Reduce file sizes for images in WordPress including NextGEN, GRAND FlAGallery and more using lossless/lossy methods and image format conversion.
Try this for starters: http://ewww.io/2014/12/05/pagespeed-says-my-images-need-more-work/
Yes, but only if the optimized version is smaller. The plugin should NEVER create a larger image.
No, we leave that to other plugins like Imsanity.
The lossy optimization using the EWWW IO Cloud service will determine the ideal quality setting and save even more space. You cannot manually set the quality with this plugin, but Imsanity (and many others) will do that if you really want to. But you should REALLY try EWWW IO Cloud first.
I've tested it on Windows (with Apache), Linux, Mac OSX, FreeBSD (8 and 9), and Solaris (v10). The cloud service will run on any OS.
Lossless optimization is done with the command jpegtran -copy all -optimize -progressive -outfile optimized-file original-file. Optionally, the -copy switch gets the 'none' parameter if you choose to strip metadata from your JPGs on the options page. Lossy optimization is done using the outstanding TinyJPG and JPEGmini utilities.
There are three parts (and all are optional). First, using the command pngquant original-file, then using the commands pngout-static -s2 original-file and optipng -o2 original-file. You can adjust the optimization levels for both tools on the settings page. Optipng is an automated derivative of pngcrush, which is another widely used png optimization utility. EWWW I.O. Cloud uses TinyPNG for even better lossy compression than standalone pngquant.
Using the command gifsicle -b -O3 --careful original file. This is particularly useful for animated GIFs, and can also streamline your color palette. That said, if your GIF is not animated, you should strongly consider converting it to a PNG. PNG files are almost always smaller, they just don't do animations. The following command would do this for you on a Linux system with imagemagick: convert somefile.gif somefile.png
That's not a question, but since I made it up, I'll answer it. See these resources: http://developer.yahoo.com/performance/rules.html#opt_images https://developers.google.com/speed/docs/best-practices/payload#CompressImages https://developers.google.com/speed/docs/insights/OptimizeImages Pngout, TinyJPG/TinyPNG, JPEGmini, and Pngquant were recommended by EWWW IO users. Pngout (usually) optimizes better than Optipng, and best when they are used together. TinyJPG is the best lossy compression tool that I have found for JPG images. Pngquant is an excellent lossy optimizer for PNGs, and is one of the tools used by TinyPNG.
