The real, official (supported!) project lives here: github.com/ausi/respimagelint

But you can install this forked (unsupported!) bookmarklet by going here: eeeps.github.io/respimagelint

I forked the original in order to resize tested viewports one px at a time (the original bookmarklet resizes in 20px steps). This makes the sizes that the tool suggests slightly more accurate, at the cost of making the bookmarklet 20× slower.

RespImageLint is a bookmarklet that checks images of a webpage against a list of common mistakes and best practises.

Go to eeeps.github.io/respimagelint, add the bookmarklet to your browser toolbar and run it on your website.
