You're staring at a PDF. Maybe it’s a concert ticket, a signed contract, or a beautiful design layout, and you just need it to be a simple image file. Why? Because some websites won't let you upload a PDF to a profile picture slot, or maybe you want to drop a specific page into a PowerPoint without the clunky PDF container. Honestly, figuring out how to convert PDF to JPG on Mac is one of those tasks that sounds like it should be a single click, but Apple hides the best ways in plain sight.
Stop looking for a "Convert" button in the file menu. It isn't there.
Most people immediately head to the App Store and download some "Free PDF Converter" that ends up being a subscription trap or, worse, a privacy nightmare that uploads your sensitive documents to a random server in another country. You don't need that. Your Mac already has the horsepower to do this natively. Whether you have one page or a hundred, the tools are already sitting in your Applications folder.
Preview is the secret MVP of macOS
If you double-click a PDF, it probably opens in Preview. Most of us treat Preview like a basic viewer, sort of like a digital piece of glass. But it’s actually a surprisingly beefy image editor.
To turn a single page into a JPG, just go to File > Export. Look at the "Format" dropdown menu at the bottom of the dialogue box. Switch it from PDF to JPEG. You’ll see a quality slider. Cranking it to the right makes the file huge but crisp; keeping it in the middle is usually fine for a quick email attachment.
But what if you have a 50-page document? Exporting each page one by one is a soul-crushing waste of time.
If you select all the thumbnails in the sidebar (Cmd+A) and try to export, Preview sometimes gets confused and only saves the first page. It's a weird quirk of the software. To get around this, you actually want to use the "Export Selected Images" function or, better yet, lean on the automation tools Apple built for pros.
The "Quick Action" trick for speed demons
MacOS Monterey and everything after it (Ventura, Sonoma, and the newer builds) have this feature called Quick Actions. It is, quite literally, the fastest way to convert PDF to JPG on Mac.
Find your file in the Finder. Right-click it. Hover over "Quick Actions." You might see "Convert Image" right there. If you don't, you can build a 5-second workflow in Automator or the Shortcuts app that adds this to your right-click menu forever.
Building a "Convert to JPG" Shortcut
- Open the Shortcuts app (it’s in your Dock or Applications).
- Hit the "+" to make a new one.
- Search for "Select File" or just set it to accept "Shortcut Input."
- Add the action "Change Type" or "Convert Image."
- Set the target format to JPEG.
- In the shortcut settings (the little sliders icon), check the box that says "Use as Quick Action."
Now, whenever you have a PDF, you don't even have to open it. Right-click, hit your new shortcut, and boom—JPGs appear in the same folder. It’s basically magic for people who deal with dozens of invoices or receipts daily.
Why the resolution matters (and why your JPGs look blurry)
Ever converted a PDF and realized the text looks like it was dragged through a puddle? That’s a DPI issue. PDF files are often vector-based, meaning they stay sharp no matter how much you zoom in. JPGs are rasterized. They are made of fixed pixels.
When you use the Preview export method, look at the Resolution field. It usually defaults to 72 or 150 pixels/inch. If you’re planning to print that JPG or if it contains small fine print, you need to bump that to 300.
High resolution = larger file size.
Low resolution = muddy text.
Find the middle ground. For most web uploads, 150 is the "Goldilocks" zone. If you're sending a photo to a professional lab, don't settle for anything less than 300.
Adobe Acrobat: The pro (and expensive) route
If you’re a creative professional, you probably already pay for Adobe Creative Cloud. Adobe Acrobat Pro is the undisputed king of document manipulation, though its interface feels like it was designed by a committee that loves sub-menus.
In Acrobat, you go to File > Export To > Image > JPEG.
The benefit here isn't just the conversion; it's the control. Acrobat lets you strip out metadata, manage color profiles (CMYK vs. RGB), and handle transparency in ways Preview can't quite manage. If you’re converting a PDF for a high-end magazine ad, use Acrobat. If you’re converting a scanned recipe for your grandma, Acrobat is overkill.
Dealing with the "Multi-Page" headache
Let's be real: the biggest pain point is when you have a 10-page PDF and you want 10 separate JPGs.
By default, most "Export" functions try to turn the whole PDF into one file, which doesn't work for JPGs (since JPG doesn't support pages). You end up with just the first page.
If you aren't comfortable with the Shortcuts app mentioned earlier, the easiest "non-techy" workaround is to use the Print to PDF trick in reverse, but that's messy. Instead, use the Automator app.

- Launch Automator.
- Choose "Workflow."
- Drag your PDF into the window.
- Search for "Render PDF Pages as Images."
- Drag that action into the flow.
- Select "JPEG" as the output.
- Add a "Move Finder Items" action at the end so you can tell it where to save the results.
Click "Run" at the top right. It will churn through the document and spit out a numbered list of images. It’s a bit 2010s-style tech, but it works every single time without fail.
Online converters: A word of caution
We’ve all used them. SmallPDF, ILovePDF, etc. They are convenient. You drag a file into a browser, and a few seconds later, you download a zip.
But think about what's in that PDF. If it's a bank statement, a medical record, or a contract with your Social Security number on it, do you really want that sitting on a third-party server? Even if they promise they delete files after an hour, breaches happen.
Since your Mac can convert PDF to JPG locally without an internet connection, there's almost no reason to risk your data on a web-based converter unless you're on a borrowed computer.
Summary of the best methods
| Method | Best For | Effort Level |
|---|---|---|
| Preview Export | Single pages or small files | Very Low |
| Quick Actions | Speed and repetitive tasks | Medium (Setup required) |
| Automator | Massively long documents | High |
| Adobe Acrobat | Professional print work | Low (if you already own it) |
Actionable Next Steps
To get your files organized and converted right now, start with the simplest path:
- Open your PDF in Preview and try the File > Export method first to see if the quality meets your needs.
- Check your resolution. If the text is fuzzy, re-export at 300 DPI.
- Set up a Shortcut. If you find yourself doing this more than once a week, spend the three minutes to build a "Quick Action" in the Shortcuts app. It will save you hours over the course of a year.
- Keep it local. Avoid uploading sensitive documents to free online conversion websites to protect your privacy.
By using the tools baked into macOS, you keep your data private, maintain higher image quality, and save money on unnecessary software subscriptions.
