What is the difference between "transferred" and "resources" in Chrome DevTools Network tab?

Transferred is the compressed size of all resources. You can think of it as the amount of upload and download data that a mobile user will use in order to load this page. Resources is the uncompressed size of all resources.

Question: Can you all think of better words to describe these two values? We get this question somewhat often.

In addition to the other answers, if you have filtered the results you will see two numbers in one column, first one indicating the size for the filtered requests and the latter for the total size of requests.

For example if you have filtered the results to only display XHR requests and you see 1 MB / 2 MB transferred at the bottom, that indicates 2 MB has been transferred in total, of which 1 MB are XHR requests.
