Use PDF when
You need **one attachment** with ordered pages: invoices, approvals, or policy screenshots. Start from the PDF tools hub — Merge PDF is the usual first step.
Use images when
Reviewers need **pixel-accurate** gallery frames or side-by-side listing shots. Prep with Bulk Resize and Bulk Compress, then send a ZIP or individual files per their instructions.
