📏
Always compress your PDF before emailing — most email platforms cap attachments at 25 MB. A smaller file also opens faster on mobile devices.

When working with multiple files, merge them into one PDF first, then apply compression. You'll get better size reduction than compressing files individually.

After processing, open the result at 100% zoom to confirm text sharpness and image quality before submitting to a portal or sharing with clients.
