2 Different Types of Image Compression

By considering the image quality and types. There are two basic categories of image compression. 

1. Your Image will not lose any image quality after compression (Lossless)

Lossless compression is the process of storing the same quality of an image before compression with a gradual size reduction. This way images don’t appear blurry or contain any sort of reduction. 

Here are some of the image formats we are talking about, 

  • PNG (Portable Network Graphics): PNG images are generally reversible. Once you compress this format, it will get back to the regular size when you open the file.
  • RAW(Portable Network Graphics): Raw images are derived from DSLR (Digital Single-lens Reflex). These files are huge, and might lose quality after compression. 
  • BMP (Bitmap): BMP is exclusively found in Microsoft, though it’s not that popular as a web image format. 

PNGs are the best image format for any website, because they don’t lose their image quality even after compression.

After you compress an image, you will lose its quality dramatically with a huge size reduction eliminating some parts of your file. Also, it’s an irreversible process once you are done with it. 

This compression type is not so popular and not recommended by professionals for uploading images on your website. Lossy image formats are, 

  • JPG (Joint Photographic Group): JPG is commonly known as JPEG. Under lossy compression, this format eliminates some parts of the image. Though a small amount of compression won’t be noticeable, the greater size will appear great.
  • GIF (Graphics Interchange Format): This format reduces the file size by reducing the color. Usually, a file with 256 colors looks appealing. You can minimize the size by reducing the pixel count.
