In my opinion, all the compression tools did a great job of maintaining quality that I’d be happy with in most cases (unless it’s a photography website where the image quality is the product). Judging the quality of the images is subjective, so you can download all the images and be your own judge! Quality settings will be set to 75% (some tools do not give you this option)Īt the end of this test, I’ll provide you with a link to a zip file where you can download all the images (since uploading them to WordPress and having ShortPixel running on this site wouldn't give a true representation of each image).Keep in mind, all 5 of these services offer some different options, and it will be impossible to have true apples-to-apples comparisons - but I’ll do my best to choose the most similar options across the board. Later in the article I’ll share my thoughts on each of the tools, and I’m glad Bulk Resize Photos is still included, because it’s actually a nifty little tool! The Testįor this (highly-unscientific) test, I’m going to upload four different images into each of the optimizers (3 JPG’s and one PNG with transparency) and see which one gives us the best compression rate. This should have been obvious from the start (doh!), but since I had already run the tests, I figured I’d leave it in the results anyway. Using the suggestions in the group, we ended up with 5 contenders:Īfter running all the tests, I realized that Bulk Resize Photos is the black sheep of this bunch, as it’s not really a compression tool. This week a thread popped up in the group asking for suggestions for a web-based option for compressing photos, and it sounded like a fun thing to test!īelow I’ll take you through the test I ran, and give you my overall thoughts on each of the compression software services. By this point I’ve bookmarked a dozen image compression websites - and for the longest time I’ve used the Optimizilla out of habit.
