If your PDF is a scanned document with huge images, Preview can trim the fat. Open the PDF, click on “View” > “Thumbnails.” Select an image-heavy page (like a photo). Press Command + A to select all pages, then go to “Tools” > “Adjust Size.”
Drop the dimensions by half. Half! Then hit “OK.” Yes, your selfie will look pixelated, but your PDF now weighs less than a feather. If you only need the text, just delete the image pages entirely. Harsh? Maybe. Efficient? Absolutely.
The Nuclear Option: Convert to a .zip File
If all else fails—and your PDF is still the size of Jupiter—right-click it and select “Compress” from the menu. Your Mac will spit out a .zip file. It’s not really smaller, but it acts smaller when you email it. Plus, it’s a great conversation starter: “Why did you send me a zip? I thought PDFs were already compressed?” You can just shrug and say, “Mac magic.”
Honestly, the best trick is planning ahead. Before you even create the PDF, save your original document at a lower quality. In Word or Pages, use “Export as PDF” and choose “Minimum File Size” under quality. Future you will thank past you.
So there you have it. Grab your coffee, pick one of these methods, and give that bloated PDF a spa day. If you still can’t fit it in an email? Maybe it’s time to break the news that your 200-page portfolio of cat photos might need its own cloud storage. You’re welcome.
