![]() As a result, it likely won’t save you much storage space. ![]() The trade-off is that you won’t see a significant reduction in image file size. That’s because lossless compression only removes additional, non-essential data automatically added by the device used to take the photo. Unlike lossy compression, lossless image compression won’t reduce image quality. We’re going to discuss how to do that later on in the article. You can increase the percentage or disable the feature. JPEG image will be reduced by about 82% of its original file size. JPEG images when you upload the file to the media library. If you use WordPress, it will automatically compress. All of that said, the file size was reduced by 85%. You can only notice information loss if you zoom in on the compressed image. Here’s an example of lossy compression with ShortPixel:Īs you see, we can’t tell the difference between the original and compressed photo. They’re great for a site that needs faster loading times, as you can adjust the compression ratios while keeping the right balance. JPEG format are suitable for pictures and photographs with no transparency. JPEG format is an excellent example of lossy compression. That’s why it’s better to have a backup file before making any changes. These lossy compression algorithms can reduce the file size considerably, but that usually comes with a trade-off – the image quality will also degrade. Some of the algorithms used for lossy compression include the discrete wavelet transform, fractal compression, and transform encryption. This process is irreversible, meaning that the file information will be removed permanently. Lossy image compression is a process that removes some of the data from your image file, reducing the overall file size. Lossless compression preserves data integrity for higher-quality files and is often used for text-based files, where data integrity is critical. Lossy compression sacrifices data to reduce file size, resulting in lower-quality files. The main difference between lossy and lossless is the way data is compressed and the resulting quality of the compressed file. What’s the Difference Between Lossy and Lossless?
