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?
