Hi there,
I very much dislike the idea of having the same image 5 times in my files, so I wrote a plugin that removes the smaller image sizes and resizes big images so that the client’s images don’t end up taking up a few MBs.
Are there any risks to doing so? Should I leave a thumbnail version for the media library or anything else? Do you suppose the site will be slower without the scrset of size variations?
Thanks!
PS: Are there any webp conversion plugins that don’t require the image being sent to third party servers?

I wouldn’t mess around with the image variations.
Themes include specific lines of code that tell WordPress what kind of image variations (different resolutions) it has to make. Those variations are used in different places throughout the theme. If you delete those variations, the images can’t be loaded and you can end up with broken images on your site.
In fact, your site will probably be slower when you only use the original size image instead of using the dynamically created thumbnails.
It really doesn’t take up that much space. Disk space is cheap as well, so I wouldn’t worry about it. You can worry about it if it really becomes an issue, but I wouldnt “future-proof” your site by removing core functionalities that your theme relies on.
