When you are crafting your written description on your game's store page, you are likely inserting images or short animations to illustrate the key features that make your game unique. Our tools make this easier to manage localized versions of these images and add helpful accessibility text for each.

Image and Video Formats

You can upload images and videos as PNG, JPG, GIF, WEBP, MP4, and WEBM, however, animations will only display in the About This and Special Announcement sections of the store page.

We recommend generating images and videos that are 1170px wide in order to maximize quality on high DPI displays (780 logical pixels wide column * 150% DPI scaling). If you upload larger images (up to 4096px wide), viewers will see an option to see the image in full screen, which can be helpful for roadmaps or images with a lot of text.

Animated assets can be a maximum of 12 seconds in duration. When you export videos, include color space information and if possible, set the color space to BT.709. This will guarantee that the final video's color matches the color you expect.

Localized Image Management

If you are uploading images that contain text, you can now easily manage localized version of those images all together in an image group.



This gives you one single entry in your list of images and a quick menu option to edit the group.

Editing the group gives you a pop-up to add, delete, or reassign images to specific languages.



The biggest benefit to managing localized assets as a group is that you don't need separate entries for each language in your written text. Instead, you'll simply insert the same localized image group into every language that you've translated your post into, and Steam will show the correct image to the viewer depending on their language settings.

Accessibility Text

For every image that you place in your written description of your store page, you can add alt text, which will be surfaced to players using screen readers. To add alt text, navigate to your store page editor, select the 'Description' tab and click the blue button right above the 'Upload Custom Image' section. Alt text will also export/import along with your other store page text on the 'Localization' tab.

Asset Error

We currently support the following file types for extra assets: PNG, JPG, GIF, WEBP, MP4, and WEBM. All uploaded assets are automatically transcoded by Steam’s systems. If you encounter an error when uploading an asset, it could be due to a server issue or a transcoding error.

First, please verify that your asset is valid and viewable in a browser. If it displays correctly in your browser but still fails to upload or convert after multiple attempts, please create a support ticket and include a link to the original failing asset file stored on a platform like Dropbox. the ticket system converts all assets provided to jpg and may loose the specific problem we want to address. This will help our team investigate the issue and also improve our transcoding pipeline.
