Security at ToolBox

Security isn't an afterthought at ToolBox — it's the foundation. Our architecture is designed so that we physically cannot access your data.

Client-Side Processing

Every tool runs entirely in your browser. When you upload a file, it never leaves your device. We use WebAssembly (WASM) to run powerful libraries like PDF-lib, Tesseract OCR, and FFmpeg directly in your browser at near-native speed.

No Server Uploads

Traditional online tools upload your files to their servers for processing. We don't have upload endpoints because we don't need them. Your files are processed using the FileReader API and Blob URLs locally.

HTTPS Only

ToolBox is served exclusively over HTTPS. This ensures that the code you receive is authentic and cannot be tampered with in transit.

Cookies & Consent

We do not use tracking cookies without your consent. Essential and functional cookies may be used to keep the site working and remember your preferences (such as recently used tools in localStorage, which stays on your device).

With your consent, we use Google Analytics 4 to understand how visitors interact with the site and Google AdSense to serve ads. You can manage or withdraw consent at any time through the cookie banner or on our Cookie Policy page.

Open Source Components

We build on trusted open-source libraries: PDF-lib, PDF.js, Tesseract.js, jsPDF, html2canvas, Chart.js, and more. These libraries are widely audited and trusted by millions of developers.
