Convert PDF Pages to Images
Render any page of a PDF as an image at the resolution you need — 72 DPI for a quick preview, 300 for print. You pick which pages, the output format, and the quality. The rendering engine runs inside this browser tab with its worker served from this site rather than a third-party CDN, so your document is never transmitted anywhere.
Use this without the search next time. Prathom Workbench puts Prathom's tools in your toolbar.

How to use PDF to JPG
- 1
Open the PDF
Drop the file in. It is parsed immediately and the page count shown, so you know what you are working with.
- 2
Choose the pages
Leave the box blank for every page, or list numbers and ranges such as "1-5, 12". The odd and even keywords work too.
- 3
Set resolution and format
150 DPI suits most uses. Choose PNG when the pages are mostly text and JPEG when they are mostly photographs.
- 4
Convert and download
Each page appears with a thumbnail and its exact dimensions. Save them individually or take the set as one ZIP.
How it works
A PDF page is a set of drawing instructions in a coordinate space of 72 units to the inch. Rendering means executing those instructions onto a canvas — laying out text with the correct fonts, stroking and filling vector paths, and decoding and placing embedded images.
The resolution you choose becomes a scale factor of DPI divided by 72. At 72 DPI the scale is 1 and one canvas pixel equals one PDF point, which is why an A4 page comes out 595 pixels wide. At 300 DPI the scale is roughly 4.17 and the same page becomes about 2480 pixels.
Two details the tool handles that are easy to get wrong:
The white background. A PDF page has no background of its own. Rendering onto an untouched canvas gives a transparent PNG and, far worse, a JPEG whose unpainted areas come out black — because JPEG has no transparency and undefined pixels default to transparent black. The canvas is filled with white first.
The canvas ceiling. Browsers cap canvas dimensions and total pixels, and exceeding the cap does not throw an error — it silently produces a blank canvas. A large-format page at 300 DPI can reach that limit, so the size is checked before rendering and the request is refused with an explanation rather than succeeding into an empty image.
The parser itself runs in a Web Worker, which keeps a long document from freezing the tab, and the tool yields between pages so the progress bar can actually repaint.
When you'd use this
Putting a page into a slide, a document, or a message, where an image drops in and a PDF does not.
Posting a page somewhere that will not accept PDF uploads — most social platforms, many forums, plenty of ticketing systems.
Creating thumbnails or previews of a document set.
Getting a page into an image editor to annotate, redact, or crop it, since most image tools cannot open a PDF directly.
The resolution trade, in one paragraph
Doubling the DPI doubles each dimension and therefore quadruples the pixel count and roughly the file size. A 40-page document at 300 DPI can easily reach a hundred megabytes as PNG. If you are converting a whole document, start at 150 and only go higher for the specific pages that need it — which is exactly why the page selection box exists next to the resolution control.
Examples
A single A4 page for a slide
An A4 page is 595 by 842 points, and a point is one seventy-second of an inch. At 150 DPI that scales by 150/72, giving 1240 by 1754 pixels. Knowing that relationship is how you predict the output size before converting rather than guessing at a quality slider.
A whole document at preview resolution
72 DPI renders at the PDF's own coordinate scale, meaning one pixel per point, which is why the numbers match the page dimensions exactly. This is the right setting for thumbnails and contact sheets and the wrong one for anything anyone will read.
Frequently asked questions
What resolution should I choose?
150 DPI for most purposes — readable on screen, reasonable file size, and good enough for a document that might be printed casually. Choose 300 for anything going to a printer properly. Choose 72 only for thumbnails and previews, because a page rendered at 72 DPI is roughly 600 pixels wide and body text on it is not comfortably legible.
Should I pick JPEG or PNG?
PNG for pages that are mostly text, diagrams, or line art — it keeps edges perfectly crisp and often produces a smaller file for flat content. JPEG for pages dominated by photographs, where it will be several times smaller with no visible difference. A page with text over a photograph is the awkward case; PNG is the safer choice there because JPEG haloing around text is noticeable.
Does this extract the images that are inside the PDF?
No, and the distinction matters. This renders each page as it appears — text, vectors, photographs and all — into a single flat image. Pulling out the original embedded photographs at their own resolution is a different operation, and gives you the pictures without the surrounding page. If you want the page as it looks, this is the right tool.
Why did a page come out blank or with missing text?
Most often a font problem. The renderer here is served with the standard font data and character maps it needs, which covers the usual causes. If text is still missing, the PDF may reference a font it neither embeds nor names correctly. Very occasionally a page uses a feature the renderer handles imperfectly; comparing against how the page looks in a PDF reader will tell you quickly.
Is my PDF uploaded to be rendered?
Yes, and this changed in August 2026. The tool used to render in your browser with a JavaScript engine served from this site. It now uploads the file to our own servers, renders the pages there with poppler, and deletes the upload immediately afterwards. No third party is involved at any point and no external CDN is used. We moved it because a PDF renderer is a large library, and shipping one to every visitor made the page slower for everyone — including people who only came to read it. If you would rather nothing left your machine at all, exporting from a desktop PDF reader is the better choice for that file.

- This PDF Kept Every Pixel and Still Came Out Looking WorstCompress a PDF and the obvious way to check what happened is to look at the resolution of the images inside. It is the number every tool reports and the one every comparison uses. It is also, on its own, close to useless — here is a file that kept every single pixel at full resolution and looked worse than one that threw three quarters of them away.
- What "Compress PDF" Actually Removes, Preset by PresetNearly every "compress PDF" tool is Ghostscript underneath, running one of five named presets. Those presets do very different things, the differences are not what their names suggest, and the one that produced the smallest file also produced the worst-looking page. Here is all five measured on the same document.
- How to Make a PDF Smaller Without Making It Blurry“Compress PDF” can mean two very different operations: cleaning the file's structure or throwing away visual information. Knowing which one you need is the difference between a smaller document that still prints well and a blurry scan that only looks acceptable at thumbnail size.
