what is better?

Hi @levanii,

Thank you for contacting us.

This is a great question when it comes to best practice for media being uploaded to your site. The site requests assets so they render on site. When it requests an image, if the image size is very large, it will take more time to render it versus an image that has less size. Usually higher resolution images are heavier than lower ones, and with Smush, you can help reduce this by compressing them. It’s always a good practice to not upload images to your site that are in mbs as, even compressed, they may still be large.

Let us know if you have any additional questions.

Best,

So it will be great if I reduce image size from like 1 MB to 300-400 KBs but keep resolution for example 1920 X 1080 . and then upload and use smush. is it good practice to keep high resolution (1920×1080) and only reduce file size to 300-400 kbs. In this scenario main role has file size, not resolution, am I right?

is it the best practice? See image Here

one more question JPEG or PNG, which file format is better to use, Thanks

Hi @levanii

By default on Smush free version, we will only compress your thumbnails, only on the Pro version, it will be able to Smush and original size and use the Super Smush for extra optimization.

Those thumbnails are the version of the image that WordPress create to your original image size, you can find more on: https://wpmudev.com/blog/wordpress-image-sizes/

On how much the plugin is going to compress the image depends on what needs to be optimized, but for some images around 1920px removing the metadata, it can decrease to around 200-300kb yes but really depends on how much we need to compress it.

When a user is using Smush Free which won’t include the original image it is a good idea to run save the image for the Web and using sRGB you can use software like GIMP which is free.

Guide on how we should save the image: https://www.wpbeginner.com/wp-tutorials/how-to-fix-image-color-and-saturation-loss-in-wordpress/

About 1920 X 1080, it also depends, not on all page locations we need this size, for example why using a 1920 px if the container is 500px only, for those cases you can use the thumbnail versions that are lighter too.

Let us know if you have any additional questions.
