Lead with the rank and one short claim. A ranked Brawl Stars thumbnail reads best when the rank is the biggest thing in the frame.

Put the number first. A trophy count tells viewers the stakes before they read anything else.

One brawler, one hook. Good for a Mortis, Edgar, Leon, Bibi, Surge or Shelly thumbnail once you add your own screenshot or render.

Keep the rows simple. Viewers only need to see that a ranking exists, not read every entry at phone size.

A big reward and a big reaction. Use the count or the rarest drop as your second line.

Make the new thing the hero. Works for new brawlers, balance changes and update reactions.

Show two sides and what is at risk. A split-color frame makes the matchup obvious.

See credit packsDescribe the video, choose a video type and the AI Brawl Stars thumbnail generator builds a full 16:9 scene in the loud, saturated look the game's channels use. Add a headline and it is rendered as you typed it, and you can keep editing the result in the app.
It has no built-in brawler library. Without a reference image it invents an original character in the same style. For a specific brawler, upload a screenshot or render you have permission to use. Check the spelling of any headline before you upload the thumbnail.
Good Brawl Stars YouTube thumbnail design comes down to a few choices that survive a small phone screen.
Give one brawler or object a large part of the frame. Small characters disappear in the feed.
The title does the explaining. A cool Brawl Stars thumbnail adds a hook instead of repeating it.
Use saturated colors, a thick dark outline on text and a glow behind the subject so it lifts off the background.
Trophies, ranks, days and box counts give viewers a reason to click.
A clickbait Brawl Stars thumbnail only works if the video pays it off. Exaggerate the moment, not the facts.
A Brawl Stars thumbnail for YouTube follows the same rules as any custom thumbnail. The free editor already exports at the recommended size.
YouTube covers the bottom-right corner with the video length, so keep text and faces out of it. The editor's corner guide shows that area and never appears in your download. 2K and 4K AI images can be larger than 2 MB, so resize them or save them as JPG before uploading.
This tool does not include Supercell art. Here is where the pieces of a Brawl Stars thumbnail usually come from.
ThumbBlox is an independent tool, and this page ships no Supercell logos, characters or game art. You choose what goes into your Brawl Stars thumbnail, so only use images you have permission to use and follow Supercell's Fan Content Policy.
