#LOSSY PNG COMPRESSOR CODE#

On the other hand, the biggest disadvantage is that this is achieved with some loss of quality - even though, as we explain, it’s almost imperceptible. The biggest benefit of lossy compression is that it significantly reduces the size of the image file. Benefits, Advantages, and Disadvantages of Lossy CompressionĪt this point, you may be wondering what the pros and cons of lossy compression are. This is leveraged for image compression as we compress some colors more than others. Our eyes have a different sensitivity to different colors. Images are great candidates for lossy compression because of the way our eyes work. However, our human eyes do not notice the difference between JPEG, GIF, PNG, or other formats. The most common lossy image formats are JPEG and GIF.

The truth is, we use lossy image compression all the time on the web. In other words, no user will notice that your images are compressed (unless you compress the same image over and over). For other data types, such as images or video, you can compress it and present an “approximate” representation of the original data without losing its meaning.

#LOSSY PNG COMPRESSOR CODE#

One piece of bad data and your code can break. When optimizing data such as source code on a page, it’s critical to ensure that the compression doesn’t alter the code. The usual irreversibility of lossy compression begs the question: why should you use it? You’re in luck: With the Imagify WordPress plugin, you’ll be able to revert to your original pictures if you are not satisfied with the results. Once you have compressed an image this way, you can’t go back. If you’re asking if lossy compression is reversible, the answer is: no. Lossy compression means that the image size is reduced while some data from the original image file is eliminated. What Is Lossy Image Compression and How It Works Read the article, and you’ll learn everything you should know about the two image compression types. It all boils down to which lossy or lossless algorithm is used to optimize each image. Don’t worry: we’ve got you covered.īefore we get started, you should know that there is no single best format or “quality setting” for images. There are pros and cons to both, and you, as a website owner, should evaluate both before making a decision. You can choose two types of compression when optimizing your images: lossy and lossless compression. Reducing the size of your photos for the web can help you gain precious milliseconds of load time. Depending on how much you compress, the results can be quite noticeable.If you are looking into optimizing your website’s performance, you will come across some performance techniques such as image compression. You can also do lossy PNG compression by reducing the color depth and other factors. This compression doesn’t just save you a lot of space you also get a more convenient way of storing them in archives, like compressed folders. The best option to compress your PNG files without affecting image quality is using a program such as WinZip. This delay is usually not a problem unless you have a slow computer or compress thousands of PNG files simultaneously. This compression does not impact image quality like with JPEG it merely optimizes how you store the file on your hard drive.īut exporting your PNG file using more compression takes a longer time. In image editing software, you can often set the amount of lossless compression when saving in PNG. If your website contains many PNG images and you were to reduce their file sizes by only 20%, it adds up, resulting in faster loading times after compression. Coincidentally, file size also impacts loading times on websites. By reducing file size with compression, you can store more images and other files. PNG files are high quality and often take up a lot of space on your hard drive. There are two main reasons as to why someone would want to compress PNG images. It’s better than nothing, but if you’re looking to heavily compress your PNG images, lossy compression or using WinZip are better ways to go. In size, you’re typically looking at a 0-10% reduction. With lossless compression when exporting your image, the file size reduction typically isn’t that great. Sometimes the difference is noticeable, other times not. But this comes at a loss of image quality, which is why this is called lossy compression. Changing your color depth from 24-bit (16 million colors) to 8-bit (256 colors) can reduce the file size by 50% or more.
