Compressing jpg files; Which online tool is better?

Compress jpg files; Which is better?

We needed to place a few banner images on one of our web sites. The high resolution images were of the size of over 2MB. This is not ideal for a home page of a website. So, we decided to try a few image compression tools online.

The Image Compressing Challenge Contenders

We tried three image compression tools, such as, and

The first mentioned compressjpeg gave me a reduction of 72% from the original. To the untrained eye, there is no difference in the quality of the images.

The process was also pretty fast.

On the other hand, tinyjpg failed to upload my 2.5MB file twice and gave me a compressed file the third time.

Guess what, the online image compression tool shaved off 78% from the original image size.

Compressjpg, the third online tool that we tried, took a longer time to process the source image. The first attempt seemed to be a fail.

When trying the second time. File upload happens and there is a message which says the file was converted. But, the download link seemed like a Google adsense link.

So, of the two successful ones, the choice would be for speed and for better compression.

But, wait. There are other online tools like and Of these, seems to be good choice, compressing the original image of size 2.4MB to a size of about 375K. That is cool 85% reduction in size., meanwhile gave a compression of about 71%.

The Image Compressing Champion

Finally, from our analysis of jpeg image compression tools, we found out that the following tools gave us image compression without apparent loss of quality. In order of compression efficiency, they would be,, and

The winner of the compression challenge would be jpeg-optimizer
