To upload is to send a file from your device up onto the internet. Upload a photo, upload speed, still uploading.
Home connections are usually much faster at downloading than uploading, which is why sending a large video takes so long and why video calls suffer first when a line is busy. Uploading and posting are not the same: a file can be uploaded and never published. Note download, its exact opposite.

Cognate with Middle Low German leide (“entourage, escort”), German Leite (“line, course, load”), Swedish led (“way, trail, line”), Icelandic leið (“way, course, route”).

Most likely, the semantic extension of the Middle English substantive arose by conflation with the (etymologically unrelated) verb lade; however, Middle English lode occurs only as a substantive; the transitive verb load (“to charge with a load”) is recorded only in the 16th century (frequently in Shakespeare),
