Frequently Asked Questions
Find answers to common questions about file privacy, client-side processing, and tool usage.
Yes! All utility tools on Free Browser Tools are completely free to use with no usage limits, no credit point deductions, and no hidden subscriptions. We display privacy-compliant advertisements (via Google Ad Manager) to support operational costs.
No. Your files, images, documents, audio, video, and text are processed 100% locally inside your browser using WebAssembly (WASM) and JavaScript. Zero bytes of your files or personal data are ever transmitted or saved to external servers.
No account registration, sign-up, or login is required. You can start using any tool immediately without providing your email or credentials.
Our tools leverage modern client-side browser engines including WebAssembly (WASM), Tesseract.js for OCR, OpenCV.js for Computer Vision, FFmpeg for audio/video processing, Transformers.js for AI models, and Web Worker threads for high performance.
Once the tool page and required WASM binaries/models are cached by your browser, many of our utility features can execute completely offline without an active internet connection.
Because processing occurs on your local device, file size limits depend strictly on your device's memory (RAM) and browser CPU capabilities.
