Blurry Images on my Website

Text on images always look blurry when you view it at any other size than 100%. You can try saving them as an svg and using that, then you have to install a plugin that let’s you upload svg’s into your site.
Or can make it show text on the image but the images you have would take a lot of work. In a program like PPT you can zoom in and out because it is vector type stuff, but or .png, .jpg, .webp you blur the text by zooming. Most people have their monitor set to 100% I assume.
And no, I don’t think larger images will help since the zoom does not enlarge the image in that way.
