Diigo on Chrome

As some of our users may have noticed, we recently have had some issues with our Google developer account. This caused all of our extensions on the account, including the “Diigo Web Collector”, “Quick Note”, “Awesome screenshot” and some other extensions to be unavailable on the Chrome Store. We are not 100% sure of the cause for this action, as Google only provides developers with a vague reason such as “Code visibility” issues. We think it’s due to some third party integration in “Quick Note”. In fact, most of the responses on their side have been automated, making the process of retrieving our original developer account a long and tedious task. We are still in communications with Google and will do our best to retrieve our original account that has years and years of positive reviews and about 5 million users. For now, we have set up a new developer account under for our users to be able to continue to use and update Diigo on Chrome.

Please refer to our Chrome Store link to install our extension :

We will keep you updated on the process of our original account retrieval. In the meantime we are still 100% dedicated to providing our users with the best learning tool, and will continue to improve Diigo’s user experience and functions. Leave a comment if you have any feedback for us or input on how we can further improve your learning experience.

Thanks for your support!

Annotating PDF Docs with Diigo – A Tutorial  

There are two different methods with which you can annotate a PDF doc with Diigo.

(If you don’t want to read the tutorial,  try the PDF annotation feature directly.)

Mehtod 1:   Annotate a PDF doc by first uploading it  to the Diigo website

  • Step 1:  Upload a pdf doc to your diigo library in “My Library” page;
  • Step 2: Open the uploaded PDF doc in your browser, and you should see a toolbar on top of the doc;
  • Step 3: Select text to highlight or add a sticky note. Your highlight and sticky notes on the PDF will be saved in your Diigo library.


Method 2: Annotate a PDF using the  Diigo browser extension (available for Chrome and Firefox only, and the instructions below are for Chrome)

  • Step 1: Open an online PDF doc,within Chrome, with the Diigo extension installed;
  • Step 2: Click the  “Annotate” button at the upper right corner of the opened PDF doc (see the first screenshot below). The doc is then opened again with a toolbar on top (see the second screenshot below);
  • Step 3: Select text to highlight or add a sticky note. Your highlight and sticky notes on the PDF will be saved in your Diigo library.


How to Annotate and Clip non-text PDF Doc

If a PDF doc is in a form of an image, then you cannot highlight any text, but you can use the screenshot feature of of the Diigo extension (chrome and firefox) to capture or crop the image, and then annotate it as a screenshot.



Export an annotated PDF doc

The annotated PDF doc can be exported.  However, due to some tech limitation, after being exported, in-line sticky notes are invisible  for mac users who use preview as their pdf reader.

Due to the complexity of the PDF format and the compatibility issues for different browsers and browser versions,  Diigo PDF annotation may not work perfectly for every PDF file. If you experience any issue,  please do let us know.
