Clear explanations for everyday PDF tasks, without the unnecessary jargon.
Combining files is useful when a document has arrived in pieces: a cover letter and résumé, separate chapters of a report, or scans from several pages. Put documents in the order readers should see them, check each one for the right orientation, and then merge. Keep the original files until you have checked the final document.
Before sending a PDF, remove details that should not travel with it, including hidden metadata and comments. Use a strong password only when the recipient has a safe way to receive it. Most importantly, share documents only with people who need them and avoid public links for sensitive records.
Use Word when text needs editorial changes, Excel for data that belongs in rows and columns, and images when a page needs visual reuse. A PDF is usually the right final format because it keeps the layout consistent across devices. Always check a converted file before sharing it.
