Over 64,402 registered users choose Image Compressor.

Here's why:

"Options, speed of product, price, and easy of use"

April Grunwald, Rochester, USA.
"After testing over 15 different image software programs I found only one compressor that I would highly recommend... So here’s my pick – Image Compressor 2008. I found this software to be well thought out providing a professional solution and superior resolution at a great price."

Tom Jones, Webitgeek, Lake Oswego, USA.
"Image Compressor Lite does everything I need it to do. Pictures out of today's high-megapixel cameras are just too large to email to friends, and Image Compressor Lite prepares all of my pictures at once for emailing with its batch mode. Excellent!"

David Roe, Helotes, USA.
"The quality is great. For a similar file size (to your compressed file) from Photoshop I got the worst quality (0) JPEG (a really bad quality). Equal quality I think I got with (5) JPEG but with larger file by 40% that means better overall result for your compressor."

Apostolidis Dimitris, Thessaloniki, Greece.
"I work in IT as a consultant and developer, and also know my way around photoshop ... The result of your picture is very very nice, keep up the good work."

Lars Jensen, Tokyo, Japan.

Image Compressor uses a proprietary image compression algorithm called Digital Eye.
Learn how Image Compressor and its Digital Eye outclass the legacy JPEG compression technology.

The Old Legacy JPEG Compression Algorithm

To date, JPG is the worldwide standard of saving picture in compressed format. Despite of the quality problem it has, people and industries still prefer JPEG because of its small size and good enough quality.

Legacy JPEG compression takes out a bitmap image, and performs several phase to achieve best compression ratio.
This old JPEG compression method itself doesn't really analyze the picture. Instead it uses numerical data to compress the image. This is why old JPG creates artifacts, blocky image and other problems with it.
Let's have a look at how the old JPEG compression method works:
  1. Color space transformation
    JPEG converts RGB bitmap to Y Cb Cr color space.
  2. Downsampling / Chroma sampling
    Humans can see better detail in the brightness of an image (the Y component) than in the color of an image (Cb and Cr components). This is where the old JPG starts to create distortion.
  3. Block splitting
    Each channel splits into 8x8 pixel blocks. The old JPG fills in incomplete blocks with dummy data.
  4. Discrete cosine transform
    This where numerical, frequency domain takes part.
  5. Quantization
    Human eye is good at seeing small differences in brightness over a relatively large area, but not so good at distinguishing the exact strength of a brightness variation. This allows old JPEG to reduce the amount of information in the high frequency components.
  6. Compress the data
As you may already notice, step 2-5 above make the picture distorted, but can be compressed better in the 6th step. This is the major problem people have to face everytime they use the old, legacy JPEG compression.

Let's see the comparison below:
Original lossless image
Original PNG image.
File size: 75,315 bytes
Compressed With Maximum Quality
JPG Compressed by other software. Maximum Quality
File size: 40,964 bytes
Compressed With Low Quality
JPG Compressed by other software. Low Quality
File size: 3847 bytes
That is very much other softwares give you. Other softwares mistakenly ruin your hardwork by trying to compress as much as possible until the image quality turns so bad you don't want to look at it.

The New Digital Eye Method

We all understand that JPG is the standard format. So, instead of creating a proprietary image format which can't be opened by other software except from the developer itself, Image Compressor uses the same JPG file format.
The difference that makes Image Compressor outperform the competition is the algoritm to compress the image. That's the Digital Eye. Same JPG format but compressed using different method. This makes the compressed image openable by other softwares and device.

Digital Eye works very much like human eyes and brain (That's us).
Let us explain in the simple way...

Imagine you are looking at an object, say your mouse.
Digital Eye takes a snapshot of the mouse and keep it in the memory. Now, move left a bit, and take another look at the mouse. Again, Digital Eye takes the snapshot and remembers it. Move right, and take another look. Digital Eye also keep the snapshot from your current position.

Now we remember 3 pictures of your mouse. Digital Eye artificial intelligent algorithm decide which parts from those 3 pictures are important. Based on the level of importance, Digital Eye renders and then compress the image.
And that's about it! Now look at the result below:
Original lossless image
Original PNG image.
File size: 75,315 bytes
Compressed With Less Aggressive
JPG Compressed by Image Compressor. Less Aggressive
File size: 29,068 bytes
Compressed With Very Agressive
JPG Compressed by Image Compressor. Very Aggressive
File size: 29,068 bytes
Digital Eye knows that the hats, clouds, sky, and background are important. Digital Eye preserve the detail on them, and compress the image. You still can read the word "Bahamas" in the yellow hat!
Image Compressor and its Digital Eye compress your photos beautifully.
Other software can only compete with the quality Image Compressor produces by adding more "dummy" data on the file and creates larger file.
