# WorksOffline.in > WorksOffline.in is a free hub of privacy-first browser tools (PDF, photos, video, subtitles, notes, developer utilities) that process files locally on your device with WebAssembly and on-device AI — no uploads. ## What it is A portfolio of independent single-purpose web apps. Each tool runs client-side in the browser; files are not sent to a server for processing. Most work offline after the first load. ## Privacy Processing happens in your browser. The hub site uses Google Analytics for page-view statistics only; your files are never part of that. ## Limits Speed and maximum file size depend on your device's memory and browser. Some AI tools (captions, notes chat) need WebGPU and download a model on first use. Some tools rely on newer browser APIs (EyeDropper, Document Picture-in-Picture) that are Chromium-only at the time of writing. ## Pages - [WorksOffline.in home](https://worksoffline.in/): Directory of all tools. - [Offline alternatives](https://worksoffline.in/alternatives/): Honest comparisons of our offline tools with popular online services. ## Tools - [PresetPhoto](https://presetphoto.worksoffline.in): Exam Photo Processor — Process photos and signatures for government exam applications.
