What this does

Drop in a PDF and each page is drawn and saved as an image. Choose JPG for photographs and scans or PNG for text and diagrams, set the resolution, and take one page or the whole document. A single page downloads as an image; several arrive as a zip.

The rendering happens in your browser. Nothing is uploaded, which is the difference that matters when the PDF is a statement, a contract or a scan of something with your name on it.

Choosing a resolution

A PDF has no resolution of its own. Its pages are described in points — 72 to the inch — and the text and vector artwork are instructions, not pixels, so they can be drawn at any size. Converting to an image means choosing how many pixels to put in each inch, exactly as you would when printing.

72 dpi renders the page at its nominal size. An A4 page comes out 595 × 842 pixels — fine as a thumbnail, too coarse to read comfortably.
150 dpi is the sensible default: A4 becomes 1240 × 1754, sharp on screen and reasonable to email.
300 dpi is print quality. A4 becomes 2480 × 3508, and files get large quickly.
600 dpi is for archiving or for reading fine print in a scan. Expect several megabytes per page.

Doubling the dpi quadruples the pixels, so the jump from 150 to 300 is four times the data, not twice. Very large pages at very high resolution are capped: browsers refuse to allocate a canvas past roughly 16 million pixels, so the resolution is reduced to fit rather than failing with a blank image, and the tool tells you when that has happened.

JPG or PNG?

JPG for scans and pages that are mostly photographs. It compresses smooth gradients extremely well, at the cost of being lossy — it discards detail it judges you won't miss, which is fine for a photograph and unkind to sharp edges.

PNG for pages that are mostly text, line art, charts or screenshots. It is lossless, so the crisp black edge of a letter stays crisp instead of growing the faint halo that JPEG leaves around high-contrast lines. Files are larger, often several times so, but for text at a readable resolution the quality difference is visible immediately.

If you're unsure: convert one page each way and look at the text at 100%. The artefacts are obvious when you compare directly, and invisible when you don't.

Why the pages are white behind the content

PDF pages are transparent wherever nothing has been drawn — the white you see in a reader is the reader's own background, not part of the file. JPEG has no way to store transparency, so the page is painted onto white before it's drawn. Skip that step and a converted page comes out black, which is the single most common complaint about PDF-to-image converters.

Is it private?

Yes. The PDF is read and drawn by JavaScript inside this page, and the images are made on your own device. Nothing is transmitted, nothing is stored, and there is no server on the other end to receive any of it. Once the page has loaded you can go offline and it will keep converting.

Frequently asked questions

Can I get the text back out?

Not from an image — converting to JPG or PNG turns the text into pixels, which is sometimes exactly the point. If you want editable text, use the PDF to Word tool instead, which extracts the text rather than photographing it.

Why did my scan come out fuzzy?

A scanned PDF is already an image inside a page wrapper, so it has a real resolution of its own. Rendering it above that resolution enlarges the pixels rather than adding detail. If a scan looks soft at 300 dpi, it was probably scanned at 150.

How many pages can it do at once?

There's no fixed limit, but each page is drawn at full size before being encoded, so a long document at 600 dpi asks a lot of your device's memory. The progress bar shows where it has got to. If a big job struggles, convert it in ranges — the Pages box takes 1-50.
