What it does
SendBig offers guest file and folder uploads up to 4 GB, with a share link shown on its page and a stated three-day lifetime. Its upload path uses LimeWire infrastructure.
Select files or a folder, or drag them onto SendBig's page. The guest offer is up to 4 GB with a three-day link. Its current uploader displays a sharing link and copy control after completion; a fallback can redirect to LimeWire instead.
SendBig uses LimeWire's file-sharing library and API, so this is a branded interface within that product family. Larger transfer plans and account management belong to the linked LimeWire offer. The older FAQ also describes email delivery, passwords and Snap mode, but their availability in the current guest interface was not established. This review covers the file-to-link route without assuming those extra controls.
