You can download all the attachments using EWS API and C# . Below is the example given:

byte[][] btAttachments = new byte[3][]; //To store  3 attachment 

if (item.HasAttachments) {
    EmailMessage message = EmailMessage.Bind(objService, new ItemId(item.Id.UniqueId.ToString()), new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments));

    noOfAttachment = message.Attachments.Count;

    // Iterate through the attachments collection and load each attachment.
    foreach(Attachment attachment in message.Attachments)
    {
        if (attachment is FileAttachment)
        {
            FileAttachment fileAttachment = attachment as FileAttachment;
            // Load the file attachment into memory and print out its file name.
            fileAttachment.Load();
            //Get the Attachment as bytes
            if (i < 3) {
                btAttachments[i] = fileAttachment.Content;
                i++;
            }
        }
        // Attachment is an item attachment.
                    else
        {
            // Load attachment into memory and write out the subject.
            ItemAttachment itemAttachment = attachment as ItemAttachment;
            itemAttachment.Load(new PropertySet(EmailMessageSchema.MimeContent));
            MimeContent mc = itemAttachment.Item.MimeContent;
            if (i < 3) {

                btAttachments[i] = mc.Content;
                i++;
            }
        }
    }
}

Above code converts all the attachment into bytes. Once you have bytes, you can convert bytes into your required format.
