Privacy and security
Your file is read directly from your device and processed in your browser. It is never uploaded to a server, so there is no copy for us to keep, share or lose. Closing the tab discards everything. If you want to check this yourself: open your browser’s developer tools, switch to the Network tab, and use the tool — you will see no request carrying your file or input leave the page.
