Free WordPress image compression plug-in Imagify

Imagify It's a WordPress image compression plug-in , providing lossy compression function. and EWWW Image Optimizer The free version can only perform lossless image compression, and the compression ratio is not large. On the other hand, the lossy compression of the free version of Imagify achieves a very high compression ratio with little loss of image quality, and the difference between before and after is almost invisible to the naked eye.

1. Imagify Installation Enable

Optimization level

The plug-in provides three different compression levels: normal, aggressive, and ultra strong.

Normal is "lossless" image optimization. This means that there is no loss of image quality after compression.

Aggressive and Ultra are lossy compression with reduced image quality. The former is not obvious by naked eye, while the latter can find differences.

Lao Wei suggested taking Aggressive as the best balance level to reduce the image size without affecting the quality.

You can also test three more compression methods to see how they affect your website images.

Back up original images

When enabled, the optimized version and WebP version of the original format image (JPG/PNG) are obtained. Provides support for users who use browsers that do not support WebP. If the browser supports the webp format, the WebP image will be displayed on the page. If the browser does not support the webp format, the original format version will be used.
