Fine Uploader je komponenta za nalaganje datotek, implementirana s tehnologijo Ajax, ki podpira nalaganje datotek z vlečenjem in spustom. Enostavno ga je uporabljati, samo dodaj ustrezni CSS+Javascrip{filter}t v stran, ostalo pa je logika obdelave na strežniški strani. V paketu za prenos, ki ga ponuja, je že več jezikovnih implementacij: ASP.NET, ColdFusion, Java, Node.js, Perl, PHP, Python.
