Hi everyone, i was having problem with the "Optimize Images" point from the performance test from GTMetrix, i downloaded the optimized versions from there and replaced all the unoptimized images, but GTMetrix keep showing me the same without results, also other performances test recommended me the same point, what i should do? Thanks!
Performance Report for:https://gtmetrix.com/reports/lcdtcorp.com/YGc3AeFN
Try using https://tinypng.com/
the optimization algorithm is very good there and it's free.
You can also use https://www.irfanview.com/ software for optimizing multiple images at once (all images in a folder) - works well if you need to optimize hundreds of product images.
For some clients, we tested a few linux programs which can optimize all the images right on the server in a specified folder but the quality is not as good as the above software so it's worth a bit of extra time required to download, optimize and upload images back to the server.
Hope this helps.
