Update 2020-10: I don't know what Google did, but Google Web Light doesn't seem to work anymore!
As of the second week of October, 2020 http://googleweblight.com/i?u=[your_website_URL] (which is the format specified in Google's documentation)
now redirects you to the website URL you entered. The help document about Google Web Light has not been updated. It appears that Google has discontinued this service (as they have done with so many other products that people relied on in the past). If you have any further information to share, please email me at the address below.
This is a simple form to view any URL in Google Web Light's low-bandwidth view. Since the old Google mobilizer is no longer available, it forwards all urls of the format http://google.com/gwt/x?u=[URL] into a URL of the format https://googleweblight.com/?lite_url=[URL]&f=1 This form will stick your URL into Google Web Light with the f=1 parameter added, which causes Google Web Light to replicate the old mobile optimized view as closely as possible.
