How to Convert PDF to JPG Online
Some upload forms accept only images, and slides or web pages often need a picture rather than a document. Exporting PDF pages as JPG solves that, at the cost of the text layer and every document feature built on it.
Export PDF pages as images
Add your file to the PDF to JPG tool and choose a resolution. Every page becomes its own JPG, and the images are delivered together in a single ZIP archive.
Inside the archive the files are named in page order, so you never have to work out which image belongs to which page. Open at least one image at full size before using them, to confirm that small text is still legible.
Choosing the right DPI
96 DPI is enough for web pages, messaging and quick previews, and produces the smallest files. 150 DPI balances on-screen readability against size and is the right default for most work. 300 DPI is the print setting and keeps small type, footnotes, stamps and signature detail readable.
Resolution affects file size by area, not linearly: a page at 300 DPI holds roughly ten times as many pixels as the same page at 96 DPI. When an upload form enforces a size limit, starting at a lower resolution gives a cleaner result than heavily compressing a large image afterwards.
Exporting a single page
If you only need one page, extract it into its own PDF first with the Page Extract tool, then convert. The archive then contains exactly one image and there is nothing to sort through.
The same approach works for a section. To turn a three-page appendix from a hundred-page report into images, extracting first shortens the processing time and removes the risk of sharing the wrong page.
What you lose in the image
JPG is a picture format. After conversion there is no text layer, no hyperlinks, no form fields, no bookmarks and no document properties; the result cannot be searched and its text cannot be selected. Transparent areas are flattened onto white.
For archiving or formal sharing, keeping the file as a PDF is the better choice. If you only kept the images, JPG to PDF can build a new PDF from them, but the text layer does not come back and OCR is needed to make it searchable again.
Quick checklist
- ✓Try a lower DPI first when an upload form enforces a size limit.
- ✓Use 300 DPI for print and check a page at actual size.
- ✓Remember that transparency is flattened to white in JPG.
- ✓Extract the page you need before converting a long document.

Frequently asked questions
Why is the download a ZIP file?
Each page becomes a separate JPG, so the images are bundled into one archive instead of downloading individually.
Can I export PNG instead?
This tool produces JPG images. Use JPG to PDF if you need to build a new PDF from images.
What is the highest resolution available?
300 DPI, offered as the print-quality option.
