Change a thumbnail on YouTube

You can change the thumbnail of a regular YouTube video in YouTube Studio. Open Content, choose the video, and select an automatically generated image or upload your own image. Then click Save. In the YouTube Studio app, open the video, tap Edit, and then tap Edit thumbnail.

You can only upload a custom thumbnail if your channel has access to this feature. Different rules apply to YouTube Shorts. With a Short, you cannot add a new custom thumbnail in the same way after upload.

Below you will find the steps for a computer, iPhone, and Android. You will also read why a thumbnail sometimes does not change, which technical requirements apply, and how to make a clear image.

What is a YouTube thumbnail?

A thumbnail is the preview image people see with your video. It appears in search results, on your channel, and next to recommended videos. A clear thumbnail helps a viewer quickly understand what your video is about.

YouTube can automatically suggest a few frames from your video. For regular videos, you can also upload your own image. Your account must be verified and must have access to the right feature.

Changing a thumbnail does not change the content of your video. The video title, description, comments, likes, publish date, and existing views stay the same.

Can you still change a thumbnail after publishing?

Yes. For a regular YouTube video, you can choose a different suggested image or upload your own file even after publishing. It may take some time before the change appears everywhere.

So you do not need to delete the video and upload it again. If you do that, you can lose existing data, comments, and the current video link.

Does this also apply to a YouTube Short?

Not completely. YouTube says you cannot upload a custom thumbnail for a Short in the same way as for a regular video. During upload, you can select a frame from the Short. That frame can appear in search results, on hashtag pages, on audio pages, and on your channel.

After upload, you cannot change the chosen frame again, according to YouTube. So check it carefully before you publish the Short. Also read what you can check when YouTube Shorts are not getting views.

Where do you find the thumbnail setting on YouTube?

On a computer, you will find the setting in YouTube Studio. Use this route:

1. Go to YouTube Studio and log in.
2. Click Content on the left.
3. Click the video you want to edit.
4. Find the Thumbnail section in the video details.
5. Choose a suggested image or click Upload thumbnail.
6. Click Save in the top right.

On a phone, you can change the thumbnail in the YouTube Studio app. On Android, YouTube also offers a route through the regular YouTube app.

Image suggestion 1: show the Content screen in YouTube Studio and highlight the video that needs to be edited.

Image suggestion 2: show the Thumbnail section in the video details. Highlight the upload and save buttons.

How do you change a YouTube thumbnail on a computer?

First open the new image and check whether the text, face, and main subject are sharp. Save the file as JPG, PNG, or GIF. For regular videos, YouTube recommends a 16:9 ratio.

Then follow these steps:

1. Open studio.youtube.com.
2. Check in the top right that you are using the correct channel.
3. Choose Content on the left.
4. Find the right video. Use the search bar if you have many videos.
5. Click the title or thumbnail of the video.
6. Go to the Thumbnail box.
7. Choose an automatically generated image or click Upload file.
8. Select the image on your computer.
9. Check whether the crop looks good.
10. Click Save in the top right.

Then open the regular video page in a new window. Do you still see the old image? Refresh the page after a few minutes. The change is not always visible everywhere right away.

What size does YouTube recommend?

YouTube recommends an image that is as large as possible. The official help page mentions 3840 by 2160 pixels, with a minimum width of 640 pixels. A 16:9 ratio works best for most YouTube players and preview displays.

On a mobile device, a video thumbnail may be no larger than 2 MB according to YouTube. On a computer, the stated limit for thumbnails of videos and podcasts is 50 MB. A smaller, well-compressed JPG file is usually more than enough.

Preferably do not use a small image that has to be enlarged a lot. Text, faces, and other details can become blurry.

How do you avoid a bad crop?

Do not place important information right at the edge. Also keep in mind the time stamp YouTube may show in the bottom right. Do not put a small logo or important word there.

Always check the thumbnail at phone size. A design can look clear on a large screen but still become unreadable on mobile.

How do you change a thumbnail on iPhone or Android?

The clearest route on an iPhone or Android phone is through the YouTube Studio app:

1. Open the YouTube Studio app.
2. Tap Content at the bottom.
3. Select the video you want to edit.
4. Tap the pencil for Edit.
5. Then tap Edit thumbnail.
6. Choose an automatic image or Custom thumbnail.
7. Select an image on your phone.
8. Confirm your choice.
9. Tap Save.

Give the app access to your photos if you want to choose your own image. Only grant the access that is truly needed. You never need to enter your YouTube password in an external thumbnail app.

On Android, YouTube also describes a route through the regular app. Tap your profile picture, open Your videos, tap the menu next to the video, and choose Edit and Edit thumbnail. The exact menu labels may vary slightly depending on your language settings or app version.

Why can’t you upload your own thumbnail?

The button for a custom thumbnail may be missing or show an error message. First check whether you are working on a regular video or a Short. Then check your account, channel permissions, and image file.

Your account is not verified yet

YouTube gives verified accounts access to custom video thumbnails. In YouTube Studio, open the eligibility page for features and check which features are active for your channel. Only follow YouTube’s official verification route.

You do not have the right channel role

Do you work on a channel with multiple people? Then your channel role can affect what you are allowed to change. Check whether you are signed in with the correct account and have enough permissions for the video in question.

You have reached the daily limit

YouTube limits how many custom thumbnails a channel can upload per day. Are you seeing the message that the daily limit has been reached? Then wait 24 hours according to YouTube and try again.

The limit can vary by country, region, and channel history. It is not useful to keep trying the same failed upload over and over.

Your file has the wrong format or is too large

Use JPG, GIF, or PNG. Reduce the image if the file is above the allowed limit. Then save a new version and try uploading it again.

Also check the file name. A simple name without strange characters can prevent local problems. The file name does not affect your position on YouTube.

Your thumbnail does not meet the rules

Thumbnails must follow the Community Guidelines. YouTube mentions nudity, sexually explicit content, hate, violence, and harmful or dangerous content as possible reasons for rejection.

If violations happen repeatedly, YouTube may temporarily remove the rights for custom thumbnails. In serious cases, the channel can be restricted further. So do not use a shocking or misleading image that promises something different from what the video shows.

You are working on a YouTube Short

For Shorts, you cannot upload a custom file after publishing in the same way as with regular videos. That is not a technical error. So choose the correct frame during upload and check it before you publish the Short.

Why do you still see the old thumbnail after saving?

YouTube warns that it may take some time before a changed thumbnail is visible everywhere. Wait a few minutes and then reload the page.

Then check:

• whether you really clicked Save;
• whether you opened the correct channel;
• whether you edited the correct video;
• whether the new thumbnail is visible in YouTube Studio;
• whether your browser is still showing an old image;
• whether YouTube may have rejected the thumbnail.

If needed, open the video in a private window. That way you can see what a visitor sees without old local browser data. Do not delete the video just because the image does not change immediately.

Can clearing the cache help?

Clearing the cache can help if only your app or browser keeps showing an old version. It does not make YouTube approve a rejected thumbnail.

Start by refreshing the page. You can also fully close and reopen the app or use a different browser. Do not clear saved passwords or full app data if you do not know what will be removed.

What changes after you edit a thumbnail?

Only the preview image of your video changes. The video link, existing views, comments, likes, and publish date stay the same.

A new thumbnail does not guarantee extra views. But the image can make it clearer what a viewer can expect from the video. So do not look only at clicks. Also check whether people keep watching and whether the video delivers on the promise of the image.

Does a thumbnail affect your ranking?

YouTube does not publish a simple rule that says a new thumbnail automatically results in a higher ranking. The image is mainly a choice aid for viewers. An honest and clear thumbnail can help attract the right people.

Do not use misleading text or exaggerated visuals. Many clicks without satisfied viewers is not a good end goal for your channel.

Should you replace old thumbnails often?

Only replace a thumbnail when there is a clear reason. Think of unreadable text, the wrong subject, outdated information, or an image that does not fit the video title well.

Do not change the thumbnail every few hours. Give a design enough time and note the date of the change. That way you can compare the results more accurately.

How do you compare an old and a new thumbnail fairly?

Before changing it, write down the date, the number of impressions, and the click-through rate. Also note whether you changed the title, description, or promotion at the same time. Preferably do not change everything at once. Otherwise you will not know later which change made the difference.

Do not compare a quiet Tuesday directly with a busy weekend or a day when your video was shared externally. Look at a long enough period and compare similar traffic sources. A new thumbnail can perform differently in search results than on your channel homepage.

Also look at watch time and satisfaction. A higher number of clicks is only useful when the image creates the right expectation. If many viewers leave the video immediately, the thumbnail, title, and content may not match well.

Does paid support change the thumbnail?

No. Services for extra reach do not automatically adjust your thumbnail. If you want to support your channel’s growth alongside a clear presentation, first see how buying YouTube subscribers works. Always make sure your channel has clear and valuable content of its own.

If you organize live broadcasts, a recognizable thumbnail is also important. Extra options such as buying YouTube livestream views do not replace a good title, content, or image.

How do you make a clear YouTube thumbnail?

Start with the main question of your video. Show one important subject and use only text that is truly needed. A small image full of words is hard to understand, especially on a phone.

Use this practical checklist before you upload the thumbnail:

• use one clear main image;
• make sure there is enough contrast;
• keep text large and short;
• let the title and thumbnail support each other;
• do not promise anything that is not in the video;
• check the image on mobile size;
• keep important information out of the bottom right corner;
• only use images you have permission to use.

How much text should you put on a thumbnail?

Use as few words as possible. A short message is usually faster to read than a full sentence. Also do not repeat the full video title without a reason. Use the thumbnail to make the subject visually clearer instead.

Check the design by making the image small on your screen. Can you still recognize the main subject and the most important words? Then the chance is greater that the thumbnail will also stay clear on mobile.

How do you build a recognizable style?

A strong channel is built from more than separate images. Work on recognizable topics, clear titles, consistent colors, and a style that fits your videos. Viewers can then recognize your content more quickly.

If you want to assess your channel more broadly, read what you should know before buying a YouTube channel. For most creators, building their own channel slowly is the safest route.

Which questions are often asked about changing a thumbnail on YouTube?

Where do I find the feature to change a thumbnail?

Open YouTube Studio, choose Content, and select the video. You will find the setting in the Thumbnail section of the video details.

Does this work on iPhone and Android?

Yes, for regular videos. Use the YouTube Studio app, open Content, select the video, and tap Edit and Edit thumbnail.

Can I undo the change later?

For a regular video, you can later choose another image again. Keep the old file if you want to go back to the exact previous design.

Why do I not see the option?

You may be working on a Short, your account may not be verified, you may not have the right channel role, or the feature may be limited. Check feature eligibility and your permissions in YouTube Studio.

Does changing it affect existing content?

No. Only the preview image changes. The video, video link, publish date, views, likes, and comments remain.

How fast does the new thumbnail appear?

YouTube does not mention a fixed processing time. It may take some time before the change is visible everywhere. Wait a few minutes and then check the video again.

Can I upload my own thumbnail for a Short?

Not in the same way as for a regular video. For a Short, you select a frame from the video during upload. According to YouTube, you cannot change that chosen frame after publishing.

Which step should you take next?

Open YouTube Studio and first check whether it is a regular video or a Short. For a regular video, make a clear image in a 16:9 ratio. Upload the image, check the crop, click Save, and give YouTube a little time to process the change.

Is the button missing? Then check your account verification, channel role, file format, file size, and daily limit. Do not delete the video. In the event of a technical error, you can also check whether the video itself is available and what the message video not available on YouTube means.
