Everything you need to know about Toolium, our 100% client-side privacy model, offline execution, and how our developer utilities work.
Toolium is a modern suite of high-performance developer, designer, and daily productivity utilities. Unlike traditional web tool platforms that upload your files, passwords, and data payloads to remote cloud servers for processing, Toolium executes 100% of calculations directly inside your browser sandbox using modern JavaScript, WebAssembly, and Web Workers. This ensures ultra-fast execution, zero latency delays, and complete data privacy.
No. We have zero backend databases or logging servers for tool inputs. When you format JSON, generate a secure password, convert an image, or merge PDF files, the data stays exclusively inside your device's memory (RAM). When you close the browser tab or reload, the data is completely wiped. We cannot see, intercept, or sell your data under any circumstances.
Computations run entirely inside your browser memory. No inputs or files are ever sent to remote servers.
