If that's not possible, then try to record it safely, in a way that doesn't link it to your use of SecureDrop. Never share it with anyone, including journalists. Keep it secret, keep it safe . Uploading files via Tor Browser can be slow. If you are planning to upload large files, you should be prepared to wait, and for really large submissions (larger than 500MB) you may need to message journalists via SecureDrop first to arrange other safe transfer methods.
