Which file format is most suitable for storing forms captured electronically?

the question asks for the most suitable file format for storing forms captured electronically.

The PDF (Portable Document Format), developed by Adobe, is the industry standard for storing, sharing, and archiving electronic documents and forms. It preserves the exact formatting, fonts, layouts, and graphics of the original document regardless of the operating system, hardware, or software being used to view it. Furthermore, PDFs support interactive form fields (fillable forms), digital signatures, data encryption, and structural metadata, making them highly secure and efficient for processing legal, official, and business documents.
