Tips for Best Results
A few practical tips: keep your source files in a single folder so you can drag them onto the workspace quickly, clear the workspace between jobs to avoid mixing inputs, and use the Copy button rather than right-clicking — some browsers block clipboard access through context menus. If you plan to repeat the same operation often, bookmark the tool page for one-click access.
