Create ads in Campaigns

Generate ad creative from your campaign pages, then launch it from the Activate tab.

Your campaign already has the message, visuals, and audiences. Turn them into ads without starting from scratch. Upload a reference image, generate ads in the sizes you need, personalize them for each audience, then send them to Google Ads without leaving Webflow.

Create your first ad

Your reference image is the initial ad that Webflow bases the design on. You can also add up to four supporting assets — extra images you want displayed in the ad, like a product screenshot or a headshot of a speaker.

Use a JPEG, PNG, or WebP reference image up to 30 MB. Supporting assets must be JPEG, PNG, or WebP, up to 10 MB each.

To create your first ad:

1. Open your campaign and go to Build > Ads
2. Click Upload past ad creative
3. Choose an image to use as your reference image
4. Click Upload in a Supporting assets slot to add extra images (optional)
5. Click Generate first ad

Webflow creates Creative set 1 with a Base version of your ad, sized to the supported ad size closest to your reference image.

Edit your base image with prompts

Describe the changes you want in plain language, and Webflow updates your ad. You can change the text, colors and styling, or images and logos. To edit your base image:

1. Click Edit image on your base image
2. Describe your change, such as “Change the call to action to Register now”

Keep prompting until the ad looks right. You can edit any ad size the same way.

Generate ad sizes

The Base image row shows one card for each supported size. Each card lists the size name and its aspect ratio. Scroll sideways to see them all. To generate a size:

1. Go to Build > Ads
2. Find the size you need in the Base image row
3. Click Generate

To save a size, click the download icon below its card.

Supported ad sizes

Here's how each size maps to common platforms and ad formats.

Create ad variations

Variations let you personalize your ads for the audiences in your brief. After you generate your first ad, a prompt offers to create a variation for each audience it finds. To generate ad variations:

1. Go to Build > Ads
2. Click Generate variations in the Generate ad variations prompt

Each variation shows up in the Variations list with a Ready label. Click a variation to see its ad sizes. Each variation has its own sizes, so generate the ones you need for each. If you click Dismiss, you can add and edit variations later.

To work with a single variation, click the more options icon next to it, then choose:

• Update supporting images — change the extra images shown in that variation's ads
• Download — save that variation's ads

The Base version only has the Download option.

Create another creative set

Want to try a different look? Start a new creative set below your current one. To create another creative set:

1. Go to Build > Ads
2. Click Upload past ad creative below your existing creative set
3. Choose an image to use as your reference image
4. Click Upload in a Supporting assets slot to add extra images (optional)
5. Click Generate creative set

Manage your creative set

Click the more options icon next to the creative set name to:

• Rename — give your creative set a new name
• Edit source images — update the images your ads are based on. Generating from new source images resets the whole creative set, including its sizes, variations, and edits.
• Download all — save all of your generated ads at once

Push your ads into channel

The Activate tab connects everything you generated to an ad partner, all within Webflow. To start:

1. Click Activate in the top bar
2. Click Start next to Google Ads under Select ad partner

To finish setting up your ads, follow the steps in Launch Google Ads from Campaigns.
