Have you exported Google Vault data and are stuck with the MBOX files? The guide here will give you the best workaround to convert Google Vault Chat MBOX files to PDF format. By converting the files to PDF, we are making the files most accessible globally without any issues.

What are Google Vault Chat Files?

Google Vault is Google Workspace’s archiving or eDiscovery solution, mostly used by organisations to search, export emails, chats, and Drive files. After you export Google Chat data from Google Vault, you receive it in MBOX format. MBOX is a standard Unix-based mailbox format that stores multiple messages in a single text file.

MBOX files are a widely accepted email archive format, but users face some challenges when working with them. You cannot open the file by double-clicking or print it directly.

That is the reason why converting Google Vault Chat MBOX files to PDF is crucial for the legal team, IT Admin, etc. Let’s find out why convert to PDF instead of other document formats.

Why Convert to PDF for Google Vault Exports?

PDF format is the most preferred file format for document archiving for several important reasons.

  • Universal readability: PDF can be opened on any device, OS or browser without the requirement of any software.
  • Print-ready: PDF files can print the document as it is. It is critical for the court’s legal purpose.
  • Tamper Free: We can make the PDF files digitally locked, making them legally reliable for evidence.
  • Long-term Archiving: PDF files follow an ISO standard designed for long-term document preservation. It can embed metadata like author, date and document properties.
