Mehrdad Reshadi presents Extreme Image Performance without Quality Loss


7:00PM - Meet, Greet & Eat

7:30PM - Main Presentation

Followed by Q&A


 Big high-resolution images look great but are a big drain on web performance. Don’t resort to squashing image quality for speed. Modern browsers, image formats and best practices offer performance plus high quality. Topics include progressive and interlaced rendering, quality levels, new formats like Webp and JPEG XR, and how to interleave download and rendering across images on a page for speed.

We will cover the following topics:

- Understand JPG and PNG formats and the tradeoffs and differences in time to display for regular, progressive, and interlaced rendering

- Best practices for properly adjusting quality levels, safe removal of metadata, and lossless compression

- Understand the benefits, drawbacks, and major features of new image formats from Google (Webp) and Microsoft (JPEG XR)

- Mechanisms to interleave downloading and rendering of images across a page with multiple images or single images with splits.
