How2 Mac: Preview Tricks in 5 Minutes Flat
Preview is not just an image viewer — it signs PDFs, merges documents and shrinks files in seconds. Learn five tricks in five minutes and stop opening heavy apps for tiny jobs.
1. Sign, Mark Up and Fill PDFs Without Extra Apps
Open any PDF in Preview, click the Markup toolbar, and you can draw, add text boxes, highlight and sign. Create a signature once with your trackpad or camera, then reuse it on every form. It is the fastest way to return a signed document from your Mac.
- Show Markup Toolbar from the View menu
- Add your signature under Annotate > Signatures
- Use text boxes for dates and checkboxes
Pair this with freeing your Mac storage so big PDFs never pile up.
2. Combine, Reorder and Trim Pages Visually
Show Thumbnails, then drag pages between open PDFs to combine them, drag thumbnails to reorder, and delete pages you do not need. Preview treats each thumbnail like a card you can move — no separate merge tool required.
This is perfect for receipts, contracts and school forms. Save a copy first, then build the clean final version.
Preview Tricks at a Glance
| Job | Preview Trick | Time |
|---|---|---|
| Sign a PDF | Markup > Signature | 30 seconds |
| Merge PDFs | Drag thumbnails together | 1 minute |
| Shrink an image | Tools > Adjust Size | 30 seconds |
| Remove a background | Instant Alpha tool | 1 minute |
Organize the results with Finder Tags so you can find them later.
3. Resize, Convert and Clean Up Images Fast
Use Tools > Adjust Size to resize for email or the web, and File > Export to convert between JPEG, PNG and PDF. The Instant Alpha tool in Markup can lift a simple background away from a logo or product shot.
Before you export a large library, back it up — our Time Machine guide shows the safe routine.
Your 5-Minute Preview Routine
Open Preview first for PDFs and images. Sign it, merge it, resize it, export it — most everyday jobs are done before a heavier app would even finish launching.
