What Happens If You Close the Tab Mid-Upload

Closing a browser tab while a file's still uploading is a common accident, and what happens next depends on how far along things were.

The Short Answer

An interrupted upload almost always fails. The file transfer needs the tab to stay open and active until it completes, closing it cuts the connection.

Why It Can't Just Resume

Most upload processes aren't built to pick back up from where they left off, once interrupted, that partial upload is typically discarded rather than resumed.

Avoiding It

For larger files, it's worth just leaving the tab open and stepping away rather than closing it out of habit. A stable connection matters too, uploads on unreliable wifi are more prone to failing partway through.

If It Happens

The fix is simply starting over, reopen the upload page and try again. There's no partial progress to preserve, so no real harm done beyond the lost time.
