Most online converters upload your files to a server, which is risky for contracts, IDs, bank statements and personal photos. ConvertBrightly works differently: every tool is a static web page, and the processing happens in your browser with well-known open-source libraries such as pdf-lib, Mozilla pdf.js, SheetJS and fflate. Your files never leave your device, so there is nothing to leak, store or delete.
It is also fast. With no upload or download wait, a 20 MB PDF merges in about a second, and HEIC photos convert as quickly as your phone can decode them. Everything is free, with no account, no daily limits and no watermarks.
