Convert PDF to JPG

The reason is almost never about the document. It is about somewhere that will not take one. A slide deck that wants an image, a social post, a chat app, a website form, a ticket where someone needs to see the invoice rather than open it. The PDF is fine; it simply cannot go where you are trying to put it.

This conversion gives you one page, and the first one unless you ask for another. That is what almost everyone means — a preview, a cover, a one-page letter — and it avoids the alternative of quietly handing you twelve files you did not ask for.

If you genuinely need every page as a separate image, that is a PDF tool rather than a format conversion, and it is not built yet. Saying so is more useful than pretending.

This works differently from every other conversion here. A PDF stores instructions — a line from here to there, this glyph at that position — which can be drawn at any size without ever becoming blocky. So converting to an image means choosing how large to draw it, and the default is set to be comfortably readable on screen.

The setting is Resolution, in dpi, and it runs from 36 to 600 with 150 as the default. An A4 page at 150 is about 1240 pixels across, at 300 about 2480, and at the 600 ceiling about 4960. You are not enlarging anything; you are redrawing it, so the result is exactly as sharp at 3000 pixels as at 800.

A scanned PDF is not a document at all — it is a photograph of paper in a document wrapper — and it does have a fixed resolution, the one it was scanned at. Drawing it larger stretches the photograph and adds nothing. If your scan looks soft at full size, the detail was never there, and no setting on this page will recover it.

It is worth a moment before you commit to JPG. A page is mostly text, and JPG compression is built for photographs — it smears the boundary between black letters and white paper, which shows as a faint fuzz around every word. On a page of prose the difference between JPG and PNG is obvious at a glance. Choose JPG when the page is dominated by a photograph, and PNG when it is dominated by words.

And the text itself: once the page is an image, the words are pixels. They cannot be searched, selected or copied. If somebody needs the text rather than the look of the page, open the PDF in any reader and copy it out — it is still text in there right up until this conversion turns it into a picture.

One page becomes one image, and the page to convert is a setting rather than an assumption. That matters more than it sounds: the page people want out of a contract or a report is rarely page one, and a converter that silently gives you the cover has answered a question nobody asked.

If you want several pages as images, convert them one at a time — or extract the pages you need into a shorter PDF first, which is a separate tool on this site and usually the faster route for anything beyond two or three.

JPG compression was designed for photographs, and a page of text is the opposite: hard black edges on flat white. Compressing those leaves a faint smear around every letter, which at reading size looks like the scan was slightly out of focus.

PNG handles the same page cleanly and, because flat white compresses extremely well, often produces a smaller file than JPG does on this particular content. If the page is mostly a photograph, JPG wins comfortably — which is why both conversions exist rather than one.
