About KingTools
KingTools is a free collection of more than 100 online tools for everyday work: converting and merging PDFs, compressing and resizing images, counting words, formatting JSON, and calculating GST, EMI, SIP, age, BMI and percentages. Every tool runs directly in your web browser, so your files never leave your device.
Who we are
KingTools is built and maintained by King Brothers Private Limited, a company incorporated in India in August 2026 and based in Chandigarh. Our founder, Amit Kumar, started KingTools because small business owners, students and freelancers in India kept paying for simple tools, or uploading private documents to unknown websites, just to do a five-second job.
What makes KingTools different
- Private by design: processing happens on your device. We do not upload, store or read your files.
- No signup: every tool works instantly, with no account and no email.
- Made for India: GST, EMI, SIP, UPI QR, IFSC and GSTIN tools follow Indian rules and formats.
- Free: the site is supported by advertising, so the tools stay free for everyone.
Our guides
Alongside the tools we write plain-language guides that explain how each calculation works, so you can check the numbers yourself.
