About KitLoop (kitloop.io)
Free online tools for developers, creators, and everyday tasks.
KitLoop is a collection of free, no-sign-up tools for everyday developer and office tasks: formatting JSON, merging PDFs, compressing images, generating QR codes, converting units, and more. Most tools run entirely in your browser, so your files and text never leave your device. A handful can only work online (AI writing tools, DNS/WHOIS/IP lookups, page speed tests, short links), and each of those is clearly labelled on its tool page.
Private by Default
Browser-based tools process your files and text on your own device. Tools that need a server say so up front.
Real Implementations
Built on real standards and libraries: Web Crypto, Canvas, pdf.js, pdf-lib and Tesseract OCR.
No Sign-Up Needed
Every tool works without an account. A free account raises the daily limits and unlocks short links.
Engineering & Team
KitLoop is built and maintained by an independent developer. You can reach out via contact@kitloop.io.
