So to test again Pixelmator, images were opened, resized and then exported as Jpeg twice. JpegMini has a default resize to 960 * 720 pixels, not enabled as default, with no other settings other than to where you want to save the new files. So to test this I’ve pulled a selection of photos with varying colors and details for resizing and compression. It takes a while to trust JpegMini to do the right thing as there’s no preview window, no quality settings just simply drag and drop the image. I’ve now realised I’ve been making a mistake for the longest time at pulling an image into Pixelmatr, applying a resize, then exporting the file with the default settings looking at the small preview window trying to guess the right balance of size vs quality. blooming when you compress images with their app. Thanks to this more probing way at looking at the whole picture JpegMini claims to have less artefacts, color blow out and that annoying blockiness from things being over compressed. What this means in simple terms that JpegMini sees different shades of red as just that, different shades whereas programs like Photoshop tend to group reds in a more generalist sort of way and then clump them together. Jpeg mini is a small, easy to use program that shrinks down your jpeg image but proclaims to loose as little amount of the image detail as possible, all down to their own algorithms that look at all of the pixels in an image than taking just an average mix. This is something I only found out thanks to the Mac And Forth podcast so I take no credit for this finding but JpegMini turns out to be a bit of a gem. Turns out this isn’t the case as theres more than one way to compress a jpeg for the best results If you used photoshop or Pixelmator and hit the file, export as jpeg function you could think that the jpeg defaults are set to optimal levels. JpegMini helps do just that, providing the optimum balance between compression, quality and clarity. There’s several ways you can speed up your website, use a CDN, get a better host but none of that is going to help unless your images are properly optimised.
