Whether you're working with JPGs, PNGs, GIFs, Word documents, Excel spreadsheets, PowerPoint presentations, or PDFs, multiple files can be uploaded at a time from your computer and stored in your Library to add to your campaigns later.
When you upload a PDF into your Library, a PNG image of the first page is automatically created. The image can later be inserted into your email and linked to the full document. Word documents can be converted to PDFs before you upload them to auto-generate a thumbnail image.

Once your files have been uploaded, you can use our image editor to enhance your images before adding them to your campaigns, insert a link to your document in a campaign, or turn a thumbnail of your document into a clickable image.
