Join Morten Rand-Hendriksen for an in-depth discussion in this video Manual image optimization, part of Developing for Performance: HTTP/2.
- [Instructor] Optimizing images for the web…can be done manually or you can automate the process…using Command Line and other tools.…However, for best optimization results,…it's a good idea to combine manual and automated processes.…For manual image optimization of JPEGs, in particular,…you can go through a four step process.…First, blur unnecessary areas by introducing high bokeh…or shallow depth of field and make sure that unnecessary…components are removed from the image…to make it as uncomplex as possible.…
Next, size the image to match the largest possible area…it will be displayed in on the final site.…Here, you also have to take into account…high resolution displays.…So, you have to size it for two x,…three x, and maybe even four x displays.…Third, export the image with as low quality as possible…as long as you are not losing visual acuity or quality.…This can be done using Photoshop's export manager…where you can set and toggle the quality output…and see what happens when you reduce the quality.…
Just keep in mind, if you reduce the quality enough…
