What does upload mean?
Upload is the standard term for transferring digital content from one device or system to another, usually by sending a file, image, video, or set of data to a remote server or online service. The verb is widely used in computing, social media, publishing, education, and business, while the noun can refer either to the act of transferring content or to the uploaded item itself. For example, a person may upload a document to a shared drive, and another may upload a video to a public platform. The word is precise rather than merely decorative: it identifies the direction of the transfer and distinguishes it from the reverse process of obtaining content from a remote system. Although “upload” is now common in general use, it retains a clearly digital and technical character. Its meaning can vary slightly by context, but it always involves sending or publishing content from the user’s side to another system or location.
To transfer files, data, or other content from a local device or system to a remote computer, server, or online service.
"Please upload the revised document before the meeting."
The act of transferring digital content to a remote system, or the item or content that has been transferred.
"The upload remained available for several hours after the page was refreshed."
The noun is countable and can refer to a particular act of uploading or to an uploaded item, such as a video, image, or document.
Use the plural for separate acts of transferring content or for individual uploaded items.
"The platform received thousands of uploads from users around the world."
Upload is a digital compound of “up” and “load,” but “up” means into a remote system—not physically upward.

Where does upload come from?
Upload is a twentieth-century compound formed from up and load, both of which are older English words. “Up” comes from Old English upp, while “load” developed from an Old English term associated with a way, journey, or carrying. In computing, upload emerged as a technical term for transferring data into a remote system; download was later developed as its directional counterpart.
