Every modern device can fill in a PDF using free tools. On a Windows or Mac computer, the free Adobe Acrobat Reader includes a feature called Fill & Sign that lets you type directly onto any PDF, add checkboxes, and insert signatures. Mac users can also use the built-in Preview app. On mobile, free apps like Adobe Acrobat Reader, Foxit PDF, or your device’s built-in PDF viewer can do the same. The Resources section of MyVolt includes a step-by-step guide with screenshots, so your team can get started without any learning curve.
