JPEGmini works most efficiently on JPEGs saved directly from digital cameras. JPEGmini is a new JPEG recompression algorithm that shrinks existing JPEGs by up to 5 to 6 times smaller than their original size, without any change in appearance. This enables us to apply the optimal amount of compression to each photo. it imitates the qualities of the Human Visual System (HVS) very closely. Basically we developed a quality measure that is perceptual, i.e. Our technology can identify what is the optimal compression that can be applied to each photo, so no artifacts will be visible at 100% zoom. (=very high quality), and this ensures that almost all photos will not have any artifacts, but at the cost of very large file sizes. The reason is that digital cameras don't have "smart" compression algorithms, so they just set the compression level to a very low number Gill: Yes, our software works best for original JPEGs from the digital camera.
WSO: It looks like your software works best from original JPEGsįrom digital cameras, correct? Why is that?

To lower quality levels as well, and we may expose this functionality inįuture versions of the website or in the offline products. However, our technology does enable compressing Gill: Our web service currently does not support setting the compression level,Īs we want to create the best quality photos which are perceptually WSO: Do you offer a way to adjust the level of compression? Including offline software such as a desktop application or Photoshop plug-in, and Gill: We are considering other formats for implementing our technology, Gill: - JPEGmini currently we only supports JPEG images. WSO: Do you accept images other than JPEGs? Say TIFFs? Gill: We iterate using our own perceptual quality measure, which converges veryįast, and also do some clever stuff with the JPEG encoding itself. WSO: How does JPEGmini work? Do you iterate? We talked to Dror Gill, the CTO of ICTV about JPEGmini. Bottom line, we were able to reduce JPEGs saved directly from a digital camera from 3 to 6 times smaller (see Figure 1).įigure 4: JPEGmini Results from a Smaller Version of Same Photograph Interview with CTO Dror Gill of ICTV
To test the service, we tried optimizing images saved directly from a digital camera, and from scans from slides.

You can upload single images to optimize (or register to upload entire albums and export them to Picasa and Flickr) and download the results.

You can try JPEGmini out for yourself as a free service at. Rather than using an arbitrary amount of compression as in Photoshop (low, medium, high), JPEG mini applies the optimum amount of compression for each given image, while maintaining existing perceived visual quality. This features enables JPEGmini to apply the optimal amount of compression to each photograph. ICVT developed a perceptual quality measure that imitates the qualities of the human visual system. JPEGmini works by iteratively reoptimizing existing JPEGs using their own perceptual quality measure. In this article we test the new service, and interview the CTO. The results, as you will see below, are smaller files that look visually identical to the original images. The patented algorithm developed by ICVT allows JPEGmini to compress images just below the level where perceived artifacts appear. Developed by ICTV, an Israeli startup company, JPEGmini works within the existing JPEG standard to optimize the size of JPEGs for faster downloads and lower storage costs. JPEGmini is image optimization technology that reduces the size of JPEGs by up to 5 or 6 times their original size, while maintaining resolution and perceived quality. WSO tests the free service and interviews the CTO of ICTV. Summary: JPEGmini is JPEG optimization software that reduces the size of photographs by up to 5 or 6 times, while maintaining their visual quality.
