The Last YouTube Companion Banner Resizer You'll Ever Need (300x60)

Free, Instant, and Perfectly Sized. Stop the struggle and get back to your campaign.

We’ve all been there.

Your video ad is polished and ready to go. You’re in the final stretch of launching your campaign in Google Ads, and then you hit the wall: the companion banner.

It demands a tiny, awkward 300x60 pixel image. Everything you try to upload looks like a disaster—stretched, blurry, with your logo cut in half. You’ve spent way too much time fighting with it, and your frustration is building.

This shouldn't be the hard part.

That's why we made this tool. It’s a simple, no-nonsense companion banner resizer. Just give it your image, and it gives you back a perfect, crisp 300x60 banner that meets all of YouTube’s 2025 ad requirements. Problem solved.

That Tiny Banner? It’s a Click Magnet.

So why wrestle with this little banner? Because it’s one of the most underrated parts of a successful YouTube campaign.

Think of it as your ad's anchor. While your video plays, this clickable banner sits right beside it on desktop, constantly visible. When the video ends or the viewer skips, it remains, offering a persistent link to your website or offer. A great companion banner can significantly lift your click-through rate (CTR) and conversions.

Here are the official specs you need to nail:

• The Oddball Size: 300 pixels wide by 60 pixels tall.
• The Right Format: A standard JPG, PNG, or GIF.
• The Featherlight Weight: Must be under 150 KB.

Our resizer automatically handles all three.

Design Tips for a 300x60 Banner That Actually Converts

Getting the size right is step one. Getting the clicks is step two. Here’s how to design a banner that works as hard as your video does.

1. One Single Focus. You have zero room for clutter. Pick ONE thing you want the viewer to do. Is it "Get 50% Off"? "Download the Guide"? Make that the hero. Your logo should be secondary.
2. A "Can't-Miss" Call-to-Action (CTA). Use a clean, bold button or text that creates urgency. Words like "Now," "Today," or "Free" are your best friends. Viewers need to be explicitly told what to do.
3. Match the "Scent". Your banner's design, offer, and message should perfectly match the landing page it clicks through to. If the banner screams "50% Off Blue Widgets," the landing page better have blue widgets front and center at 50% off.
4. Punchy Contrast. Your banner is fighting for attention. Use bold, high-contrast colors that pop against YouTube's interface. Think a bright button on a simple background.

Your Questions, Answered (The Nitty-Gritty FAQ)

Q: Seriously, why does my image always look so distorted?

A: It's the "square peg in a rectangular hole" problem. Your source image is likely a different shape (aspect ratio) than the banner. When you force it, the software stretches it. Our tool is smarter—it helps you crop the image to fit the 5:1 ratio perfectly without distortion.

Q: My banner looks sharp, but now it's not showing up with my ad. What's wrong?

A: This is a classic issue! Here are the two most common culprits:

• You're on your phone. The 300x60 companion banner is a desktop-only format. It will never show up on mobile, tablet, or TV apps. Check your ad on a laptop or desktop computer.
• Google Ads Settings. Companion banners are only available for certain campaign types (like In-stream ads). Also, if you let Google auto-generate a banner from your channel, it may override your upload. Always select the option to upload your own custom image.

Q: Can I just skip it and let YouTube make one for me?

A: You can, but you shouldn't. The auto-generated banners are notoriously bad. They grab a random slice of your main channel banner, which almost never looks good in the 300x60 format. It's the fastest way to make a great ad campaign look unprofessional.
