How to Add a YouTube Video Watermark
A YouTube video watermark is a small branding image that appears over your videos. It can help reinforce your channel identity and give viewers a quick subscription prompt on supported devices. It is usually a simple logo, icon, or subscribe-style mark.
The video watermark is part of YouTube channel branding. You add it once in YouTube Studio, choose when it appears, and YouTube applies it to eligible videos. You can choose to show it for the entire video, from a custom start time, or only during the final 15 seconds.
A watermark is not a magic growth tool. It will not fix weak videos, poor packaging, or unclear calls to action. But it can add a consistent visual reminder and support brand recognition, especially on long-form videos where viewers spend more time with your content.
This guide explains how YouTube video watermarks work, how to add one, what image requirements matter, when to show it, why watermarks do not appear on some videos, how they differ from end screens, and how creators, businesses, and agencies should design them properly.
The Short Answer
To add a YouTube video watermark, sign in to YouTube Studio, go to Customisation, open Profile, find the video watermark section, choose the display time, upload a square image, adjust it, then publish.
You can choose one of three display timings: end of video, custom start time, or entire video. End of video shows the watermark for the last 15 seconds. Custom start time begins at the time you choose. Entire video shows it throughout the video.
Your watermark image must be a square image at least 150 x 150 pixels and less than 1 MB.
What a YouTube Video Watermark Does
A video watermark adds a small branding mark to eligible videos. On supported surfaces, viewers can use it as a channel subscription prompt.
It can help with:
- Brand recognition
- Channel consistency
- Subtle subscription prompts
- Professional presentation
- Visual ownership of long-form videos
It should be subtle enough not to distract from the video, but clear enough to recognise at small size.
How to Add a Video Watermark
The basic process is:
- Sign in to YouTube Studio.
- From the left menu, select Customisation.
- Open Profile.
- Find the video watermark section.
- Select the display time.
- Click Change and upload an image.
- Adjust the image size if needed.
- Click Done.
- Click Publish.
After publishing, check a normal video watch page on desktop and mobile to see whether the watermark appears as expected.
Watermark Image Requirements
YouTube video watermark images must meet basic requirements.
The image should be:
- Square
- At least 150 x 150 pixels
- Less than 1 MB
- Clear at small size
- Consistent with your channel branding
A transparent PNG often works well because it can sit over video footage without an ugly box around it. Avoid detailed artwork that becomes unreadable when scaled down.
What Should the Watermark Look Like?
The best watermark is simple. Viewers see it small, so tiny words and complex designs usually fail.
Good watermark options include:
- A simple channel icon
- A clean logo mark
- A high-contrast symbol
- A subscribe-style button
- A simplified brand monogram
Avoid:
- Long words
- Tiny text
- Low contrast colours
- Complex illustrations
- Busy backgrounds
- Marks that cover important video details
Design for the real display size, not for how it looks in your design software.
Display Option 1: End of Video
The end of video option shows the watermark for the last 15 seconds. This is the least intrusive option because the viewer has already watched most of the video.
Use end of video when:
- You want a subtle subscribe prompt
- You do not want the watermark visible throughout
- Your videos have clean endings
- You already use strong visual branding earlier
The downside is that viewers who leave early may never see it.
Display Option 2: Custom Start Time
Custom start time lets you choose when the watermark begins showing. This is useful when you want the video to start clean, then show the watermark once the viewer is settled.
For example, you might start it after the opening hook or after the intro section.
Use custom start time when:
- Your opening visuals should stay clear
- You want a balance between visibility and subtlety
- You want the watermark to appear after the viewer has committed
- You have a predictable video structure
This is often the best compromise for polished channels.
Display Option 3: Entire Video
Entire video shows the watermark throughout the video. This gives maximum exposure but can be distracting if the mark is too bold or if your videos include important visual detail near the watermark area.
Use entire video when:
- Your watermark is very subtle
- Your videos are long
- Your brand identity matters strongly
- The watermark does not cover important information
Do not choose entire video just because it seems like more is better. If it distracts viewers, it is doing the wrong job.
Why Your Watermark May Not Show
Video watermarks do not appear everywhere.
Common reasons include:
- The video is set as Made for Kids
- The viewer is on a surface where watermarks are not supported
- The video is playing in a custom chromeless player
- The update has not appeared yet
- The image does not meet requirements
- You are checking during an end screen where other interactive elements can be suppressed
If a video is set as Made for Kids, viewers will not see the watermark.
Watermarks and Made for Kids Videos
YouTube video watermarks are not available on videos set as Made for Kids. If you previously added a watermark and later set a video as Made for Kids, viewers will not see the watermark on that video.
This is important for channels that publish a mix of general audience and child-directed content. Do not rely on watermarks for Made for Kids videos.
Watermarks vs End Screens
Watermarks and end screens are different tools.
A watermark is a small branding image that appears during the video based on your display timing. An end screen appears near the end of a video and can promote videos, playlists, and subscriptions.
Use the watermark for subtle channel branding. Use the end screen for a clearer next step.
Do not expect one tool to do the whole job. A watermark can support recognition, but a strong end screen can guide the next watch more directly.
Can Watermarks Improve Subscribers?
A watermark can help remind viewers to subscribe, but it should not be treated as a growth strategy by itself. Viewers subscribe when the channel gives them a reason to want more.
A watermark works best when combined with:
- Clear channel positioning
- Strong videos
- Useful playlists
- Good end screens
- Natural spoken calls to action
- Consistent upload topics
Think of it as a small friction reducer, not a persuasion engine.
Watermark Metrics
YouTube lets creators see watermark-related subscription source metrics in YouTube Analytics. This can help you understand whether viewers are using the watermark to subscribe.
Check metrics occasionally, but do not overreact to small numbers. The watermark is one of many possible subscribe paths.
Business Channel Watermarks
Businesses should use a watermark that matches the brand but does not distract from the video.
Business checklist:
- Use an approved logo or icon
- Keep it simple
- Use a transparent background where appropriate
- Check contrast on light and dark footage
- Test on desktop and mobile
- Decide whether entire video or custom start time is best
- Check videos with product demos or screen recordings
If your videos include screen details, make sure the watermark does not cover buttons, dashboards, captions, or product features.
Agency Workflow
Agencies should include the watermark in the channel branding checklist.
Workflow:
- Get the approved logo asset
- Create a square watermark version
- Keep file size under 1 MB
- Upload in YouTube Studio
- Select display timing
- Publish
- Check a live video
- Document the setting for the client
Do not upload a random client logo without checking how it looks at small size.
Common Mistakes to Avoid
Avoid these mistakes:
- Using tiny text
- Using a detailed logo that becomes unreadable
- Choosing entire video when it distracts
- Forgetting Made for Kids videos will not show the watermark
- Assuming watermarks show on every player
- Not checking how the watermark looks on real videos
- Using a low contrast image
- Expecting the watermark alone to drive subscriptions

Final Thoughts
A YouTube video watermark is a small branding tool that can support recognition and subscriptions. It is easy to add, but it should be designed carefully because it appears over the video itself.
Use a simple square image, keep it under 1 MB, choose a sensible display time, and check it on real videos before assuming it works. For most channels, a clean icon with a custom start time is safer than a loud watermark across the entire video.
For creators, the watermark can reinforce identity. For businesses, it can make videos feel consistent. For agencies, it should be part of the documented branding setup. Keep it useful, subtle, and aligned with the viewer experience.
