YouTube thumbnail in Canva](/blog/how-to-make-a-youtube-thumbnail-in-canva).
Start from CapCut's YouTube thumbnail size
Open [CapCut Online](https://www.capcut.com/). In the workspace, under **Social media**, pick **YouTube**, then **YouTube thumbnail**. That canvas opens at **1280 × 720 px**, which is 16:9.
You can also enter **1280** and **720** under **Custom size**, then click **Create**.
That's the practical size to start from. The full spec, including YouTube's 4K recommendation, lives in [YouTube thumbnail size](/blog/youtube-thumbnail-size).

Pick a template or start blank
CapCut Online has templates made for YouTube thumbnails. Skim them and pick one that matches your channel, or start from the blank **YouTube thumbnail** canvas.
A template is a fine starting layout. Swap the photo, the words, and usually the colors. If you keep most of it, your thumbnail looks like every other channel that grabbed the same one.
Starting blank is better when your channel already has a look. It also makes it easier to stick to one subject and one line.
Add one subject
Click **Upload** and bring in your photo. A face or one clear object works best. Drag it onto the page and make it big.
One subject reads at phone size. Two or three fight each other. The longer reason is in [how to make a YouTube thumbnail](/blog/how-to-make-a-youtube-thumbnail).
Add a 3 to 5 word line
Open the **Text** tab and add one short line. Three to five words is plenty. Say something the title doesn't, so the two work together instead of repeating each other.
Make the text big and bold, with strong contrast against the background. Keep it and your subject out of the bottom-right corner, because YouTube puts the video length there. [YouTube thumbnail safe zones](/blog/youtube-thumbnail-safe-zones) shows everything YouTube lays over the image.
Shapes and stickers are optional. Use them only when they help the one idea land.
Export a still image, not a video
This is the trap. You need a JPG or PNG for Studio, not a clip.
On CapCut Online, click **Export** at the top right. Choose a resolution that matches **1280 × 720** when you can, then **Download** the image.
On CapCut Desktop, if you built the thumbnail on a video timeline, pause on the frame you want. Open the menu near the Player and choose **Export still frames**. Pick **JPEG** or **PNG**, set the destination, and export. That dialog is separate from the video **Export** button.
YouTube takes JPG or PNG. The size limit is 2 MB when you upload from a phone and up to 50 MB from desktop YouTube Studio. The rest of the spec is in [YouTube thumbnail size](/blog/youtube-thumbnail-size) and [YouTube thumbnail file size](/blog/youtube-thumbnail-file-size). If your file is too big for a phone upload, [how to compress a YouTube thumbnail](/blog/how-to-compress-youtube-thumbnail) gets it down without making it mushy.
Upload it in YouTube Studio
Sign in to YouTube Studio and select **Content** in the left menu, then click the video's title or thumbnail to open **Details**. Under **Thumbnail**, click **Upload file**, pick your JPG or PNG, and click **SAVE**.
Don't see **Upload file**? Your channel probably needs phone verification first, and [how to enable custom YouTube thumbnails](/blog/how-to-enable-custom-youtube-thumbnails) walks through it. To swap a thumbnail later, see [how to change a YouTube thumbnail](/blog/how-to-change-youtube-thumbnail).
Soft second pass
CapCut gets you a file. When you want a second look before you publish, run the still through Thumbly Score or open it in Studio and check how it reads at feed size. [How to use Thumbly Score](/blog/how-to-use-thumbly-score) explains the numbers.
