FastDrop is a file-hosting and sharing service designed for people who want to send files quickly without creating an account. Since 2019, it has focused on a simple process: upload files, receive private links, and share them with others for download. Users can select or drag and drop one or multiple files, then copy individual links or copy all links together, with the option to include file names.

FastDrop describes its transfers as streaming to cloud storage to help large uploads proceed without stalling. Each file receives a direct URL, and recipients can open the link and download in their browser on a desktop, tablet, or phone. Files are not shown in a public library, and the service says only people with a link can access them; there is no public search or account requirement for recipients. FastDrop also provides information about its features, security, terms, privacy, and contact options for abuse or copyright reports.
