How to convert PDF to Word

To convert a PDF to Word, open Microsoft Word, click File > Open, and select your PDF file. Word will automatically convert the text and layout into an editable DOCX document. Alternatively, use a trusted client-side tool or Adobe Acrobat to export your PDF into Word format while preserving formatting.

A PDF (Portable Document Format) is a versatile file format created by Adobe that preserves text formatting, vector graphics, and images exactly as designed. It ensures that documents display identically across all operating systems, web browsers, and printers without requiring original fonts or applications.
