The web’s growing complexity has made for even more complex metrics. Web performance—with its dark artistry—demands the interpretation of Gordian data and is legible only to the erudite. The most comprehensible metric remains the page weight. It continues to grow at an alarming rate, robbing mobile users of precious data and destroying user experiences worldwide.
2017 marked the 10-year anniversary of the release of the iPhone. The iPhone, along with other smartphones, brought a rich web experience to a diminutive screen. Ten years into the smartphone era, our media consumption is growing at an alarming rate, increasing page weights along the way. Optimize Prime, a web superhero, goes after the main persons of interest in these misdemeanors: image formats. This big band of bullies has been barging into your browser, bringing nothing but bad news.
Henri-R Brisard discusses image formats, their impact on browsing from a rendering to a UX perspective, the tools and processes in place to address their mismanagement, and the reasons developers must exercise vigilance in a growing and worldly audience of users.
Henri-Robert Brisard is a developer who spends his time proselytizing performance culture and best practices. You can often find Henri coprogramming meetups, including the Toronto Web Performance meetup, or reading the latest research docs and case studies. Otherwise, he’ll be riding track bikes, tooling with music production software, or encouraging devs to run or walk a 5K.
