Do you want to save an email from Gmail to read it offline? Every modern browser makes it easy to "print" an email to a PDF file.
How does it work
Both Windows and Mac have a built-in PDF printer. Any files you send for printing to this virtual printer are converted to PDF. PDF files retain the formatting of documents. These files actually print, unless you decide to print the PDF file from a real printer later.
How to save an email as a PDF
Because almost all browsers have print support, you can use Chrome, Edge, or Firefox to print your emails in PDF. To get started, open your favorite browser and visit Gmail. Sign in to your Gmail account.
Then open the email you want to save as a PDF. In your email window, click the menu with the three dots in the upper right corner and select "Print".
In the "Print" window, click the drop-down menu next to "Destination" and select "Save as PDF". If necessary, give the settings you want such as layout and margins.
When you are ready, click "Save" to start creating your PDF.
You will see the save dialog box. In this window, enter the name of your PDF in the "File name" field, select a folder to save your PDF and click "Save".
Your email will be saved as a PDF file in the folder you specified. Too easy. You can basically "print" as many emails as you want in the same way.
