EWWW Image OptimizerĪ WordPress plugin that automatically compresses uploaded images. By utilizing several Open Source programs like PNGOUT, AdvPNG, Pngcrush, OptiPNG, JpegOptim, jpegrescan, jpegtran, and Gifsicle it has lots of muscle for jpeg compression.įor Microsoft Windows users, there are similar apps, like RIOT, but I haven’t tried it.
JPEGMINI VS IMAGEOPTIM FOR MAC OS
ImageOptim is a popular (and free) image optimizer for Mac OS X. But if you have to send large photos with the quality of the original still intact, this is the obvious choice. And it seems like it’s a good match for some smaller images as well. I’ve included lower resolution pictures just out of curiosity. This is a tool primarily for compressing large size images and does a fantastic job of it. JPEGmini is an excellent image compressor application on Mac OS X. I tried to take different kind of images, where some contain a lot of details, and other with less, to see what kind of effect that has on the image compression result. I’m not a big fan of jpeg artifacts, but you could get away with much lower quality setting depending on the picture. I exported all the pictures from Adobe Lightroom 4 as jpg with a quality setting of 80, which is the one I usually use when uploading to my blog, Flickr or 500px. I’m concentrating on testing jpeg files here, and do a followup article later with results for optimizing PNG files. All applications tested claims not to lower the quality of the image. But which one works best for posting images on a website? I was curious, so I took the tools I usually use and put them through the compress photo function. There are several JPEG image compression tools available that takes a jpeg file and reduces the size of the photo without altering the quality.
