Turn a PDF into images

Every page becomes its own picture, at a resolution that suits what you need it for. The document is rendered in this browser tab and is never uploaded.

How it works

A PDF page is a set of drawing instructions, not a picture. That is what makes text in a PDF selectable and what makes the file scale to any size without going blurry. It is also why a PDF is awkward the moment something wants an image instead: a marketplace listing, a slide, a chat window that will preview a photo but not a document, a form that says JPG.

This runs the same rendering a PDF viewer does, then saves the result. Each page is drawn onto a canvas at the resolution you asked for and encoded, one page at a time. Rendering happens through pdf.js in a worker, so the tab stays responsive on a long document, and each page is released before the next one starts rather than holding a hundred of them in memory at once.

The choice on offer is what the pictures are for, because that is the thing you actually know. Screen or email renders at 150 DPI, which is comfortably sharp on any display and keeps a page to a few hundred kilobytes. Printing renders at 300, the long-standing floor for print, at the cost of a much larger file. There is no slider, because a number of dots per inch is not a decision anybody wants to make.

How to use it

  1. 1 Choose your PDF, or paste one straight from your file manager.
  2. 2 Say what the images are for, and pick JPG or PNG.
  3. 3 Press Convert to images.
  4. 4 Download them one at a time, or take the whole set as a ZIP.

Good to know

  • JPG suits scans and photographs. PNG is lossless and keeps small text and line art crisp, at a larger size.
  • Print resolution is four times the pixels of screen resolution, so expect the files to be much bigger.
  • The text stops being text. If you need it selectable, use the PDF itself, or run the scanner tool to pull the words out.
  • A page with no background of its own is drawn on white rather than left transparent, so it looks like a page instead of a hole.
  • Nothing is uploaded, so a confidential document stays where it is.

Why a PDF page has no resolution until you ask for one

A JPEG knows how big it is. Somewhere in its header sit two numbers, a width and a height in pixels, and every pixel is stored explicitly. A PDF page has neither. What it has is a MediaBox giving its size in points, where a point is exactly 1/72 of an inch by definition, and a content stream of drawing operators: move here, set this font, show this string, fill this path. Nothing in there is a pixel. The page is a set of instructions for producing an image, not an image.

That is why the question "what resolution is this PDF?" has no answer, and why converting one to a picture is a decision rather than a lookup. You are choosing how finely to execute those instructions. At 150 dots per inch an A4 page becomes about 1240 by 1754 pixels; at 300 it becomes 2480 by 3508, four times the pixels and roughly four times the work. The text is drawn from font outlines at whichever size you picked, so it comes out genuinely sharp at both, unlike an upscale of a small render, which cannot invent detail that was never computed.

Rendering itself is done by pdf.js, Mozilla's PDF implementation compiled for the browser, which is the same engine Firefox uses to display PDFs. It runs in a worker thread, which matters more than it sounds: rasterising twenty pages is enough work to freeze a tab, and a frozen tab is indistinguishable from a broken one. The pages come back as canvases, and each is encoded and then explicitly released before the next begins, so a two hundred page document costs one page of memory rather than two hundred.

One detail decides whether the output looks right or looks broken. A PDF page usually declares no background at all, on the reasonable assumption that it will end up on white paper. A canvas starts out transparent, and JPEG has no alpha channel, so transparent pixels are written as black. Convert without painting the canvas white first and every page comes back as white text on a black rectangle. It is a one-line fix and a completely convincing bug, because it looks like a rendering failure rather than a colour-space mistake.

What you lose in the conversion is the thing that made the format worth having. Selectable, searchable, screen-readable text becomes a picture of text, and no amount of resolution brings it back. That is the right trade when something downstream simply will not accept a PDF, and the wrong one otherwise. If the words are what matter, the original file still has them, and OCR can recover them from the picture at some cost in accuracy.

Frequently asked questions

How do I convert a PDF to JPG without uploading it?

Choose the file here. It is rendered inside your browser tab by your own device, and the images come straight back as downloads. You can watch your browser’s Network tab while it works: no request carries the document.

Which is better, JPG or PNG?

JPG for anything photographic, including most scans: it is far smaller and the loss is invisible at these resolutions. PNG when the page is mostly text, diagrams or line art, where lossless encoding keeps thin strokes clean. PNG files of a full page are often several times larger.

What resolution do I get?

Screen or email renders at 150 DPI, printing at 300 DPI. For an A4 page that is roughly 1240 by 1754 pixels, or 2480 by 3508. Both are real renders at that resolution rather than an upscale of a smaller one.

Can I get just one page?

Every page is converted and offered separately, so you can download only the one you want. To work with a subset first, the PDF splitter takes a page list and hands back a smaller document.

Will the text still be selectable?

No, and that is the nature of the job. An image is pixels, so the words become part of the picture. Keep the original PDF if you need the text, or use the document scanner, which reads the words back out with OCR.

Is there a page limit?

No fixed one. Pages are rendered and released one at a time, so memory stays flat rather than growing with the document, but a few hundred pages at print resolution will take a while and produce a large ZIP.
