Choose pages for the intended handoff
A long PDF may contain cover pages, appendices, or material that does not belong in a preview. Decide which pages are needed and confirm the order of the generated JPG files. A sequence with inconsistent names can be rearranged accidentally when copied or uploaded.
If the PDF includes sensitive pages, inspect the complete page set before sharing. A thumbnail of the first page does not reveal what later pages contain. Keep a copy of the source document and record which page range the image set represents when context matters.
