What is MinKit?
MinKit is a free collection of mini productivity tools you use directly in your web browser. We built it for people who need to resize or compress an image, merge or split a PDF, format or validate JSON, compare text, pick colors, or create QR codes and barcodes without installing heavyweight desktop apps or handing files to unfamiliar cloud services. When you open a tool, the heavy lifting runs locally on your device with JavaScript in the page, which means your documents and images are not sent to our servers for that processing. Each tool page explains what the feature does, what inputs we support, and realistic expectations around limits such as file size, browser memory, and performance on older hardware. Some visitors may see advertising or measurement only after they interact with our cookie notice where applicable; we load optional analytics the same way. The core file and text utilities are designed to keep your content in the browser unless we clearly document an exception. There are no forced accounts, subscriptions, or paywalls to use the basics. If something breaks in your browser, updating to a current version of Chrome, Firefox, Safari, or Edge usually resolves compatibility issues. Our Privacy Policy describes how language storage, optional analytics, and advertising fit together so you can decide what you are comfortable with before you continue.
