About SimsimTools
What is SimsimTools?
SimsimTools is a collection of free online utilities that run directly in your web browser. Merging PDFs, compressing photos, counting characters, formatting JSON or calculating a loan payment should not require installing software or creating an account, so every tool here opens instantly and works on phones, tablets and computers alike.
Your files stay on your device
Almost every online converter uploads your documents to a remote server. SimsimTools takes a different approach: PDF, image and text processing is done with JavaScript inside your browser, so the files you select are never sent to us. This makes the tools fast, keeps working even on slow connections once the page has loaded, and means sensitive documents such as contracts or ID photos never leave your hands.
Who runs SimsimTools
SimsimTools is built and maintained by the small independent team behind SimsimPlay, a portal of instant-play browser games. We apply the same idea — open a link and start right away — to everyday productivity tasks. New tools are added regularly, many of them suggested by users.
How SimsimTools stays free
All tools are free to use with no limits on the number of files. To cover hosting and development costs, some pages may display advertising served by Google AdSense. Ads never have access to the files you process, and you can read exactly how cookies and ads work in our Privacy Policy.
