This article outlines the recommended specifications for images, GIFs, and videos. For feed card character count specifications, check out this article. If you are looking for specifications about images that impact the look and feel of your community, i.e. branding, please check out the Branding Assets Glossary.
For cover images, as these are subject to some cropping, aim for a 16:9 landscape ratio (1920x1080 pixels), as this will tend to look the best across channels (such as email, web, or mobile). Please see the article on optimizing image appearance for more details.
In image blocks, we support image files in JPG or PNG format with a file size of up to 5 MB. Please ensure your file is smaller than 5 MB for a successful upload. Depending on the ratio of the image block, you may aim for a 16:9 landscape ratio (1920x1080 pixels) or square (400x400 pixels). And banner images should be at least 800 pixels wide (variable height). Note that nothing, including image blocks, will be cropped in the “full view” of the campaign. So any numbers we cite, like 400 pixels for half-width, 800 pixels for full-width, only apply to resolution.
For topic thumbnails, the recommended ratio is 1:1.1. (For example: 200x220 pixels, 400x440 pixels, 800x880 pixels, or 1600x1720 pixels).
Images are compressed when they are uploaded, which may result in a small reduction in image quality for JPG format images. PNG images benefit from lossless compression, meaning there will be no loss of image quality when a PNG image is uploaded.
Generally, you can upload or insert GIF files wherever you can upload or insert image files. We have found that GIF files embedded in the body of article campaigns tend to work across the platforms (Studio, web experience, mobile app). However, we have found that GIF files that are the header/cover image of a campaign fail to load for users in their feed. Therefore, due to a combination of file sizes and network issues, we cannot assure that a GIF will load for all users.
When uploading a video, the file should be smaller than 500 MB and in MOV, MP4, or AVI format. If you can optimize or compress the video to a smaller size, that will make the upload and processing go faster. Please keep your mobile app users in mind - larger files will be hard to load over some data connections.
