Hello can someone help me, am looking for the best software that can compress MB image to KB and still retain it’s quality.
What image format is the image in? How many MBs is it? What is your target size etc.
“…retain its quality” can be a bit subjective depending on what you mean by that. The only way to compress a image and retain 100% of its quality is to use a lossless compression for the respective format. If you are looking to retain visual quality where most who look at the image would notice little or no difference, then you may be able to achieve you goal. Sometimes switching from one format to another like PNG to JPEG will help. Also with JPEGs especially quite large images saving with “progressive” encoding rather than standard, will often get you smaller end file size.
The image content itself can have a lot to do with how much and how well you can compress an image without much visual change. A image with lots of detail and tonal changes such as trees, will be harder to compress significantly than a image with lots of flat even tone areas such as architecture.
The best compression tools are not necessary 1 click solutions. There are a variety of techniques that can be used to optimize an images compression. One technique that can be used is selective blur. Some images can even benefit from such a technique by putting more emphasis on the subject. An example of this would be a image with a main central subject with a detailed background. If a blur is applied in some way to the background, if even slightly, you will see a fair boost in compression.
Another technique is to use a posterization filter on the image adjusting the percentage just to the point where it begins to pass the desired quality and then backing it off. This works because it reduces the tonal ranges (not sure if that is the correct term) in the image, which also reduces the amount of information that needs to be compressed. Similarly you can sometimes reduce the number of colors in your image, e.g. from 32bit to 16bit or 16bit to even 8bit with very little visual change and a fair savings for the end file.
You can use these techniques and others that are even more labor intensive in applications like Adobe Photoshop or competing products. If you are hoping for more of a simple click solution I have seen many web developers in particular tout Kraken.io and Caesium but I personally have only played with Kraken a little and found I can still usually produce higher compression and better quality out of Photoshop. I have also used Corel’s Paint Shop Pro for compressing images using the same methods and results are very close to the same.
Hello Friend the image sizes are between 2 - 6 MB because they are taken directly from photo camera, so I want to reduce them to at least between 50 - 100 KB.
Can the software compress the image and still retain it’s quality?
What will you do with the compressed image? How will it be used? And what are the pixel dimensions of the original image?
There are very few images of that size that can be compressed to between 50 and 100 KB and retain good quality. Extremely simple photos, like an image of a clear blue sky might compress that small, but anything with any detail won’t without introducing very noticeable compression artifacts.
One of the best ways to apply jpeg compression is with Photoshop’s “Save for web” feature. It enables you to adjust a slider bar to see what the image will look like with varying amounts of compression.
Yes. This works well.
Hello Friend the images are products that will be uploaded in an online store.
Hello Friend, the images are products that will be uploaded in an online store.
You can probably get away with reducing the dimensions of the images for start
Not a lot of info here.
Are you just using the product shots as static images or is there a zoom function on the website to see the items close up?

You haven’t supplied enough information to answer your questions with any certainty. However, it seems unlikely that you would need any online product images that, in an uncompressed format, would weigh in at 6MB. If you reduce the product images to a standard size — maybe 2MB — then compress them, you’ll be better off.
There’s also the issue of how many images per page will be displayed. If it’s just one product image, you won’t need to compress it as much. If there are multiple images per page, they should be smaller to keep the total download size of the pages to reasonable levels.
Depending on your e-commerce software, there could also be the option of initially showing only smaller thumbnail views. When potential buyers want to see larger, close-up versions, they would click the thumbnail to download and view the larger, more detailed version in a separate window, popup, modal, overlay or whatever.
