About UtilKit
UtilKit is a free, fast, and privacy-focused collection of online utilities for developers, designers, and everyday users. Every tool runs entirely in your browser — your data never leaves your device.
Our Mission
We believe everyday tools should be fast, free, and private. Too many online utilities upload your data to remote servers, inject trackers, or hide useful features behind paywalls. UtilKit takes a different approach: every calculation, conversion, and transformation happens client-side using modern browser APIs and well-established open-source libraries.
How It Works
UtilKit is a static web application built with Next.js and React. There is no backend server processing your data. When you paste text, upload an image, or generate a password, everything is computed locally in your browser. Nothing is stored, logged, or transmitted.
What We Offer
Our growing toolkit includes utilities for:
- Text: Case conversion, sorting, diffing, cleaning, word counting, and more.
- Developer Tools: JSON formatting, Base64 encoding, JWT decoding, regex testing, hashing, and data format conversion.
- Colors: Color conversion, palette generation, gradient building, and contrast checking.
- Images: Resizing, compressing, format conversion, EXIF viewing, and color picking.
- Generators: Passwords, UUIDs, QR codes, barcodes, lorem ipsum, and fake data.
- Calculators: Unit conversion, percentage calculations, date differences, and number base conversion.
Open and Free
All tools on UtilKit are completely free to use with no account required. The site is supported by non-intrusive advertising through Google AdSense. We respect your choice to use ad blockers.
