How to Optimize Your Images for WordPress Using Free Tools

Introduction to Image File Format:



You need to consider 2 things when saving images: compression and image file format . By choosing the right combination, you can decrease your image size by 5x.

The only two image formats that matter the most are JPEG and PNG. To keep things simple, use JPEGs for photos or images with lots of color, and use PNGs for simpler images or when you need transparent images. For those who don’t know the difference, PNG image format is uncompressed which means it is a higher quality image but the file size is much larger. Meanwhile, JPEG is a compressed file format which reduces image quality slightly in order to provide a significantly smaller file size.

Compression can makes a huge difference when it comes to image optimization. Compression can be done by using tools which are designed to reduce original file size to a smaller file size.

In this article, we recommend top 3 free tools you can use to optimize images for your WordPress blog.
