How to convert PDF pages to JPG or PNG images

JPG or PNG?

This choice is not arbitrary — the two formats compress in fundamentally different ways, and picking the wrong one is the most common cause of a disappointing result.

The short version: if the page is mostly text or diagrams, choose PNG. If it is a photograph or a colour scan, choose JPG. Text saved as JPG develops a smeared halo around the letters that no amount of quality adjustment fully removes.

Converting the pages

Each page becomes one image, numbered in document order so the sequence survives when you unzip them.

1. 1Open the PDF to JPG tool — or PDF to PNG if your pages are text or diagrams.
2. 2Choose your file and set the quality or resolution.
3. 3Convert, and download the images as a ZIP if there is more than one page.

Choosing a resolution

Resolution is the setting that actually determines whether the result is usable, and the right value depends entirely on where the image is going.

Converting at a higher resolution than the source cannot add detail that was never captured. It only produces a larger file containing the same information, softly enlarged.

What you lose in the conversion

This is worth being explicit about, because it surprises people after the fact. An image is a picture of a page, not a page.

The text stops being text. Nobody can select it, search it, or copy a line out of it, and screen readers cannot read it aloud — which makes an image-only document genuinely inaccessible to some readers. Links stop working. Any interactive form fields are gone.

File size usually goes up, often substantially. A ten-page text PDF might be 400 KB; the same ten pages as images can easily be several megabytes.

When converting is the wrong answer

A common request is to convert a PDF to images so that it cannot be edited or copied. It does not really achieve that — anyone can run OCR on the images and recover the text — while it does make the document harder for legitimate readers to use.

If your goal is to signal that a document is a draft or confidential, a watermark communicates that directly and keeps the document usable. If the goal is to stop editing, no format conversion provides that; you need the right agreement or a certificate-based signature.

And if you simply need someone to view a document without downloading it, most email clients and messaging apps preview PDFs inline already.

Going the other way

The reverse conversion — images into a PDF — is a separate tool, and the pairing is useful. Convert a page to an image, edit it in an image editor, then convert it back into a PDF.

That round trip is a practical way to make a visual change to a page that no PDF tool offers. It is lossy, and the text layer does not come back, so use it when the page is already a scan and you would lose nothing.
