PDF to JPG

Turn the pages of a PDF into JPG images. Each page is rendered here in this tab and handed straight back to you, so the PDF never leaves your device. Pick a resolution — screen, good, or print — and download a single page or the whole set as a zip.

How to use it

  1. Choose a PDF — it stays on your device.
  2. Pick JPG and a resolution (150 DPI is a good default; 300 for print-quality).
  3. Convert. Each page becomes an image; download one, or all of them together as a zip.

What JPEG compression does to the edge of a letter

JPEG divides the image into 8 by 8 pixel blocks, describes each as a set of frequency coefficients, and discards the ones the eye is least likely to miss. A sharp black-on-white transition is pure high frequency, which is what gets thrown away first, so the boundary of a glyph picks up faint ringing and a grey halo where the render had a clean edge.

Resolution is the lever. At 96 DPI a 10-point letter stands about 13 pixels tall and its stems sit inside one or two blocks, so the artefacts are the same size as the strokes. At 300 DPI it is around 40 pixels tall, spans several blocks, and the ringing falls below anything a reader notices. If the page is mostly text and JPG is the format required, render high rather than accepting a screen default.

The pages JPEG is genuinely the right codec for

Continuous-tone content is what the format was built for, and on a page of photographs it is not a compromise but the correct answer. An A4 page at 150 DPI is 1240 by 1754 pixels, about 2.2 megapixels; as photographic content that is several megabytes stored losslessly and a few hundred kilobytes as a JPEG, with no difference anyone would pick out.

Scanned documents have a second reason. A scan is usually already held inside the PDF as JPEG data, so rasterising it out to JPG returns it to the codec it was already in rather than introducing a new one. And when the destination imposes a ceiling - an email attachment limit, an upload form, a listing that caps images at 2 MB - JPG is the option that lands underneath without dropping the resolution to compensate.

Questions

Is my PDF uploaded to convert it?

No. Each page is rendered by your browser on your own device, so the PDF and its contents never leave this tab. Most free "PDF to JPG" sites upload your file to a server — which matters for anything private.

What resolution should I choose?

96 DPI is fine for viewing on a screen and makes the smallest files; 150 DPI is a good general default; 300 DPI is print quality and produces large, sharp images. Higher resolution means bigger files and slower rendering.

JPG or PNG — which is better?

JPG makes much smaller files and is ideal for pages with photographs or colour. PNG is lossless and sharper for pages that are mostly text, line art or screenshots, at the cost of a larger file. This tool can do either.

Can I convert just one page?

Every page is converted, then you choose what to save — download a single page from the list, or grab them all as a zip. Nothing is uploaded either way.

How many pages can it handle?

Long PDFs work, but every page is rendered in your browser's memory, so a very large document at 300 DPI can be slow on a phone. Drop the resolution if it struggles.
