Convert HTML documents to video or image ads

If you want to use an HTML document created in Google Web Designer as the basis for a video or image ad, you can convert the document instead of building the video or image ad from scratch.

Conversion types

Web Designer can handle the following document type conversions:

Convert from	Convert to
Most HTML documents, including: Banner ad Expandable ad Interstitial ad HTML document with pages	Video ad (except on Linux) Image ad

HTML documents without pages, AMPHTML ads, video ads, image ads, and animated GIFs cannot be converted to other types.

Convert a document to a video ad

1. In Design view, select File > Convert document type > Video... from the top menu.
2. In the dialog that opens, configure your video settings and file properties:
   • Page - If your document has multiple pages, select which one should be converted.
   • Size - If your document is responsive, you'll see all serving sizes listed here in a drop-down. Select which size to use for the conversion.
   • Scaling - Select a method for scaling content when the original document and the new video file have different dimensions:
     • Resize to fit - Resize to fit in the new dimensions while maintaining aspect ratio.
     • Crop to fill - Resize to fill the new dimensions while maintaining aspect ratio, cropping the element if necessary.
     • None - No resizing.
     • Stretch to fill - Resize to fill the new dimensions, stretching the element if necessary.
   • Save As - The new document's filename.
   • Location - Where to save the new document.
   • Dimensions - Select a common video size, or Custom to enter a different size.
3. Review any compatibility notes to check which features in your document may not be fully supported in a video ad.
4. Click Convert.

Your video ad will open as a new editable document. To generate an MP4 video file, publish the document.

Convert a document to an image ad

1. In Design view, select File > Convert document type > Image ad... from the top menu.
2. In the dialog that opens, configure your image ad settings and new file properties:
   • Page - If your document has multiple pages, select which one should be converted.
   • Supported Sizes - If your document is responsive, you'll see all serving sizes listed here. To add or remove sizes, close the dialog and make changes in the Responsive panel.
   • Target Time - If your document contains animation, you can specify a specific point in time during the animation timeline. A snapshot of your document at that point will be used for the conversion.
   • Save As - The new document filename.
   • Location - Where to save the new document.
3. Review any compatibility notes to check which features in your document may not be fully supported in an image ad.
4. Click Convert.

Your image ad will open as a new editable document. To generate a JPG or PNG image file, publish the document.
