Why Converting PDF to JPG Is Different from Other Conversions
Most file conversions swap one container for another. Turning a PNG into a JPG keeps the same pixels and changes how they are stored. Converting PDF to JPG is not like that at all.
A PDF Page Is Vector Instructions, a JPG Is Pixels
A PDF page is a set of drawing instructions with no fixed pixel size; a JPG is a fixed grid of pixels. Converting PDF to JPG therefore always means choosing a resolution — nothing is "preserved".
Open a PDF in a text editor and you will find commands, not pictures: set this font, move to these coordinates, draw this curve, fill this shape. The page is described, not painted. It can be rendered at any size without losing sharpness, which is exactly what makes it a good format for documents.
A JPG has none of that flexibility. It is a rectangle of coloured dots — say 1275 across and 1650 down — and that is all it will ever be. Scale it up and the dots get bigger.
Why Resolution Has to Be Chosen, Not Preserved
So when you convert PDF to JPG, something has to decide how many dots to use. That decision is the DPI setting, and it is the single most important choice on this page. Too low, and small text becomes a grey smear. Too high, and a ten-page document turns into 100 MB of images nobody can email.
Many online converters hide this choice and pick a number for you, usually a low one. This tool puts it front and centre, with a live estimate of the pixel size and file size so the number means something.
Rendering a Page vs Extracting the Images Inside It
There is a second distinction that trips people up. "Get JPGs out of a PDF" can mean two completely different things.
Rendering a PDF page to JPG and extracting the images embedded in a PDF are two different operations: the first gives you a picture of the page, the second gives you the original photos placed on it.
If a brochure has a photograph on page 3, rendering the page gives you the photo plus the headline, the body text and the white margins around it, at whatever DPI you chose. Extracting gives you the photograph alone, at the exact pixel dimensions it was stored in — often much larger than the rendered page.
Which One You Actually Need
Want to share a page, insert it into a slide, or read it on a phone? Render the page. Want the product shots out of a catalogue, or the figures out of a report? Extract the images. This converter does both, and you switch between them with one control.
What This PDF to JPG Converter Does
This tool opens a PDF in your browser, lets you pick pages on a visual contact sheet, renders each one to a JPG at the DPI you choose, and hands the results back as single files or a ZIP — without ever sending the document to a server.
Everything Happens in Your Browser
The rendering engine is pdf.js, the same open-source library Firefox uses to display PDFs. It runs inside your tab. Drop a file, and it is read into memory on your machine; the page images are drawn onto a canvas on your machine; the JPG bytes are encoded on your machine.
You can confirm this yourself: open your browser's developer tools, watch the Network panel, and convert a file. Nothing is sent.
That has a practical consequence beyond privacy. There is no upload to wait for, no queue, no "2 conversions left today". A 300-page PDF takes as long as your computer needs to draw 300 pages, and not a second longer.
What You Get: One JPG per Page
In the default mode, every selected page becomes one image named after the source file — report-page-01.jpg, report-page-02.jpg and so on — so the files sort correctly wherever you put them. Each card in the results shows the pixel size and file size before you download.
Switch to Extract images and the output becomes one file per embedded picture instead, tagged with the page it came from. Both modes offer JPG or PNG output.
How to Convert PDF to JPG in 3 Steps
Drop your PDF
Drag the file onto the dashed area or click to browse. Password-protected PDFs are supported — you will be asked for the password, and it never leaves the page either. Within a second or two the contact sheet appears with a thumbnail of every page.
Pick pages and resolution
Every page starts selected. Click thumbnails to toggle them, or type a range such as 1-3, 7 in the Pages box — the two stay in sync. Choose 72, 150 or 300 DPI and watch the estimated pixel size update. To pull out the embedded photographs instead, switch the mode to Extract images.
Download a single JPG or a ZIP
Press Convert. Pages appear in the results grid as they finish, each with its own download button. When the run completes, Download ZIP bundles everything into one archive with clean, sortable file names.
Drop a PDF. It is opened locally, in your browser, and never uploaded.
Click pages on the contact sheet or type a range. Pick 72, 150 or 300 DPI — or switch to Extract images.
Download any single image, or every image at once as a ZIP.
Picking the Right DPI and Quality
Two settings decide how a PDF to JPG conversion turns out: the resolution and the JPG quality. They affect different things, and it helps to understand both before you pick.
DPI Explained in One Table
DPI stands for dots per inch. A PDF page has a physical size — a US Letter page is 8.5 by 11 inches — and the DPI decides how many pixels each of those inches gets.
At 150 DPI, a US Letter page becomes a 1275 × 1650 pixel JPG; at 300 DPI it becomes 2550 × 3300 pixels — four times the pixels and roughly four times the file size.
Screen, Web, Print — Which Setting for Which Job
Use 72 DPI when the image will only ever be a small preview: a thumbnail in a file list, a quick look on a chat app. Text is readable at full size but not crisp.
Use 150 DPI — the default — for almost everything else: sharing, slides, reading on a phone or tablet, posting to a website. It is sharp enough to read footnotes and small enough to send.
Use 300 DPI when the JPG is going to be printed, placed in a print layout, or zoomed into. Expect files of 1–3 MB per page for text documents and more for pages with photos.
The custom box accepts anything from 50 to 600 DPI. Very large pages at very high DPI can exceed what a browser canvas can hold; if that happens the tool lowers the DPI automatically and marks the result, rather than failing.
JPG Quality vs File Size
Quality is a separate dial. DPI decides how many pixels there are; quality decides how aggressively those pixels are compressed. The slider runs from 60 to 100.
Why 90 Is the Sweet Spot
File size does not grow evenly with quality. From 60 to 90 it climbs gently. Above 90 it climbs steeply, and above 95 it roughly doubles again while looking identical to the eye. For a rendered document page, 90 is where the curve bends — it is the default here, and there is rarely a reason to go higher.
Going lower is sometimes worth it. If the images must fit an upload limit, drop to 80 first; small text is still legible and the files shrink by a third.
When to Choose PNG Instead of JPG
JPG is the right output for most pages, and it is what the keyword in your search bar asked for. But JPG cannot store transparency and it softens hard edges slightly. Pick PNG when the page is line art, a diagram, a screenshot, or a scanned form where you want every edge exact — or when you need a transparent background. The trade-off is size: PNG page images are typically two to four times larger. If PNG is what you mainly need, the dedicated PDF to PNG converter defaults to it.
DPI Reference for a US Letter Page
| Setting | Pixels (8.5 × 11 in) | Typical JPG size at q90 | Best for |
|---|---|---|---|
| 72 DPI | 612 × 792 | 60–150 KB | Thumbnails, quick previews, chat |
| 150 DPI | 1275 × 1650 | 200–500 KB | Sharing, slides, phones, web pages |
| 300 DPI | 2550 × 3300 | 1–3 MB | Printing, zooming, archival |
| 600 DPI | 5100 × 6600 | 4–10 MB | Fine line art for professional print |
What You Can Do With Your PDF as JPG
People rarely convert PDF to JPG for its own sake. The image is a means to an end, and the end decides the settings.
Share a Page on Social Media or Chat
Most messaging apps and social networks preview an image instantly but treat a PDF as an attachment to be downloaded. A single page saved as JPG at 150 DPI shows up inline, readable, on every device. Select just that page, convert, and send.
Insert a PDF Page into Slides or Documents
Presentation software will not embed a PDF page directly, but it will place an image. Render the page at 150 DPI for on-screen decks, or 300 DPI if the deck will be printed, then drag the JPG onto the slide. The same trick works for Word, Google Docs and email signatures.
Make a Contract or ID Page Readable on Any Device
A scanned lease, a signed agreement, a passport page — these are exactly the files you should not upload to a random converter. Rendering them to JPG in the browser keeps them on your machine while giving you a format that opens anywhere, including on phones that struggle with multi-page PDFs.
Build Thumbnails for a Document Library
Intranets, course portals and download pages look far better with a picture of each document's first page. Select page 1 only, render at 72 DPI, and you get a small, fast-loading thumbnail. Run a whole folder of PDFs through and name the outputs consistently.
Pull the Photographs Out of a Catalogue or Report
This is the job for the Extract images mode. Select the pages, and every embedded photograph comes out on its own, at the pixel size it was stored — no headline, no margins, no re-rendering. Product shots from a supplier PDF, figures from a paper, scans from an archive: they arrive as clean files ready for the next step.
Browser-Based vs Server-Based PDF to JPG Converters
Almost every free PDF to JPG converter you will find works the same way: you upload the file, a server renders it, you download the result, and the server deletes its copy — eventually. Published retention windows run from one hour to twenty-four. The approach is not wrong, but it carries costs that a browser-based tool does not.
Where a Server Tool Still Wins
Honesty first. A server has more memory and a faster processor than a phone, so on a very old device a server-based converter will finish a 500-page document sooner. Some server tools also offer OCR, which turns scanned pages into searchable text; this tool does not attempt that.
Extracting Embedded Images at Original Resolution
Until recently this was the other advantage of server tools — the ability to pull the original images out of the file rather than re-render the page. That gap is closed: the Extract images mode here does the same thing in the browser, reading each picture's stored pixels directly from the PDF.
Why Sensitive Documents Should Stay Offline
Contracts, medical records, financial statements, anything with a signature or an ID number: once uploaded, the file is on a machine you do not control, under a privacy policy you probably did not read, for as long as the operator says. A browser-based converter removes the question entirely. There is no copy to delete because there never was one.
The quota question is related. Server time costs money, so free tiers ration it: two files a day, ten pages per file, a sign-up wall after the first conversion. Rendering on your own device costs the operator nothing, which is why this page can offer unlimited pages and unlimited files without an account.
Feature Comparison

What to Do With the Images Next
A PDF to JPG conversion is usually the first step, not the last. The images you just made are ordinary JPGs, and every other tool on this site works on them without another upload.
If the files need to fit an email or a form, run them through the compress to 200 KB tool, or compress JPEG for finer control. If only part of a page matters, crop the image down to it. If a platform demands a specific width, resize the image to match.
Need to go the other way? Once you have edited or reordered the page images, JPG to PDF rebuilds them into a document, and merge PDF combines that with other files. And if what you really wanted was the words rather than the pictures, PDF to Word extracts the text layer instead.
Every one of those tools shares the same rule as this one: the file stays in your browser from start to finish.
