TinyPNG has a superior interface that allows you to drag and drop up to 20 images and it returns a compressed version of each image that looks like the original.
Dynamic Drive shows you up to 9 versions of your image, varying in compression rate and quality. The nice thing is, you can pick the image that is “good enough for you”. Unfortunately, you can only compress 1 image at a time and only up to 2.86 megabytes per image.
I decided to give each a try with this un-optimized image.
Dynamic Drive gave me this long list of choices, varying in quality and size. The first image is the unaltered version and the rest progressively reduce quality, but improve compression.
This is great if you are compressing a small number of images and want to see various results so you can choose the best combination of compression vs. quality.
TinyPNG doesn’t show the compressed image on-screen, and generally the image compression errors on the side of higher quality.
The intent is to give you the highest compression they can, without degrading the image quality too much. They call it loss-less compression and you can see from the screenshots below, it reduced the image size by 34% and the quality remains high.
A Third Option
Would you like to have the higher compression offered by Dynamic Drive and the great quality and ease of use offered by TinyPNG? And all without file size restrictions? Let me show you how.
My Website Analyzer offers a drag and drop interface (or file selector), no limits on file size, and you can compress up to 50 images at once. Best of all, you get great compression with great quality. Check out the results below.

Below is 4 images. The first is the original image, its file size is 103 kb. I’ve compressed the second image with TinyPNG and it’s 95.7 kb. I compressed the third image with GrowthHow’s image compression tool and it’s 56.68 kb, and the fourth image with Dynamic Drive’s image optimizer and it’s 55.9 kb. Can you tell the difference?
