We say "could," because the final products don't always work. Ars Technica put a few applications to the test and found that a lot of them don't run on computers, because, well, they were designed for smartphones and tablets. Developers can tweak their creations if they stop running after going through ARC Welder, though. Once they're done, they can upload the files directly to the Chrome Web Store. Even if you're not a developer, you can still use ARC Welder to convert APKs on your own, but as we said, don't be surprised if some of them don't work.
