File Size Calculator FAQ
Does File Size Calculator change my original input?
No. ToolFlow works on a temporary upload or submitted value and returns a separate result. Your local original is not overwritten.
Do I need to install software to use File Size Calculator?
No browser extension or desktop application is required. Some file tools depend on server modules such as FFmpeg, GD, Poppler or LibreOffice being enabled by the site operator.
