If you take a look on the Internet, it becomes quite clear that most pages contain attractive images. They can be illustrations, graphics, icons, or photographs. Focus on your images when you want to optimize your website’s content or the sites you are creating for customers. With a few simple adjustments, those pictures can boost your ranking and increase web traffic.

Exporting images using favourite graphics software is something many of us do regularly.

We fixate on the image’s preview, cautiously adjust the quality, and optimize the settings. We tweak until the file size and quality are as perfect as they can get. A lot of people use the “Save for Web” feature to export images. This specific tool can help users to produce excellent GIF, JPEG, or PNG format images. After being careful and meticulous throughout the entire process, you would think that every picture will be perfect. Unfortunately, that is not always the case.

We all know how frustrating it is when you have to wait for a website to show up after clicking on the URL. Why does it often take longer than it should? Browsers need to download a lot of data. It keeps users waiting. The longer it takes, the more frustrated they get. Eventually, they click away. You can prevent this by using a number of popular tools created specifically to optimize images to the fullest.

With such an abundance of choices, which graphics editing software should you use for your image optimization projects?

Image Optimization Solutions

Many of today’s image optimization tools can be used by professional web designers as well as Internet fans trying to enhance their personal site. Install at least one popular optimization tool, because one is better than none at all. The goal of using technology is to speed up the website, and keep visitors satisfied. Research your options, as quite often, some image quality is lost when shrinking the size and download time of GIF, JPEG, or PNG picture files. If the loss of quality is too noticeable and unacceptable to your work standards, move on to another tool. Collect recommendations from other designers.

Image Optimization Tools Recommendations

Always aim for the biggest gain, which can be achieved by selecting the right tools. Each image optimizer has its own set of techniques to deliver impressive illustrations. Combine several applications for the most amazing results. Check out the following tools:


image optim

Use ImageOptim when you want to load images faster and take up less disk space. This tool works by finding the best combination of compression parameters. You will not have to worry about colour profiles and unnecessary comments when publishing your enhanced images on the web. ImageOptim is also ideal for making iPhone/iPad and Mac applications smaller.

image alpha

Drag a true-colour PNG image into the main screen of the image minifier. Small images should be converted immediately. If an image is too large, the progress spinner should be visible for a few seconds, and complete the shrinking process. If the quality is not satisfactory, select between Median Cut and Posterizer compression, and try the Dithered mode. Reduce the number of colours if you still want the photo to be smaller. ImageAlpha stands apart because of its unique conversion method of PNG24 to PNG8. The savings are many times bigger than when utilizing other popular PNG optimizers, like TinyPNG and Another benefit of this tool is that the conversion continues to maintain alpha-transparency in all browsers.

Advpng or AdvanceCOMP

Advpng has an excellent speed/compression ratio. The main purpose of this tool is to recompress png files to the smallest size possible. The strategies this utility uses include removing ancillary chunks, concentrating IDAT chunks, and using 7zip Deflate implementation. AdvanceCOMP is a collection of recompression utilities for .PNG snapshots, .ZIP archives, .GZ files, and. MNG video clips. It allows users to modify an already-compressed file, in order to reduce the file-size by optimizing the condensed image, in addition to recompressing snapshots, rom, and clip collections of emulated games.

jpeg mini

JPEGmini photo optimization technology can reduce the file size of JPEG photos by up to 5 times, all while preserving the perceptual quality and resolution of the original images. The savings are remarkable as this image recompression technology allows you to maximize the storage of photographs on your computer’s hard drive and on online photo service accounts. It is also easier to email images and upload them faster to the Internet. The fact that JPEGmini files are in standard JPEG format is another great advantage. Images can be viewed and edited by any existing browser and photo software.

PNG Quant

Are you looking for a new command-line utility tool with an image quantization library for converting quantize and dither 24/32-bit RGBA PNGs down to 8-bit RGBA-palette PNGs (or smaller)? PNGquant conversion can reduce file sizes up to 70 percent, all while preserving full alpha transparency. The adjusted images are still compatible with all of today’s key web browsers. Another advantage of this tool is that the pictures have a better fallback in IE6 than 24-bit PNGs. In conclusion, expect high-quality palette generation by combining vector quantization algorithms. The shell scripts, software, and GUIs are easy to integrate, and you have access to an exceptional adaptive dithering algorithm that limits image noise. Large amounts of images will be processed faster, even the color mapped ones.
