Frequently asked questions
- Is there a file size limit?
- There's no server-imposed limit since everything runs on your device. The practical limit depends on your browser's available memory — most files up to a few hundred MB work fine.
- Is this actually secure if it runs in my browser?
- Yes. Your browser's sandboxed environment means the data can't leak to other tabs or processes. Since nothing is sent over the network, there's no server breach risk. You can verify by checking the Network tab in DevTools — zero requests with your data.
