In this post, We will learn uses of WebP image in Android. In earlier, You are heard many image processing library on android eg. Glide and Picasso. We mostly use  SVG and PNGs image file format for android app development.

Basically, The major problem is size of FILE and while we applied compression on image file the resulting quality is very poor. Because PNG and JPG have very different image compression processes and each reproduces different result.  

Image loading has consisted of more network traffic in android apps. the smaller image provides better network experiences. WebP provide guidance on making image file smaller and more network network-friendly.

WebP is lossy compression for image like JPEG as well as transparency like PNGs.  that provides superior image quality with 26% smaller size compared to PNGs and 25-34% smaller than JPEG.  The best things is it reduces the image size in a good amount without reducing the image quality.

With help of AndroidStudio, you can convert existing PNG, JPG, GIF or static BMP images to WebP format easily. In furthermore we will explain “how to create a WEBP image using AndroidStudio?”.
