Trying to upload RAW Photos to iCloud, but only JPEGs are allowed

I'm trying to upload a ton of pictures from Spain and other places from my Windows computer to Icloud so I can view and share them on my phone. But the app or website or whatever says that "oNlY fIlEs In JpEg FoRmAt CaN bE uPlOaDeD" so basically thats almost 1000 photos I can't use on my phone all because I wanted the best image quality so I chouse to take them in RAW format. There seems to be some really, work arounds like "CoNvErT eVeRy PhOtO tO jPeG" or "sAvE tHeM tO ThE fIlEs ApP AnD tHeN aS aN iMaGe". But of course on the other community post i looked at didn't help at all and offer any solutions basically it said "youre screwed if its not a JPEG lol we're just not going to address any questions there" but the person who uploaded it somehow thought it was a good enough answer to close the discussion and not let any one else follow up or follow up themselves. Anyways, looking for solutions.
