About Toolkit
Toolkit is a free collection of fast, no-nonsense tools that run entirely in your web browser — your files never leave your device.
What Toolkit is
Toolkit brings together the small utilities you reach for all the time — image converters and resizers, a password generator, JSON/CSV/YAML formatters, a QR-code maker, calculators and dozens more — in one clean, ad-light place. Every tool is free, needs no account, and works instantly.
Privacy by design
The idea behind Toolkit is simple: your data stays yours. With very few exceptions, every tool does all of its work locally, inside your browser. When you convert a photo, hash a file or encrypt a note, the data is read and processed on your own device and is never uploaded to a server — that isn't just a promise, it's how the tools are physically built. It also means there's no per-use cost, no queue and no size limit beyond your own device.
The two tools that do talk to a server are upfront about it: the image converter can optionally fetch an image from a URL you paste, and the one-time link stores only end-to-end-encrypted ciphertext — the decryption key lives in the link itself and never reaches us. Every tool page spells out exactly how it works under “How it's built & why it's safe.”
How it's built
Toolkit is a plain static website — hand-written HTML, CSS and vanilla JavaScript, with no heavyweight framework and no build magic. The tools lean on trusted open-source libraries and built-in browser APIs (the Web Crypto API for randomness and encryption, the Canvas API for images, and so on). Because it's all static and client-side, the site is fast, keeps working after it has loaded, and is completely open for you to inspect with View Source.
How it stays free
Toolkit is supported by unobtrusive ads, kept out of the way so the tools stay usable. Because everything runs locally, there's nothing to harvest — we don't trade in your files or personal data. See the Privacy Policy for details on analytics and advertising, and the Terms of Use for the fine print.
Who it's for
Anyone who needs to get something done quickly without installing software or handing a file to a stranger's server — developers, designers, students, photographers and everyday people alike.
