What is the maximum size for an image in Marketo?

The maximum size for an image in Marketo is 100 MB. Marketo allows users to upload images for various purposes, including email campaigns and landing pages, and ensuring that the image size remains within this limit allows for optimal performance and faster loading times. By adhering to this limit, users can be assured that their assets remain manageable within the platform's infrastructure, reducing the likelihood of issues related to image rendering and user experience.

In practice, keeping images within this size limit also prevents unnecessary strains on bandwidth and helps maintain the overall efficiency of the marketing operations performed within Marketo. This is particularly important in large campaigns where numerous images might be utilized, as larger files could lead to longer loading times for recipients and potentially hinder engagement.
