As answered by people managing JSONLint and Kitbench.
Kitbench's answer:
If you want to merge a PDF, compress an image or make a QR code without creating an account or sending your files anywhere, Kitbench lets you do it in a few clicks for free. All the tools share the same simple layout, so once you have used one, the others feel familiar.
Kitbench's answer:
People who need a quick tool during everyday work or study: office workers handling PDFs and images, students and teachers, small business owners, and anyone who wants a simple tool that works in the browser without installing software.
Kitbench's answer:
Static web pages with JavaScript. PDF and image processing run in the browser using standard web APIs and open-source libraries, so files do not need to be uploaded.
Kitbench's answer:
Kitbench puts 50+ everyday tools in one place, and most of them run entirely in your browser. Your PDFs and photos are processed on your own device and are not uploaded to a server. There is no account or sign-up, and the site works in 12 languages.
Kitbench's answer:
Kitbench started as a small set of browser extensions for everyday work on the computer. We kept building the tools we needed ourselves, and turned them into web tools so anyone can use them in a browser without installing anything. It is made by a small company in Japan.
