Most everyday digital tasks — converting a PDF to Word, compressing a photo so it fits an upload limit, generating a QR code for a poster, formatting a messy block of JSON, or working out a percentage — are simple in theory but scattered across dozens of different websites in practice. Each one has its own layout, its own sign-up wall, and its own pile of pop-ups. UtilKit exists to gather the tools you reach for most into a single, consistent place that loads fast and gets out of your way.
There are currently 60 tools spread across PDF, image, developer, generator, calculator, and text categories. You never need an account to use them, and there are no watermarks, trial timers, or file-size paywalls on the core tools. Browse by category or search by name — every tool is one click away and opens instantly.
Privacy is built in rather than bolted on. Wherever it is technically possible, tools run entirely inside your browser: when you merge PDFs or resize an image, the file is processed on your own device and never uploaded to a server. Every tool runs this way, so your files stay on your device. You can read more about how we handle data in our Privacy Policy.
UtilKit is designed for anyone who works with files and text online — students, professionals, developers, and creators. New tools are added regularly, and each one comes with a short guide and FAQ.
