Choose between clean text reconstruction and the amount of source formatting the browser can interpret
DOCX is a package of document structure, styles, relationships, and media. The browser parser can extract useful HTML or raw text, but macros, tracked changes, comments, floating objects, uncommon fonts, fields, footnotes, and complex section layout may not reproduce. TXT has even less structure and relies on the selected typography and line breaks.
Pagination
Page size, margins, font, spacing, and alignment determine the new page breaks
A4 and Letter dimensions do not contain the same line length, and a small font can fit more content at the cost of readability. Preview headings, tables, lists, long URLs, and page transitions. A clean reflow may be preferable for notes and drafts, while an official form, resume, or branded report usually needs export from Microsoft Word or LibreOffice.
Verification
Compare content as well as appearance before treating the PDF as final
Check names, dates, numbers, symbols, links, tables, images, headers, and final page count. The copied extracted text can help identify omissions, but it does not prove visual fidelity. Open the PDF in a separate viewer and retain the DOCX or TXT source for correction and future accessible formats.
