Currently, there is no way to customize or resize images within Leadpage's Standard Builder. To resize or customize an image, you will need to use a third-party service to do so. Here are some services that allow you to customize and resize your image:
PLEASE NOTE: We cannot support the use of these services, but if you'd like to give them a try we welcome you to do so!
Once you've customized your image, you can re-upload your image to your Leadpages account and use them with your Leadpages and Leadboxes. For more information on how to add and remove images from Leadpages take a look here:
