The easiest way to transfer Gmail emails into a desktop app is to export Gmail to MBOX. This format keeps each email exactly the same as in your Gmail account. All attachments and inline images remain untouched. You can choose specific labels or download your entire mailbox. The exported MBOX file can be moved or imported into many email programs. It is a reliable choice for creating a personal backup. Simple steps make the process smooth, even for non-technical users. It works well for migration, offline access, and email storage.
