How to use PDF to JPG

  1. Add the PDF whose pages you want as pictures.
  2. Choose JPG or PNG, then pick a resolution — 72, 108, 144 or 216 dpi.
  3. For JPG, set the quality slider; it starts at 85% and PNG ignores it.
  4. Press Convert and watch the per-page progress.
  5. Download individual pages, or take the whole set as a ZIP named in page order.

How PDF to JPG works

Sometimes a PDF is the wrong container: you need one page as an image for a slide deck, a support ticket or a listing. This tool renders each page exactly as a PDF reader would draw it, then hands you the pictures.

Four resolutions are offered and it is worth knowing what they mean, because a PDF page has no inherent pixel size — only a physical one. The figures are real dots per inch against the page as it would print: 72 dpi gives the smallest files, 108 sits in between, 144 is the default and the setting most things want, and 216 is the sharpest. An A4 page at 144 dpi comes out around 1190 by 1680 pixels; at 216 dpi, around 1790 by 2530. Each result card prints the exact pixel dimensions it produced, so you never have to guess what you got.

There is one cap worth knowing about. No single page is rendered beyond 40 million pixels, because allocating a larger canvas than that is how a browser tab runs out of memory. Ordinary paper sizes never come close — an A4 page at 216 dpi is about 4.5 million pixels — but a large-format sheet can. Roughly A1 is the biggest page that still renders at the full 216 dpi; an A0 poster or an engineering drawing is quietly scaled back instead, landing nearer 160 dpi. Nothing fails and nothing is cropped, and the dimensions on the card are the honest answer to what actually happened.

JPG quality is a separate control from resolution and the two do different jobs. Resolution decides how many pixels describe the page; quality decides how hard each one is compressed. For a page of text, resolution is what keeps the letters legible, so raising the resolution and lowering the quality is usually a better trade than the other way round.

Rendering uses PDF.js, the same engine Firefox uses to display PDFs, running locally in your browser.

Frequently asked questions

Are my files uploaded to a server?

No. This tool runs entirely inside your browser — the file is read from disk by the page and never transmitted. It keeps working even if you disconnect after the page has loaded.

Should I choose JPG or PNG?

JPG gives much smaller files and suits scanned documents and photos, and it is the only format the quality slider applies to — at the default 85% the difference is hard to see, and you can go down to 40% when size matters more. PNG is lossless, so the slider is disabled for it: text edges and flat colour stay exactly as rendered, which is better for diagrams and screenshots, but the files are considerably larger.

Can I download every page at once?

Yes. After converting, use Download all as ZIP to get every page in one archive, named in page order.

How many pages can it handle?

There is no hard limit, but every rendered page stays in memory until you download it, so a long document at a high resolution is the thing to be careful with. Past 60 pages the tool says so before you start; if your device struggles, drop to 108 or 72 dpi, or split the file first and convert it in parts.

Can I use a password-protected PDF?

A PDF that merely declares encryption with an empty owner password usually opens fine. One that genuinely requires a password to be read cannot be processed, and the tool says so instead of failing silently — remove the protection first, then come back.
