Video Frame Extractor is a complete, production-ready web application that extracts high-quality JPEG frames from any video file. What makes it unique is its HYBRID architecture: on capable desktop browsers, the entire extraction happens LOCALLY using WebAssembly (ffmpeg.wasm) — the video never leaves the user's device. On mobile or weaker devices, it automatically falls back to server-side processing using native FFmpeg. The user always gets a result. Built with FastAPI (Python) and Docker, it's easy to deploy on any Linux server. Comes with a clean, modern dark-themed UI and a comprehensive English README covering local testing and production deployment with SSL. PERFECT FOR: developers building AI training datasets, video editors, researchers, or anyone who needs to extract frames from videos quickly and privately. The codebase is clean, well-documented, and includes full license compliance documentation (LICENSES.md). No signup system, no database required — deploy and run.
