How to change a YouTube Shorts thumbnail (and make a good one)

Yes, in two ways. Until July 2026, the only choice was a frame of the Short itself. On July 24, 2026, YouTube announced that creators in its Partner Program can upload custom thumbnails for Shorts, and said it will expand this to more creators over time. YouTube's help center adds that your account must be verified to use it. Here's what you can do where:

YouTube also now suggests three frames to choose from for Shorts on a computer, as it does for long videos. And the thumbnail you choose for a Short follows the same rules as any other: it must follow YouTube's Community Guidelines.

On a computer, in a browser:

1. Sign in to YouTube Studio (studio.youtube.com).
2. Open Content in the menu on the left, then the Shorts tab at the top.
3. Open the Short you want to change, with the edit (pencil) icon.
4. Under Thumbnail, click Upload file and choose your image.
5. Click Save. YouTube says the new thumbnail can take a while to appear.

No Upload file button? Check these, in order:

• Verify your account. YouTube asks for a phone number and sends a code; verifying unlocks custom thumbnails, among other features.
• It may not have reached you yet. The upload started with Partner Program creators in July 2026 and is rolling out to others over time.
• The daily limit. Channels can upload only so many custom thumbnails a day. If you see “Daily custom thumbnail limit reached”, try again in 24 hours.
• Strikes. Community Guidelines strikes cut how many custom thumbnails you can upload, and repeated thumbnail violations can take the feature away for 30 days.

On a phone, you choose a frame of the Short rather than an image of your own. You can do it while you post it, or later. YouTube's steps, for Android and iPhone:

While you upload the Short:

1. Tap Create, then Short, record or add your video, and fill in its details.
2. On the final upload screen, tap Edit on the thumbnail.
3. Pick the frame you want. You can add text and apply filters to it.
4. Tap Done.

After it's posted:

1. In the YouTube app, go to your channel and Your videos.
2. Tap More (the three dots) on the Short, then Edit.
3. Pick a new frame, add text or a filter if you like, and tap Done.

Once you finish an edit to the thumbnail, you can't go back to an earlier one, so check it before you tap Done. And you're limited to what's in the Short: for a cover with big, styled words, make the image yourself and upload it in Studio on a computer.

What YouTube recommends for a Short's custom thumbnail:

• Shape: 9:16, the shape of the Short.
• Size: 2160 × 3840 pixels, and at least 640 pixels tall. Use the largest image you can.
• File: a JPG or PNG, under 50 MB when you upload it on a computer.

2160 × 3840 is exactly twice 1080 × 1920, so a cover made at either size has the same layout. Make it big for YouTube and the smaller copy for TikTok.

Where people see it. YouTube lists where viewers find Shorts: the Shorts feed, the Home tab, Subscriptions, search, and sound and hashtag pages. In the Shorts feed a Short starts playing as soon as it's on screen, so the thumbnail isn't what people see there. Everywhere else, Shorts show as tiles next to others, including on your channel's Shorts tab, and the thumbnail is what someone decides on. That matters: YouTube says it ranks Shorts partly on the share of viewers who choose to watch one when it's shown to them.

YouTube doesn't publish how each of those pages crops a Short's thumbnail, so design for the middle of the frame: more on that below.

A Shorts thumbnail is seen small and in a hurry, between other covers. What works:

• One clear subject. A face mid-reaction, or the object the Short is about, large and sharp. TikTok's advice for its own covers is the same: a clear picture of the person or object as the focus.
• Three to five big words. Say what the Short is or why it's worth a tap (“I quit after one week”, “3 mistakes I made”), not the whole title. Big enough to read on a grid tile.
• Keep it in the middle. Covers are shown at different sizes and shapes, and the edges are what gets cut. Keep the face and the words in the center of the 9:16 frame, clear of the top and bottom.
• Don't cover the face with words. Put the text above or below the subject.
• The same look every time. One font, one color for the key word, the subject in the same place: your channel's Shorts tab reads as a series, and people tap through from one to the next.
• Promise what the Short delivers. YouTube looks at whether viewers stay after they choose a Short, not only whether they tap. A cover that oversells gets the tap and then the swipe.

You can't A/B test a Short's thumbnail: YouTube's test and compare feature doesn't support Shorts. To learn what works, keep one style for a run of Shorts, then try another, and compare how they do. More on what gets Shorts watched in how to get more views on YouTube Shorts.

If you post the same clip to all three apps, you can use the same cover, with one difference in shape. TikTok calls its version a video cover: the thumbnail that previews your video on your profile and in search results. Instagram calls it a reel's cover photo.

• TikTok suggests a 9:16 cover at 1080 × 1920 for the best results, and asks you to keep the subject centered and elements away from the edges, where the For You feed's buttons and text sit. It also suggests the same text template on every cover, so your profile looks put together.
• Instagram suggests a cover a little wider than 9:16. Fitted to that shape, a 1080 × 1920 cover would lose about 12% of its height, roughly the top and bottom 120 pixels: one more reason to keep the words in the middle. Pick the cover before you share, since Instagram's help says you can't change it after.

The free Shorts thumbnail maker makes a 9:16 cover from a frame of your video, with big, bold words in the lettering of Clyper's captions. It runs in your browser, so the video isn't uploaded anywhere:

1. Choose your video, or an image, and slide to the frame you want: a clear face, mid-reaction.
2. Write the title. Put *stars* around a word to color it, and press Enter for a new line.
3. Pick a look (Outline, Yellow or Box), then the size and height of the words. Turn on the guides to see what the apps' buttons cover.
4. Fill the frame: crop a wide video to 9:16 and drag to choose what stays, or fit the whole picture on a blurred copy of itself.
5. Download a 2160 × 3840 JPG for YouTube, or 1080 × 1920 for TikTok and Reels. Free, with no watermark.

Under the preview, it shows the cover small, the way it looks on a profile beside two others. To compare with Shorts that do well in your niche, the free YouTube thumbnail downloader gets any video's thumbnail from its link, Shorts links included: study them, but make your own.

A cover earns the tap; the Short has to hold the viewer after it. If you're cutting Shorts from your long videos, the work is in finding the moments, cutting them on whole sentences, reframing to 9:16 and captioning every word. That's what Clyper does: paste the video's YouTube link and it makes the Shorts, then you make the covers.
