When exporting a Flexitive design as HTML5 for an ad server, you can either export the design as a Live design using 3rd party tags or an Offline design as an HTML5 .ZIP file. Learn more about Offline vs Live Files.


The file type you will need to export will vary based on the ad server you are using. To see which file types are supported by each ad server, please see our article on Ad Servers and DSPs Supported by Flexitive.

Publishing Designs Before Exporting

Before exporting your design from Flexitive, you will need to Publish your design. Publishing your design will automatically save your design and update any live files of the design exported from Flexitive. Learn more about Publishing your Design.

Choose Offline or Live Files

To export your Flexitive Design as HTML5 for an ad server, go to the Export panel and select the ‘Ad Server / DSP’ tab. Then, choose between exporting Offline or Live Files. 

Not all ad servers support Offline Files, and not all ad servers support Live Files. To see a list of ad servers & DSPs, and whether they support live or offline files, check out our related support article here: Ad Servers and DSPs Supported by Flexitive

Offline Files

Exporting an offline design as a ZIP will provide you with a ZIP file containing each size you have chosen to export. The exported designs include all the images and code necessary for hosting the design, and the images will be cropped and compressed to their lowest possible file size without sacrificing image quality.

Live Files

Live designs can be exported as 3rd party tags. Exporting Tags will provide an XLSX file containing scripts that you can use to host your designs. This script calls the Flexitive CDN to display the design.

Designs exported as a Live File can be updated to the most recent version of your design by publishing the design in Flexitive. Any updates you made to your design will be automatically pushed to the Live files without having to re-export or re-traffic those designs. 

Designs exported as live files for Ad Servers are hosted on the Flexitive servers, so serving fees will apply.

Select an Ad Server

The Ad Server / DSP dropdown can be found under the 'Ad Server/DSP' tab. Use the 'Ad Server/DSP' dropdown to select your ad server. If you are not exporting for a specific ad server, select Generic Ad Server (Flexitive).

Only one ad server may be chosen per export. If you require exports for multiple ad servers, you will need to separately export for each ad server you need. If you need to export for an ad server that isn't available contact a member of the Flexitive Support team at

Set Export Properties

Once you've chosen an ad server to export form, you will be able to set properties for your design.
