Image Compression: The Complete Guide
As far as digital files are concerned, compression refers to the process of encoding information in such a way that it contains fewer bits than the original file. In simpler terms, it refers to changing a large file into a smaller one.
Types of Image Compression
Lossless Compression
Lossless compression is when a compression tool deletes empty, redundant, or duplicate bits of a file. This creates a smaller file that is equal in quality to the original.
Lossy Compression
Lossy compression is when the compressor deletes excessive or unnecessary bits of a file. This will result in a smaller file, albeit one with lower quality.
In terms of settings, the extent of compression that can be applied depends on how much loss of quality the viewer is willing to accept.
Why Would Anyone Want to Compress Images?
Depending on the source of an image, the file can be relatively large. A JPG image file from a professional DSLR camera, for instance, might be several dozen megabytes. Depending on your needs, this could be too large. In situations that require easier storage and better uploading speed, compressing this image would be highly useful.
In the same way, photographs may be stored on your phone's memory. These photographs may be consuming a large amount of storage space and may be restricting you from capturing more images.
Benefits of Image Compression for Websites
Increase the Speed of Your Site
Your website is so much slower than it could be - Images make up nearly half of the loading speeds! When they are optimized, a precious few seconds are gained.
Enhanced SEO
Improved loading speeds and overall website efficiency translates to being seen more often on Google, which means more visitors. While the visitors are on your site, you have the opportunity to keep them there.
