The safest rule
Make a copy before editing. Name it clearly. Work on the copy. Keep the untouched original until the recipient confirms the final version is usable.
Documents and PDFs
Use this before sending a PDF, uploading a form, printing a packet, or archiving an important document. The goal is simple: keep an original, make the final copy readable, and avoid accidental privacy or formatting mistakes.

Use filenames that make sense after the file leaves your computer.

Questions
Compress in small steps, then reopen the file and inspect text, signatures, diagrams, and scanned pages. Use stronger compression only when the upload limit requires it.
Run OCR on the scan so the PDF gets a text layer. Check a few copied words afterward because OCR can misread faint, crooked, handwritten, or low-resolution scans.
Rename the source files in sequence before merging, preview the combined PDF, then check the first page, last page, page numbers, duplicate pages, and required signatures.
Work from a copy, remove only the pages that are not needed, save the trimmed file under a new name, and reopen it to confirm no required page was removed.
