Table of Contents
A PDF holds a page as instructions: draw this text, in this font, at this position. A JPG holds it as a grid of coloured dots. Saving a PDF as a JPG means choosing how fine that grid should be — and that single decision is what separates a crisp image from a blurry one, or a 90 KB file from a 4 MB one.
Most guides skip straight past it. This one starts with the three steps, then spends the rest of the page on the decision that actually matters.
The short answer
Open the converter
Go to PDF to JPG and drop your file on the page. Nothing is uploaded: the conversion runs inside your browser tab.
Pick a quality
Low (72 DPI), Medium (150 DPI) or High (300 DPI). If you are undecided, Medium is right far more often than High. The next section explains why.
Download
One page gives you one JPG. Several pages give you a ZIP with one image per page, numbered in order.
This particular tool reads the PDF with JavaScript and paints each page onto a canvas in the browser. There is no upload step, so the document never reaches a server — ours or anyone else's. That is worth knowing if the PDF is a contract, a payslip or a medical report.
Why turn a PDF page into a JPG at all
A PDF is the better format for almost everything: it keeps the text selectable, the fonts intact and the file small. So converting to an image is a deliberate downgrade, and it is worth being clear about what you gain:
- It opens anywhere. A messaging app, a photo frame, an old projector, a shop's print terminal — all of them show a JPG without asking questions.
- It cannot be edited by accident. The text stops being text, so nobody can select a figure and change it. This is the usual reason for sending a signed page as an image.
- It drops straight into other documents. A slide, a listing, a forum post, a support ticket.
- It sidesteps broken PDF viewers. Some webmail previews and in-app browsers render PDFs badly. An image always looks the same.
And what you lose: selectable text, searchability, small file size, and any chance of the recipient copying a paragraph out. If any of those matter, send the PDF and stop here.
Three steps, start to finish
Drop the PDF in, and the tool renders a thumbnail of every page so you can see what you are about to export. Choose the pages you want, the quality and the format, then download. On a document of a few pages this takes a second or two; a 200-page report at 300 DPI will take noticeably longer, because your own machine is doing the drawing.
A PDF that asks for a password to open cannot be rendered until it is unlocked. Run it through Unlock PDF first, using the password you already know, then come back.
Which DPI to pick (the part everyone gets wrong)
DPI stands for dots per inch. It decides how many pixels are used to draw one inch of the page, so it sets both the sharpness and the file size. An A4 page is 8.27 by 11.69 inches, which gives these exact dimensions:
| Quality | Pixels for an A4 page | Roughly | Use it for |
|---|---|---|---|
| Low — 72 DPI | 595 × 842 | 0.5 megapixels | Email attachments, chat, a quick visual reference. Body text is legible on screen but soft. |
| Medium — 150 DPI | 1241 × 1754 | 2.2 megapixels | The default answer. Sharp on any screen, prints acceptably on an office printer, still a sensible file size. |
| High — 300 DPI | 2481 × 3507 | 8.7 megapixels | Anything that will be printed properly, or a scan you may want to run OCR on later. |
Here is the part that catches people out. Going from 150 to 300 DPI doubles the dots along each edge, so it quadruples the pixel count — and roughly quadruples the file size. A ten-page document that came to 3 MB at Medium can land near 12 MB at High. If those pages are going into an email or a chat thread, you have just made them harder to send for a sharpness nobody will see on a phone screen.
The honest rule: match the DPI to where the image ends up, not to the idea that more is better.
- It will be looked at on a screen → 150 DPI. A phone or laptop cannot show more detail than that at normal viewing size.
- It will be printed on paper → 300 DPI. Print genuinely resolves the extra detail, and 150 DPI text starts to look furry up close.
- It will be read by OCR software later → 300 DPI. Text recognition needs the extra pixels to tell an e from a c. If that is your goal, our PDF OCR tool reads the PDF directly and saves you the round trip.
- It is going in a chat or an email → 72 or 150 DPI, and check the size before you send.
If the PDF is itself a scan, its pages are already images at whatever resolution the scanner used. Exporting at 300 DPI cannot invent detail that was never captured — it only makes a bigger file of the same blur. Check the original before you reach for High.
JPG, PNG or WebP?
The tool offers all three, and the right one depends on what is on the page.
| Format | Best for | Watch out for |
|---|---|---|
| JPG | Pages with photographs, scans, anything with soft gradients. Smallest files, opens everywhere. | Compression artefacts around sharp black text on white — the faint halo you sometimes see. |
| PNG | Pages that are mostly text, tables, line drawings, logos, charts. Every pixel is kept exactly. | Files are considerably larger than the same page as JPG. |
| WebP | Anything going on a website. Roughly a quarter smaller than JPG at the same visual quality. | Fine in every current browser, but some older desktop software and a few printers still refuse it. |
If the page is a letter, an invoice or a contract — that is, mostly text — PNG will look noticeably cleaner than JPG at the same DPI. If someone asked you for "a JPG", they almost certainly meant "an image", and PNG will do.

Several pages at once
Convert a multi-page PDF and you get a ZIP containing one image per page, numbered so they stay in order. That is usually what you want: separate files you can attach, reorder or send individually.
If instead you need one tall image with every page stacked — for a listing or a single-scroll preview — convert first, then stitch the results together with Images to PDF and export that. It is a detour, but it keeps the page order intact.
And if you only want two or three pages out of fifty, select just those in the page picker. There is no reason to render the whole document.
On a phone
The same page works in a mobile browser — Safari on iPhone, Chrome on Android — with two things worth knowing.
First, the rendering happens on the phone, so a long document at High quality will be slow and will warm up the handset. Medium is a kinder choice on mobile.
Second, where the file lands depends on the browser. On iPhone the ZIP goes to the Files app, under Downloads, and you tap it to expand it. On Android it goes to the Downloads folder and your file manager will open it. If you only need one page, pick that page before converting and you will get a plain JPG straight into your photos instead of a ZIP to unpack.
When the result looks wrong
The text is blurry
Either the DPI is too low for how closely you are looking, or the PDF was a scan to begin with. Try Medium or High; if it is still soft, the original has no more detail to give.
The file is enormous
You are almost certainly on High. Drop to Medium and the file falls to roughly a quarter of the size, with no visible difference on a screen.
Black text has a grey halo
That is JPG compression on sharp edges. Switch the output format to PNG and it disappears.
Nothing happens at all
The PDF is probably password protected, or damaged. Unlock it first, or run it through Repair PDF.

Open PDF to JPGFrequently asked questions
Does converting a PDF to JPG lose quality?
Yes, and unavoidably so. The text stops being text and becomes pixels, so it can no longer be selected, searched or resized without softening. Choosing a higher DPI reduces how visible that is, but it does not undo it. Keep the original PDF.
What DPI should I use for printing?
300 DPI. That is the long-standing standard for print, and it is the only setting where the extra file size buys you something you can actually see on paper.
Can I turn the JPG back into a PDF?
You can wrap it back into a PDF with JPG to PDF, but the text will still be an image. To get selectable text back you would need to run OCR on it, and that is a recognition step with its own error rate — not a true reversal.
How do I convert just one page?
Select that page in the picker before converting. You will get a single JPG rather than a ZIP.
Is there a file size or page limit?
There is no fixed limit, because the work happens on your own machine. The practical ceiling is your device's memory: a very long document at 300 DPI can exhaust a phone's RAM. If a large file stalls, convert it in batches of pages.
Are my files uploaded anywhere?
Not for this tool. The PDF is read and rendered entirely in your browser, so it never travels to a server. Some of our other tools do need to process on our servers, and each one says so on its own page.
In short
Saving a PDF as a JPG is three clicks. Getting a good result is one decision: 150 DPI for anything that will be looked at on a screen, 300 DPI for anything that will be printed or read by OCR. Pick PNG over JPG when the page is mostly text, and keep the original PDF whatever you do — the conversion only goes one way.
