Heart Best Image compression software
I would like some advice on the best piece of image compression software people recommend? I did have a piece of software but I can't remember what its called and now on a new machine.

I would be really grateful for any help on the best one to use. My page speed tests keep telling me I need to compress some images. I have ran them all through tinyjpg.com but still saying can get more out of them.

RE: Best Image compression software
Have you tried this site? https://shortpixel.com/online-image-compression

I've seen those compression messages as well though. Even re-edited some jpgs because it was reported they weren't progressive. Made them progressive through Photoshop, uploaded, and still see same message.

RE: Best Image compression software
You could try one of these software for image optimization:
  1. ImageOptim: This tool is now being offered as an API. I don't know if it is free for any level of use.
  2. Mozjpeg: This is the actual code used behind imageoptim. You could install it on your build / publishing server. As a part of the CMS publishing work flow, you could run the image through mozjpeg/cjpeg commands to reduce quality / losslessly compress the image. (This will work only on JPG images).
  3. Pngcrush: This software works only on PNG images. Again this is a command line tool and the actual code behind ImageOptim's PNG optimizing software. You could build optimizing PNG images into workflow thoug the software.

If you are looking for online tools, you can try https://compressor.io/. It doesn't expose the algorithm being used for the image compression. However, it is one of the better tools that I've seen for online use.

From these, I would reccommend Mozjpeg, it works really good, but like mentioned before it ony works with jpegs.

I've looked into this a bunch and haven't ever found anything as good as tinypng. They have a server side solution which is very affordable as well.

RE: Best Image compression software
I'd suggest that you try the WebP image format developed by Google for lossless and lossy compression of images. This page contains more info, including fallback mechanisms as not all browsers support it yet - http://caniuse.com/#search=webp.

You can actually preview your site with WebP images - just do a WebPagetest run with Chrome and 'Enable Data Reduction' checked in the Chrome tab. This way the reponse will go through the Google Data Saver proxy which compresses all images using WebP. You can then compare the size of your images.

RE: Best Image compression software
I just saw that yesterday Google announced a new jpeg encoding - Guetzli which produces JPEGs that are "35% smaller than currently available methods". It doesn't introduce a new file format (like WebP) so no browser support issues. Maybe it's worth checking out.

I find that IMAGIFY (https://imagify.io) has the best image compression versus image quality for my purposes. It is most easily used in Wordpress sites as they provide a plugin.

Imagify also make available an API for custom development environments.

Free and very low cost Premium plans are available.

Best of luck!
