About SwiftFiles
File tools that do not need your files
SwiftFiles brings 65 browser-based tools together in one place. Built by K-Space, it handles images, PDFs, audio, text, and archives, while Smart Pipeline turns compatible tools into reusable multi-step jobs. Everything is free, there is no account to create, and the files you select are processed on your device.
Privacy starts with the architecture
A typical online file tool sends your document, image, or recording to a remote server before the work begins. SwiftFiles is built around a different boundary. Supported operations run inside the browser with JavaScript, Web APIs, WebAssembly, and focused processing libraries. File contents, filenames, and passwords are not sent to SwiftFiles for processing.
Loading the website still requires network requests for the application, updates, analytics, advertising, and some browser resources. Analytics records coarse product events, such as a tool opening or finishing a job. It does not include file contents, filenames, passwords, or text read from a file.
What stays on your device
The processing work
Your browser uses the device's CPU and memory. That keeps file data local, but it also means a large PDF, long recording, or complex archive may take longer or reach a browser limit on an older device.
Files and saved workflows
SwiftFiles does not require an account or keep copies of processed files. Smart Pipeline configurations saved in the browser contain operation settings, not the files they were used with.
A project you can inspect
The public repository shows how the website is assembled and gives developers a direct way to review its implementation. The Firefox add-on brings a focused set of local tools into the browser toolbar.
Built for practical file work
The application uses Next.js 16, React 19, TypeScript, browser APIs, and libraries chosen for specific jobs, including pdf-lib, PDF.js, FFmpeg.wasm, JSZip, libarchive.js, and the Web Audio API. Browser support differs by format, so tool pages call out the limits that matter to each operation.
Check the privacy claim yourself
Open the Network panel in your browser's developer tools, then process a file. You will see requests for application resources and possibly analytics or advertising. You should not see a processing request carrying the file you selected. The project source and Firefox add-on are available for further inspection.
