How Handful Tools works
What happens to your files, tool by tool- Runs on your device
- Most tools process files inside your browser, so documents are never uploaded. Where a tool needs more, its page says so.
- One page, one job
- No account, no watermark, no fake download buttons. Each tool loads only the code it needs.
- Checked before it ships
- Every tool is tested in a real browser on desktop and mobile. Tools that can't be made reliable are not published.
