We just added paid plans to our top three online tools websites – PNG Tools, JPG Tools, and GIF Tools. These three websites are collectively used by over a million users every month. As soon as we launched the paid plans, customers started pouring in and we have already signed up our first 150 online tools customers! Next, we're adding paid plans to all other online tools websites that we built and eventually joining them into a single ultimate get things done website called OnlineTools.com (we already bought this premium domain!)
From technical standpoint, we used programming, Google SEO, and a $5 Linode instance to launch the paid plans. Checkmate, front-end developers and devops engineers.
You can still use the free tools version but if you really like them, then you can get a subscription to support my team's work. See you next time!
