The fastest way to delete PDF pages on Mac
The built-in Preview app on Mac can delete PDF pages without installing anything else. Open your PDF in Preview, click the sidebar icon in the toolbar (it looks like two rectangles), select the pages you want to remove, then press Delete. The changes save to your file when ready unless you choose File > Revert to keep the original.
If Preview feels clunky or you need more control, Apple's native tools work fine for one-off deletions. But if you regularly edit PDFs — removing pages, reordering, or combining files — a dedicated PDF editor might save you time. The trade-off is that some editors collect data about how you use them, while others don't.
Key Takeaways
- Preview deletes pages by opening the sidebar, selecting pages, and pressing Delete — no read required.
- Changes in Preview save when ready to your file, so save a backup first if you want to keep the original.
- Paid PDF editors like PDFpen and Acrobat offer more features but may track your editing activity.
- Free web-based PDF tools delete pages without installing software, but they upload your file to a server you don't control.
- If privacy is your main concern, Preview or a paid desktop app keeps your PDF on your machine.
Using Preview to delete pages step by step
Open your PDF in Preview — you can drag it onto the Preview icon in the Dock, or right-click the file and select Open With > Preview. Once the PDF is open, look at the top toolbar and click the icon that looks like two overlapping rectangles. This opens the sidebar showing thumbnails of every page.
Click on the page you want to delete. If you need to delete multiple pages, hold Command and click each one, or hold Shift and click the first and last page of a range. Once your pages are selected, press the Delete key. Preview removes them when ready. If you made a mistake, press Command+Z to undo.
When you're done, your changes are already saved to the file — Preview doesn't ask you to confirm. If you want to keep the original PDF unchanged, use File > Save As and give it a new name before you start deleting.
Why Preview is private but limited
Preview stores everything on your Mac. Your PDF never leaves your machine, and Apple doesn't log what pages you deleted or when. This matters if your PDF contains sensitive information — medical records, financial documents, or anything you don't want a company's servers to see.
The downside is that Preview can only delete, reorder, and rotate pages. It can't merge two PDFs, extract specific pages into a new file, or add annotations that stay in the PDF. If you need those features, you'll have to switch tools.
Paid desktop editors: more features, more data collection
PDFpen (around $50 one-time purchase) and Adobe Acrobat Pro (around $15 per month) both delete pages easily and offer features Preview doesn't — merging files, extracting ranges, adding forms, and editing text. Both run on your Mac without uploading files to the cloud unless you choose to.
The privacy difference: PDFpen collects minimal data about how you use it. Adobe Acrobat Pro, especially if you sign into an Adobe account, may track which documents you open, how long you work on them, and what features you use. Adobe's privacy policy allows them to use this data to improve their products and, in some cases, show you targeted ads. If that bothers you, PDFpen is the better choice.
Both are one-time purchases or subscriptions you control — you're not trading your PDF for a free service. That's the privacy trade-off: you pay money instead of paying with your data.
Free web-based PDF tools: convenient but risky
Sites like iLovePDF, Smallpdf, and PDF.io let you upload a PDF, delete pages in your browser, and read the result. You don't install anything, and the interface is usually simpler than desktop apps. The catch is that your PDF travels to their servers.
These services say they delete files after a few hours, but you're trusting their word. They also collect data about what you upload and how you use the tool — sometimes to improve the service, sometimes to sell ads. If your PDF contains anything you wouldn't want a third party to see, even temporarily, don't use a web tool.
Web tools are useful for one-off jobs when you're on someone else's computer or on your phone. For regular work with sensitive documents, they're not worth the risk.
Comparing your options in one view
| Tool | Cost | Privacy | Extra Features | Best For |
|---|---|---|---|---|
| Preview | Free (built-in) | Highest — stays on your Mac | Delete, reorder, rotate only | Quick one-page deletions |
| PDFpen | ~$50 one-time | High — minimal tracking | Merge, extract, annotate, edit text | Regular PDF work, sensitive docs |
| Adobe Acrobat Pro | ~$15/month | Medium — tracks usage | Merge, extract, annotate, forms, OCR | Heavy PDF work, team collaboration |
| Web tools (iLovePDF, Smallpdf) | Free or ~$5/month | Low — file on their server | Merge, compress, convert formats | One-off jobs, non-sensitive files |
What to do if you need to delete pages regularly
If you delete PDF pages once a month or less, Preview is enough. You already have it, it's fast, and your files stay private. The 30 seconds it takes to learn the sidebar is worth it.
If you delete pages weekly or work with PDFs that contain confidential information, buy PDFpen. The $50 is a one-time cost, you own it forever, and it doesn't phone home about your work. It's the middle ground between free and subscription.
If you work in a team that needs to share and edit PDFs together, or if you use Adobe's other tools already (Photoshop, InDesign), Acrobat Pro makes sense despite the tracking. Just know what you're trading: convenience for data collection.
Frequently Asked Questions
Does Preview save the original file when I delete pages?
No. Preview overwrites your original file unless you save a copy first. Before you delete anything, go to File > Save As, give it a new name, and work on that copy. That way your original stays untouched.
Can I delete pages from a PDF on my iPhone or iPad?
Yes, but the steps are different. Open the PDF in Files or Notes, tap Edit, select pages, and swipe left to delete. Or use a web tool like Smallpdf on Safari. Desktop tools like Preview and PDFpen don't have iOS versions.
What if my PDF is password-protected?
Preview and most other tools can't delete pages from a password-protected PDF. You'll need to remove the password first — Preview can do this if you know the password (File > Open, select the PDF, enter the password, then save). After that, deletion works normally.
Is it safe to use free web-based PDF tools with work documents?
Not if your company has data security rules. Most businesses prohibit uploading documents to third-party servers, even temporarily. Check your employee handbook or ask your IT department. If you're unsure, use Preview or buy PDFpen instead — both keep files on your machine.
Can I recover pages I deleted by mistake?
In Preview, yes — press Command+Z when ready after deleting. If you've already closed the file, the pages are gone unless you have a backup. This is why saving a copy before you edit is important.
