YouTube thumbnail policy: what gets a thumbnail removed (and what happens next)
What YouTube won't allow in a thumbnail, when it removes one without a strike, what a strike does to custom thumbnails, and how to appeal a removal.
6 min read ThumbnailsYouTubeGuidesStudioA bold thumbnail gets clicks. But YouTube has rules for what can go in that image, and breaking them can cost you the thumbnail, your custom thumbnail access for a while, or more.
This guide covers what YouTube bans, the gray zone where you lose the thumbnail but get no strike, what a warning and a strike actually do, and how to appeal. If your thumbnail just isn't appearing and you never got a notice, start with [why your YouTube thumbnail isn't showing](/blog/youtube-thumbnail-not-showing) instead.
What YouTube won't allow in a thumbnail
The rules reach past thumbnails. YouTube's [Thumbnails policy](https://support.google.com/youtube/answer/9229980) covers banners, avatars, posts, and any other YouTube feature that has images.
YouTube says not to post a thumbnail or other image if it shows:
YouTube adds that "the above list isn't complete." So treat it as the starting point, not every case.
That last item is the one most creators brush up against. Opening a curiosity gap is fine, and it's a big part of [the psychology behind thumbnails that get clicked](/blog/youtube-thumbnail-psychology). Showing something that never happens in the video is where it crosses the line.
YouTube also says it may make exceptions for content with educational, documentary, scientific, or artistic context. That's a judgment YouTube makes case by case, so don't count on it for a borderline image.
The gray zone: age restriction or removal with no strike
Some thumbnails aren't right for every audience but don't break the Community Guidelines. For those, YouTube says it may age-restrict the video or remove the thumbnail, but it won't issue a strike on your channel.
If it removes the thumbnail, YouTube lets you know and you can upload another one. In YouTube Studio, select **Content**, then click the video's title or thumbnail to open **Details**. Below **Thumbnail**, click **Upload file**, then click **SAVE**. [How to change a YouTube thumbnail](/blog/how-to-change-youtube-thumbnail) has the full walkthrough.
Here's what YouTube looks at when it makes that call:
Two things stand out. The focal point matters, not just whether something appears in the frame. And YouTube reads the whole upload, so a shock title can pull a tame image into review.
What happens when a thumbnail breaks the rules
If a thumbnail contains pornography, YouTube says it may terminate the channel. For other violations, it removes the thumbnail and may issue a strike.
The first time is usually a warning
If it's the first time you've posted something that breaks the Community Guidelines, YouTube says you'll likely get a warning with no penalty to your channel.
The optional policy training
YouTube describes policy trainings as short in-product lessons based on the policy you broke. You'll find the training in the YouTube app and in Studio, on the dashboard and the Content tab. The warning email and banner also link to it.
Finish the training and your warning expires after 90 days. Per YouTube's [strike basics](https://support.google.com/youtube/answer/2802032), that 90 days starts when you complete the training, not when the warning was issued.
If you break the same policy within that 90-day window, the warning may not expire, and your channel may get a strike.
A few limits apply. Not every warning is eligible for training. If you break a different policy after you finish it, you get another warning. YouTube may also stop repeat offenders from taking trainings.
What a strike does to your custom thumbnails
A first strike means that for 1 week you can't create custom thumbnails or posts. You also can't upload videos, schedule anything to go public, or create a Premiere during that week.
After the week, YouTube restores your privileges automatically, but the strike stays on your channel for 90 days. A second strike in that same 90 days means you can't post content for 2 weeks. Three strikes in 90 days may get the channel permanently removed.
YouTube's [custom thumbnails page](https://support.google.com/youtube/answer/72431) adds two thumbnail-specific effects. Repeat offenses may lead to the removal of your custom thumbnail privileges for 30 days. Strikes also affect how many custom thumbnails you can upload each day.
If the **Upload file** button is missing and you have no strike, the cause is usually verification. [How to enable custom YouTube thumbnails](/blog/how-to-enable-custom-youtube-thumbnails) covers that fix.
How to appeal a removed thumbnail
When a thumbnail is removed for a Community Guidelines violation, YouTube sends you an email. If you think it was removed by mistake, use the form in that email to appeal.
Timing depends on what you're appealing. YouTube's [appeals page](https://support.google.com/youtube/answer/185111) gives you up to 1 year after a removal, and that window covers thumbnails. For warnings and strikes, you can appeal for 6 months after the warning or strike was issued.
To appeal a strike, open YouTube Studio and go to your **Dashboard**. Select the **Channel violations** card, then select **APPEAL**.
YouTube emails you the result. If it finds the thumbnail followed the guidelines, it reinstates it and removes the strike. If it decides the thumbnail is fine but not for all audiences, the custom thumbnail is removed anyway. A rejected appeal carries no extra penalty.
If your appeal is approved and you haven't replaced the thumbnail yet, YouTube may restore it. So if you plan to appeal, it can make sense to wait before uploading a new one. You can appeal each strike only once, so make your reason clear the first time.
A quick check before you upload
Run through this before you hit **SAVE**:
Push it hard, stay inside the lines
None of this means your thumbnail has to be quiet. Strong contrast, a big expression, and a real curiosity gap all fit inside the rules. What YouTube cares about is what the image shows and whether the video delivers on it.
