LocalFlux

LocalFlux is a Windows 11 desktop app for local file conversion and compression. Convert supported images, video, audio and documents without uploading source files. Batch-convert HEIC photos to JPG, create WebP images, reduce video file sizes and turn compatible Office documents into PDFs. Drag files into the app or start from File Explorer quick actions. Each result is saved as a new file, keeping originals unchanged. Share safely creates supported image copies with location, device, author and date metadata removed; it does not conceal people or text visible in an image. Supported processing works offline after Microsoft Store setup, with no LocalFlux account or subscription required. Available for Windows 11 on x64 and ARM64, with a free trial followed by a one-time purchase. Pricing varies by region.
