To transfer data or files from a local computer or device to a central, remote server or cloud system.

Upload is directional: it always moves data 'up' from the smaller, local device (like a phone or laptop) to the larger, central network (like the internet or a cloud server).

The story behind the word. The word upload is a modern compound. 'Up' signifies moving toward a larger, central system, while 'load' comes from the Old English word meaning to carry or transport cargo. It was coined in the 1970s alongside 'download' as computer networks began to connect individual terminals to central mainframe computers.

Word relationships

  • transmit: Transmit is a broad scientific term for sending signals or data, while upload specifically refers to moving a file from a local client to a remote server.
  • submit: Submit refers to the administrative act of presenting something for review, which often involves uploading a file, but is not a technical term for data transfer.
  • download: To transfer data from a remote server or system down to a local device.

Commonly confused with

  • synchronize: Uploading is a one-time transfer of a file from local to remote, while synchronizing is an ongoing process that keeps files identical in both locations.

Word family

  • uploader (noun): A person or program that uploads data.

Example sentences

  • "Make sure to upload your completed essay to the student portal before the midnight deadline." Submitting schoolwork online.
  • "It takes longer to upload high-definition videos because of our slow internet connection." Sharing media on social networks.

Memory hook

Imagine throwing a package 'up' onto a high shelf. You are uploading the file to the high cloud server. Upload sends files up to the cloud.

When not to use

Do not use upload when you are copying files between two folders on the same computer, or when transferring files from the internet down to your device (use download instead).

Fun facts

  • For most home internet connections, upload speeds are significantly slower than download speeds. This is because internet service providers assume average users spend more time consuming content (downloading) than creating and sharing it (uploading).
