Hey developers,

Tired of uploading sensitive files or personal documents to unknown cloud servers just to resize a photo or generate an invoice?

I built ToolNovus — an all-in-one browser utility suite with 56+ fast, client-side tools that run 100% inside your browser memory using Vanilla JS, WebAssembly, and Canvas API:

Developer Utilities: JSON to CSV, Bcrypt Hasher, JWT Decoder, URL Encoder.
Freelancers & Remote Workers: Freelance Fee Calculator, Invoice Generator, Contract Maker.
Daily Productivity: Typing Speed Test, WhatsApp Link Generator, Exact KB Image Compressor.

Zero tracking, zero file storage on servers, and completely free.
Check it out here: https://toolnovus.com — would love your honest feedback and feature requests!
