Gmail To PDF

A helpful collection of Google Apps Script utilities which allow you to painlessly transform Gmail messages into PDFs.

This handles all of the heavy-lifting needed to preserve all attachments, inline-images, remote images, backgrounds, etc. Also included are a few helpful methods for creating virtual queues within your Gmail labels, using either unread status or starred status as a signifier.

PDF Example

Getting Started

To get started, you can either open the example project, create a copy, and modify it to your liking, or you can create a new Google Apps Script project and add GmailUtils and DriveUtils as libraries by going to Resources > Libraries... and entering the following project IDs:

  • MsE3tErxE9G0z6EMfGmUGqVVaKzeOjMwH
  • MUDdULBfiLdgEZ13bA9paOlVaKzeOjMwH

Alternatively, you can import GmailUtils.gs or DriveUtils.gs into your own project and access the library directly with no name spacing.

Example Usage

Iterate through all starred messages with the label 'Expenses' (up to 5 messages per call), convert each to a PDF, and save them to Google Drive, then unstar each message after archival.

function saveExpenses() {
  GmailUtils.processStarred('label:Expenses', 5, function(message) {

    // create a pdf of the message
    var pdf = GmailUtils.messageToPdf(message);

    // prefix the pdf filename with a date string
    pdf.setName(GmailUtils.formatDate(message, 'yyyyMMdd - ') + pdf.getName());

    // save the converted file to the 'Expenses' folder within Google Drive
    DriveUtils.getFolder('Expenses').createFile(pdf);

    // signal that we are done with this email and it will be marked as read
    return true;
  });
}

Convert the 10 most recent unread messages in the "promotions" category into a single pdf, mark them as read, and email the digest to yourself.

function unreadPromotionsDigest() {
  var to = Session.getActiveUser().getEmail(),
      subject = 'Latest promotional emails',
      body = "here's your unread promotional emails:",
      messages = [];

  // limit this to 10 threads (may be more than 10 messages)
  GmailUtils.processUnread('category:promotions', 10, function(message) {
    messages.push(message);
    return true;
  });

  // convert the group of messages into a single pdf
  var pdf = GmailUtils.messageToPdf(messages, {filename: 'recent_promos.pdf'});

  // email the converted document
  GmailApp.sendEmail(to, subject, body, {attachments: [pdf]});
}
