Quick answer: to convert a PDF to JPG, open Altto’s PDF to JPG, drop the PDF in, choose Standard (about 150 DPI, for screens) or High (about 220 DPI, for printing), and download. A one-page PDF gives you one JPG; a longer one gives you every page in a single zip.
On a Mac, Preview can export one page at a time: File → Export, then choose JPEG. Windows has no built-in converter.
Why turn a PDF into a JPG?
A PDF is the right format for a document, but plenty of places only want a picture. The usual reasons people convert:
- Social media and messaging. Instagram, and most chat apps, show an image instantly; a PDF becomes an attachment people have to open.
- Slides and documents. Dropping a page of a report or a chart into PowerPoint, Keynote or Google Slides is easiest as an image.
- Websites and listings. A menu, a flyer or a floor plan displays on a web page or marketplace listing as a JPG, not a PDF.
- Upload forms that only accept images. Some application and ID-check forms ask for JPG or PNG, even when what you have is a PDF.
How to convert every page of a PDF to JPG
- Open PDF to JPG and drop in your PDF (one file at a time, up to 60 MB).
- Pick the image quality — more on choosing below.
- Convert and download. Each page is drawn exactly as it looks and saved as a JPG. One page downloads as a single image; several pages arrive together as one zip, so you’re not left with a pile of separate downloads.
It works in any browser, including on an iPhone or Android phone, with no watermark or account. The rendering happens inside your browser tab, so the PDF is never uploaded — worth knowing if the document is a payslip or an ID you need to send as an image.
Standard or High: which quality do you need?
A PDF page doesn’t have a fixed number of pixels — it’s a description of a page that can be drawn at any size. So converting it to an image means choosing a resolution, measured in DPI (dots per inch): how many pixels to use for each inch of the page.
For an A4 page, that works out roughly like this:
| Setting | Approx. resolution | Image size (A4) | Good for |
|---|---|---|---|
| Standard | ~150 DPI | about 1,240 × 1,754 pixels | Viewing on screen, social posts, slides, email, web pages |
| High | ~220 DPI | about 1,820 × 2,570 pixels | Printing, zooming in on small text, detailed diagrams |
Standard is the right choice most of the time: it’s enough detail to read a full page comfortably on a laptop or phone, and the files stay small enough to post or email. Choose High when someone will print the image or needs to zoom into fine print, like a scanned receipt or a technical drawing. The trade-off is file size — a High image has roughly twice as many pixels as a Standard one.
JPG or PNG for PDF pages?
JPG is the format almost everything accepts, and it keeps files small, especially for pages with photos or scans. Its one weakness is sharp black text on a plain white background: look very closely and you may see faint smudges around the letters, because JPG compression is designed for photos. At normal viewing size it’s rarely noticeable.
If a page is mostly text or line drawings and it has to be pin-sharp, PNG avoids those artefacts at the cost of bigger files. Converting a finished JPG to PNG later won’t remove artefacts that are already there, so it’s better to start at High quality if sharpness matters. Our guide to JPG vs PNG goes into the differences.
Other ways to convert a PDF to JPG
Mac: Preview
- Open the PDF in Preview and, if it has several pages, click the page you want in the sidebar.
- Choose File → Export.
- Set Format to JPEG, adjust the quality and resolution if you like, and click Save.
It’s free and private, but it exports one page at a time, so a 20-page document means doing it 20 times. (Automator and Shortcuts can batch it, if you’re comfortable building a workflow.)
Windows
Windows has no built-in PDF-to-image converter. The fallback is to open the PDF, zoom so the page fills the screen, and capture it with the Snipping Tool (Windows key + Shift + S). That works for one page, but the image can only be as sharp as your screen, and it’s slow for more than a couple of pages.
iPhone and Android
Phones have the same screenshot fallback, with the same limits — and a phone screen is narrow, so a full A4 page ends up small and soft. A browser-based converter gives you proper full-page images instead, and PDF to JPG runs in Safari or Chrome on your phone without an app.
Things to know before you convert
- The text becomes part of the picture. A JPG is an image, so you can’t select, copy or search the words in it any more. Keep the PDF as your master copy. If you need to edit the text, convert the PDF to Word instead.
- Scanned PDFs work fine. Each page is rendered exactly as it looks, so a scan converts just as well as a PDF made in Word.
- Only need one or two pages? Convert the whole file and keep the pages you want from the zip, or extract those pages into a smaller PDF first.
- Locked PDFs need unlocking first. If you know the password, Unlock PDF removes it.
