Reducing PNG size in published output?
May 24, 2017
Hi! Question for this wonderful hive mind:
One of our clients is experiencing issues with their course being slow and laggy in their LMS and they say it’s due to the large size of the PNG files embedded within the course. We’ve never heard this issue before from any other client (and 90% of them receive this exact same course), and to resize the HUNDREDS of images within the course would take WEEKS. I can’t even imagine the amount of work going into that. So we did some republishing tests to see if lowering the overall image quality upon publish would change the PNG sizes….. the overall course size was brought down but the PNGs themselves were not. Do you know if the smaller overall file size would help with the bandwidth issues they’re having, even if the individual PNGs are not any smaller?
Is there some simple way to mass-resize the hundreds of PNGs used in this course without having to do it individually? (I’m sure there is and I just haven’t thought of it or am not aware of it.)
