How to Make LinkedIn Ads with AI (2026 Guide)

You want a LinkedIn ad, but you are not a designer and you do not have a week to spare.

Good news: you can make one yourself with AI in a few minutes.

This guide shows you how, step by step, from a blank canvas to a finished image you can upload to LinkedIn. No design skills needed.

What makes a good LinkedIn ad?

LinkedIn is full of busy professionals at work, not people relaxing at home. They scroll fast, often between meetings. So a good ad is simple and easy to read.

Three things matter most:

One clear message. Say one thing, not five. “Cut hiring time from 3 weeks to 4 days” beats a list of features.
Big, readable text. Keep the words on the image short: a headline of about 6 to 10 words, plus maybe one number. That is the limit.
A clean, plain look. Skip loud colors and busy backgrounds. On LinkedIn, simple looks trustworthy.

Design for the phone first, because most people open LinkedIn on their phone. If it reads well on a small screen, it reads well everywhere.

What size should a LinkedIn ad be?

You mainly need two shapes:

Square (1:1), about 1080 x 1080 pixels. Good for a standalone post. Takes up more space in the feed.
Wide (landscape), about 1200 x 627 pixels. The common size for a link ad with a headline and a button.

You do not have to memorize the numbers. When you set up the ad, LinkedIn tells you the size it wants. Match that.

How do I make a LinkedIn ad with AI?

Here are the steps in VapuAI. Start on the AI LinkedIn ad generator page to see example ads, then do the work in the Studio.

Open the Studio. Go to the Studio. On the left, make sure the tool is set to Generate.
Write a short prompt. In the box at the bottom (“Describe the image you want to generate”), say what you want in plain words. Example: “Professional LinkedIn ad, deep blue background, clean modern style, empty space at the top for a bold headline, small logo in the corner.”
Pick a model. Click the model button in the left sidebar to open the list. Each model has its own style and a credit cost shown next to it. Pick one to start; you can switch and try another anytime.
Set the size. In the sidebar, choose the Aspect Ratio. Use 1:1 for a square ad or 16:9 for a wide one (then crop to the exact size LinkedIn asks for). Set Resolution to 2K or higher so the image stays sharp.
Click Generate. The button shows the cost, like “Generate (2 cr)”. You can also press Ctrl+Enter, or Cmd+Enter on a Mac. Your image appears in a few seconds.
Make a few. Change the model or edit the prompt and generate again. Making three or four options is normal. You want a choice, not a single guess.
Download it. When you like one, click Download to save it, or Copy to paste it straight into Canva or a slide.

That is it. You now have an ad image ready to upload.

A note on credits: you pay when an image is created. If a generation fails and no image comes back, we refund those credits automatically, so you only pay for images that actually generate. Commercial rights are included on every plan, so you can use what you make in a paid campaign.

A tip on text: decide your headline and number before you generate. Then either write them into the prompt, or generate a clean background with empty space and add the text on top later in Canva or in LinkedIn’s ad builder. Text you add yourself is always sharper than text baked into an image.

How do I run the ad on LinkedIn?

Once you have the image:

Open LinkedIn Campaign Manager and create a campaign.
Pick your goal: brand awareness, website visits, or leads.
Choose who sees it, by job title, industry, company size, or seniority. This targeting is the main reason LinkedIn ads work for business, so take your time here.
Choose Sponsored Content, upload your image, and add your headline and link.
Start with a small budget. Run two or three versions and keep the one that gets the most clicks.

Common mistakes to avoid

Too much text on the image. One headline and maybe one number. Nothing else.
A busy, loud design. Simple wins on LinkedIn.
The wrong size. A square image in a wide slot gets cut off. Match the size LinkedIn asks for.
Only making one. Always make a few and test them.

Keep it simple, make a few versions, and let the clicks tell you which one works.
