SpinShare is a file conversion application for Windows PCs. Its primary function is to convert files between various formats, including images, video, audio, PDFs, documents, archives, and subtitles. The application processes all conversions locally on the user's machine, meaning files are not uploaded to external servers. This approach ensures privacy and allows the tool to function fully offline without requiring an internet connection or user sign-up. The application offers over 300 conversion options and 35 built-in tools. Users can perform actions such as cropping, compressing, trimming, splitting, merging, redacting, and editing metadata, as well as file actions like copying, moving, or opening the file location. The workflow is centered around a drag-and-drop interface. A user drags a file onto the application window and can tap the Shift key to select a format, the Ctrl key to access tools, or the Alt key for file actions. Keyboard navigation is also supported for users who prefer it. Common use cases include converting iPhone photos for web upload, resizing screenshots, converting PDFs for editing in word processors, and changing video formats for sharing. The software is available through a lifetime license model that covers up to three PCs. Pricing tiers are offered during its initial availability period.
