Asset library

The left rail lists folders for your brand. Folders are flat — there's no nesting — and exist to keep large libraries scannable. Click a folder to filter the grid to that folder. The “All assets” entry shows everything.

Upload Assets accepts most common image and video formats and can take several files at once. To add a whole folder of media, use Upload Folder or drag a folder straight into the library — every supported file inside is uploaded, and anything unsupported is skipped automatically. Files larger than the brand limit are rejected on the client; the limit is shown in the upload area. After upload, the asset shows its original dimensions and file size.

Each asset has an optional description — a short, internal note about what the asset is and when to use it. Click any asset to open its details, where you can preview it, edit the name and description, move it between folders, copy its URL, or delete it. Descriptions are written to help AI features reason about your media; they are private — never shown to message recipients and never publicly visible — even though the asset file itself is served publicly. Existing assets start with an empty description you can fill in at any time.

• Dimensions — exact pixels for images, plus duration for video. Use this to confirm something fits a rich card before you pick it.
• Type — MIME type, useful when troubleshooting a rendering issue.
• Size — file size on disk.

RCS templates have fixed aspect ratios — most notably 1.91:1 for rich card heroes. The asset library tracks the original aspect ratio and warns you in the campaign wizard if the asset will be cropped. There's no in-app cropper; do that in your design tool of choice before uploading.

You can delete an asset only if it's not currently referenced by any campaign in Draft or later. The delete dialog tells you what's in the way. To free up the asset, archive or duplicate the campaigns that hold it.
