product-images
I'm looking to upload my products into my Magento 2 store. However, before hand I want to make sure the images are correct.
I've resized my images to 600px in width (height depends on ratio), and compressed my images to around 20/30 KB each.
Are these images good to be uploaded onto my store?
I plan to use the same image for the variations of reasons per product? Shall I do this or resize images for each varietion (thumbnail, base, product page etc)?
Thanks
You can define the base product image dimensions in config -> catalog -> product image.
I expect it would be possible to write a custom module to further perform image resizing but it would be simpler to either create your images in the format you want or use a free image editing package (such as IrfanView) to bulk modify the images you want to use before you upload them.
You can assign images to product by import product csv.
Check below sample csv file for import sku with image, assing images to product.
Let me know if you have any query from above.
I hope it will help for you.

Instead of optimizing before uploading image consider the alternative to optimize each image request to the server.
It has several advantages:
mod_pagespeed is an extension to apache or nginx that will do this. It acts a an intermediate and will serve different images depending on configuration, size, user media etc.
By using mod_pagespeed, there is no need to be an expert in image compression, someone else has done the thinking. Just set the filters (/ settings) and get a tremendously more optimized web shop.

mod_pagespeed can be used for other optimization besides image optimization. The optimization is turned on through config files through something referred to as filters. Some filters may break your web page, so do proper testing. Read about how you can configure pagespeed filters.
