| Description | PST files are intended for storing mail elements on PCs, which include mail folders and their content. PST stores copies of these elements locally, and they are supported by well-known and common applications, particularly Outlook. Users can get to their emails even when there is no stable IT connection. PSTs can be accessed via whatever version is installed on your PC. Files saved in later versions use Unicode can hold a lot more data than those created in earlier ones, which use ANSI. Users who prefer not to use this program may choose to convert messages to other formats and open them in third party utilities. |

Lawyers, compliance officers, and IT teams use PST-to-PDF conversion to archive Outlook email as fixed, non-editable documents that can be opened without any email client.
PST (Personal Storage Table) is Microsoft Outlook's proprietary archive format for storing emails, contacts, and calendar items in a single binary file. It can only be opened natively in Microsoft Outlook on Windows, making it inaccessible to anyone without a licensed copy. PST files often grow to several gigabytes and cannot be previewed without the full Outlook application.
PDF (Portable Document Format) is an ISO-standardized format that renders documents identically on any device and operating system. It is the default format for sharing documents that must not be edited, including contracts, reports, and archived correspondence. PDF viewers are built into every major OS and browser.
