NK Tools
Fast, free & private online tools that run 100% in browser
NK Tools is a suite of 32 free, fast, and privacy-first utilities for everyday tasks. Everything runs 100% locally in your browser memory with zero file uploads: • Calculators: EMI, Loan, Percentage, BMI & Age • Text: Word counter, case converter, line cleaner • Images: Image compressor, cropper & WebP converter • Developer: JSON formatter, Base64 & UUID generator • PDF: Merge, split & convert documents securely Free forever, no signup required.
Hey Product Hunt! 👋
I built NK Tools because I was tired of online tool websites that require signups, show aggressive popups, or force you to upload private contracts, personal financial numbers, and photos to unknown cloud servers.
With NK Tools, privacy is built right into the architecture:
🔒 100% Client-Side: Every file, calculation, and string manipulation executes directly inside your browser memory.
⚡ Instant: Zero server queues or upload delays—built on modern Web APIs, Canvas, and WebAssembly.
🚫 Zero Barriers: Completely free with no accounts or subscriptions needed.
We currently have 32 utilities across Calculators, Text Tools, Image Optimization, Developer Utilities, and PDF manipulation.
I'd love your feedback! Which tools do you use most, and what should we build next?
