About QuickKit
QuickKit is a growing collection of free online tools built around one uncompromising principle: your data is yours, and it should never leave your device.
Why we built QuickKit
Search for "compress an image" or "merge PDF" and you'll find dozens of websites that do the job — but almost all of them work the same worrying way: you upload your file to their server, they process it there, and you download the result. For a holiday photo that might be fine. For a signed contract, a passport scan, a medical form, or an unreleased design, it means handing a private document to a company you know nothing about, with no guarantee about how long they keep it or who can see it.
We thought that was backwards. Modern web browsers are astonishingly capable: they can resize images, build PDFs, hash data, and generate secure passwords entirely on your own computer, using standardized technologies like the Canvas API, the Web Crypto API, and WebAssembly. So we built QuickKit to do exactly that — every tool runs 100% locally in your browser. Your files and text are never uploaded, transmitted, logged, or seen by us. Many of the tools even keep working after you go offline.
What you'll find here
Our toolkit spans everyday needs and developer utilities alike: image compression and resizing, image-to-PDF and PDF merging, QR code generation, a cryptographically strong password generator, SHA hash and Base64 tools, a JSON formatter, a color converter, a word counter, unit and timestamp converters, a UUID generator, and more. Each tool is paired with a plain-English guide that explains not just how to use it, but why it works the way it does.
Our commitments
- Private by design. Your content is processed on your device and never sent to a server. This isn't a policy we promise — it's how the tools are technically built.
- Free and open access. No account, no paywall, no watermark, no trial that expires. The tools are free to use as often as you like.
- Fast and lightweight. The site is static HTML that loads instantly, works on any modern device, and doesn't track what you do inside the tools.
How we fund the site
Running and improving QuickKit takes time and hosting. We cover those costs through unobtrusive display advertising and occasional, clearly labeled recommendations for products we think fit our audience. We never sell your data — in fact, because the tools run locally, there's nothing to sell. If you'd like to support us directly, there's a donation link in the footer.
