How to convert PDF to JPG
- Add the PDF you want to convert by dragging it onto the upload area, or click to browse.
- Choose the image format — JPG for small files, PNG for lossless quality — and the resolution: 72 DPI for screen use, 150 for documents, 300 for print.
- Convert all pages or enter a range like 1-3, 5, then click "Convert to images".
- Download the result — a single image if you converted one page, otherwise a ZIP archive with one image per page.
Rasterize pages without handing over the document
Turning a PDF into images usually means the document is headed somewhere visual — a presentation, a messaging app, an upload form that only accepts pictures. Invoices, certificates, and official letters often take this route. With a typical online converter, the whole document is uploaded first and the images come back from a server you know nothing about. CoolPDF renders the pages right in your browser tab, using the same class of PDF engine that powers desktop readers. The file never crosses the network: it is read from your disk, rasterized by your device, and saved back to it. There is nothing to intercept, log, or leak — which also means the tool keeps working on a plane, in a factory, or anywhere else without a connection.
Frequently asked questions
Which DPI should I choose?
72 DPI matches the PDF’s screen size and is fine for web use. 150 DPI is a good middle ground for documents. 300 DPI is print quality — sharp, but the images get large and rendering takes longer.
Why do I get a ZIP file?
Each PDF page becomes its own image. When more than one page is converted, all images are packed into a single ZIP archive so you get one tidy download.
Does converting to JPG lose quality?
JPG uses light compression (92% quality), which is visually indistinguishable from the original for documents and photos. Choose PNG if you need pixel-perfect, lossless output.
