Your Data Never Leaves
Your Device
Privacy-first utility tools powered by WebAssembly. Process PDFs, images, and more — everything happens locally in your browser.
Processing Locally
Your data stays here
TL;DR
WorksOffline.in is a free collection of browser tools for PDFs, photos, video, subtitles, notes and developer tasks. Files are processed locally on your device with WebAssembly and on-device AI, so nothing is uploaded. The main limit: speed and maximum file size depend on your device's memory and browser.
AI agent ready (WebMCP): browsers that support navigator.modelContext can call find_tool and list_tools on this page.
