Why hyperlinks break in Word-to-PDF conversion and how to fix each cause.

Recover unsaved Word documents: AutoRecover file locations, temporary files, and the Recover Unsaved Documents path.

Stop Word compressing images: disable image compression, re-insert originals, and keep quality through PDF export.

Repair chaotic Word formatting: clear direct formatting, reapply heading styles, and paste without bringing foreign styles.

Word section breaks for page numbering: no numbers on the cover, restart at 1 in the body, fix TOC page numbers.

Four paths to edit a PDF chosen by scenario.

Add text to a PDF with DocsAll: overlay-based stamping, how Chinese text is embedded, coordinate basics, and when this is the wrong tool.
