The Templates Library opens in a new browser tab by clicking on the Templates button in the left menu. Choose from a wide variety of templates to create your own visually appealing content. Scroll through the full list, or select a category to browse its content.
Once you have selected a template, enter the editor to customize it. Most elements have a simple click-to-edit interface. Double-click to edit the text.
Access your designs by clicking on the Your Designs option from the title bar.
Any element in the template can be edited or moved by selecting it and using the built-in tools to rotate or resize it, add shadows and outlines, change colors and textures, and more.
You can use the Undo Ctrl+Z and Redo buttons to reverse or re-apply content changes.
Take some time to play around and familiarize yourself with the template editor and its capabilities.


Raw documents can also be uploaded as content. Emerald converts them to images on the back-end and shows them at the rate you set in options. Emerald can handle PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, and all LibreOffice file types (ODT, ODP, etc).
