PDF to JPG Converter

Turning a PDF into images is the standard fix for a document that will not behave: a form that has to be pasted into an image-only field, a page that must go into a slide deck, a scan that needs annotation in an app that does not read PDF, or a receipt system that only accepts photographs.

Rendering versus extracting

There are two different operations people call "PDF to JPG", and they produce very different results.

Extraction pulls the JPEG images already embedded in the PDF out of the file structure. It is fast, but it only works on scanned documents, it produces one file per embedded image rather than one per page, and it misses all the vector content — text, lines, highlights, stamps and annotations.

Rendering rasterises the finished page exactly as a viewer would draw it. Every element, including selectable text and annotations, appears in the output. This tool renders, which is why a born-digital contract converts just as well as a scanner output.

Choosing a scale

The scale multiplier is applied to PDF's native 72 points-per-inch coordinate space:

• 1× → 595 × 842 pixels for A4. Small files, fine for thumbnails and on-screen review.
• 2× → 1190 × 1684 pixels. The practical default; text stays sharp when zoomed.
• 3× → 1785 × 2526 pixels, roughly 300 DPI equivalent. Use for print or when you need to crop into a region.

Memory scales with the square of the multiplier, so a 3× render uses nine times the pixels of 1×. On a large document that is the difference between seconds and minutes.

Page ranges

The range parser accepts comma-separated pages and hyphenated spans mixed together — 1,3,7-9,15 — and it ignores out-of-range values rather than erroring. This is the fastest way to deal with a long document where you only need a couple of pages.
