You can save almost any email as a PDF by using the print/share options built into your email app. Here’s a clear, step‑by‑step guide for the most common platforms.

Gmail on a computer (browser)

  1. Open Gmail and click the email you want to save as PDF.
  1. In the opened message, click the three vertical dots (⋮) near the top‑right of the email content (not the browser).
  1. Choose Print.
  1. In the print window, change the printer Destination to Save as PDF (or a similar PDF option).
  1. Click Save , choose the folder on your computer, and give the file a clear name.

Tip: Use a descriptive filename like Invoice_March_2025.pdf so it is easy to find later.

Outlook on Windows (desktop app)

  1. Open Outlook and select the email.
  1. Go to File → Print.
  1. In the Printer list, choose Microsoft Print to PDF (or Adobe PDF if you have Acrobat).
  1. Click Print.
  1. When the Save Print Output As dialog appears, pick a folder, type a filename, and click Save.

If you use Outlook on the web, open the message, click More actions (⋯) → Print , then again pick the PDF option in the printer list and save.

Apple Mail on Mac

  1. Open the Mail app and select the email.
  1. Go to File → Export as PDF… if available; if not, choose File → Print….
  1. In the print dialog, click the PDF menu at the bottom left and choose Save as PDF.
  1. Choose a folder and filename, then click Save.

iPhone / iPad (Mail or Gmail app)

  1. Open the email you want to save.
  1. Tap the Reply/Share icon.
  1. Select Print.
  1. On the print preview, use two fingers to pinch out (expand) the preview so it turns into a full‑page PDF preview.
  1. Tap the Share icon again and choose Save to Files , Save as PDF , or a cloud folder (like iCloud Drive).

Android (Gmail or default mail app)

  1. Open the email.
  1. Tap the three‑dot menu (⋮) in the top‑right corner.
  1. Tap Print.
  1. In the printer dropdown, choose Save as PDF.
  1. Pick your folder, then tap Save.

Some Android Gmail versions also show Download as PDF directly; if you see that, you can use it instead of Print.

Saving multiple emails as one PDF (mainly Outlook)

If you need a whole conversation or several emails in a single PDF:

  • In Outlook, select multiple emails (hold Shift to select a range).
  • Go to File → Print and pick Adobe PDF or another PDF printer.
  • Adjust the preview if necessary, then click Print and save the combined PDF.

Some add‑ins for Outlook can also batch‑export many emails to PDF with extras like table of contents or watermarks.

Why people do this (quick context)

Saving emails as PDFs is useful for:

  • Archiving receipts, invoices, or contracts for tax or legal records.
  • Sharing an email with someone who doesn’t use the same email service.
  • Keeping a “frozen” copy of an email thread in case the original gets deleted.

TL;DR:
Find the Print option in your email app, switch the printer to Save as PDF , then Save the file to your computer or phone’s storage.
