Try perhaps https://www.bing.com/Translator
It should allow to translate your site on the fly using a frame. In the past you had also
https://translate.google.com/intl/en/about/website/ but it seems phased out to favor translating from within their browser :
https://support.google.com/chrome/answer/173424?co=GENIE.Platform%3DDesktop&hl=en (pushing their browser).
It might be a first quick step thought you may have to handle this by really translating your site (not sure what you mean by "without translating every page", you can use "resources" to fetch the phrase in the correct language but it does need some work,
you can reuse though words used on multiple pages in the same context).
