Practical guide
When and how to use Compress PDF
Compress PDF rebuilds document content to reduce storage and upload size where the source allows it. Image-heavy scans usually offer more savings than text-only PDFs that are already optimized.
A smaller file is not automatically a better file: use the lightest reduction that still leaves fine text, signatures, and diagrams readable.
Best used for
- Meeting email attachment limits

Quality checklist
- Compare the before-and-after file sizes
