About this tool
- Where it runs
- Right in your browser, on your own device. The file goes nowhere — unless it turns out too large for the browser, in which case we say so and fall back to the server.
- What it accepts
- Files of any type: the contents do not matter here.
- Limits
- Up to 20 files at a time, each up to 20 MB, 60 MB in total.
