How to turn a PDF into images (JPG or PNG)

Sometimes a PDF is the wrong shape for what you’re doing. You want to post a page on Instagram, drop it into a slide, or show it on a web page, and none of those places want a PDF. They want an image. So you need to turn each page into a JPG or a PNG.

This is easy to do, and it’s worth understanding the two small decisions that change how the result looks: which format you pick, and what resolution you export at.

When you actually need images

A PDF is great for documents you want to keep intact: contracts, reports, anything meant to be printed or read as a file. But the moment you want a page to live somewhere visual, it gets awkward.

A few cases where images win:

• Social media. Instagram, X, LinkedIn carousels, and most feeds take images, not PDFs. One page becomes one post.
• Slides. Pasting a PDF page into a presentation is fiddly. A clean PNG of that page drops straight in and scales without fuss.
• Web pages. You can embed a PDF, but a plain image loads faster and shows up the same way in every browser.
• Quick previews. Sometimes you just want to send someone a screenshot of page 3 without handing over the whole file.

In all of these, the page stops being a document and starts being a picture. That’s the job.

JPG or PNG?

These two formats are built for different things, and picking the right one saves you from a blurry or bloated file.

JPG is made for photographs. It compresses by throwing away detail your eye barely notices, which keeps the file small. The downside shows up on sharp edges: text and thin lines can pick up faint smudges, called artifacts, around them. JPG also can’t do transparency, so anything see-through gets filled with a solid color.

Reach for JPG when the page is mostly photos or rich color images, like a scanned magazine spread or a brochure. The file stays light and the photos look fine.

PNG keeps every pixel exactly as it is. Text stays crisp, lines stay clean, and it supports transparency, so you can have a page with no background. The cost is size: a PNG of a photo-heavy page can be several times bigger than the JPG.

Reach for PNG when the page is text, diagrams, charts, screenshots, or a logo. Anything with sharp edges looks better in PNG, and if you need a transparent background, PNG is your only choice of the two.

Quick rule: photo-heavy page, use JPG. Text or graphics, use PNG.

Picking the right resolution (DPI)

Resolution is how much detail you capture, usually measured in DPI (dots per inch). Higher DPI means a sharper, bigger image. Lower DPI means a smaller, softer one. There’s no single right number, it depends on where the image is going.

• 72 to 96 DPI is plenty for screens. Web pages, social posts, and on-screen slides all live at screen resolution, so going higher just makes a heavier file with no visible gain.
• 150 DPI is a comfortable middle. Good if you might zoom in a bit, or if you’re not sure yet where the image will end up.
• 300 DPI is print quality. Use it only if the image is actually going to paper, like a flyer or a poster. On a screen you won’t see the difference, you’ll just wait longer for it to load.

When in doubt, 150 DPI covers most needs. Bump it to 300 only when you’re printing.

Doing it without uploading the PDF

Here’s the part that matters if the PDF is private. The files.co PDF to images tool runs the whole conversion in your browser. Your file is read into memory on your own device, each page is rendered to a JPG or PNG right there, and the images download to your machine. The PDF never goes to a server.

That means a payslip, a signed contract, or a draft nobody’s meant to see stays on your computer. Load the page once and it even works offline. If you want to check for yourself, open DevTools (F12), go to the Network tab, and run a conversion. You’ll see the page load and then nothing while the work happens. No upload.

And if you ever need the trip in reverse, stitching a stack of photos or scans back into a single document, the Images to PDF tool does that the same way, all on your device.

So: pick JPG for photos and PNG for text or transparency, choose 150 DPI unless you’re printing, and let your browser do the rest.
