Convert a PDF to JPG
Turn the pages of your PDF into JPG images — a single image, or a ZIP archive when the document runs to several pages. Resolution and quality are both adjustable.
When to pick JPG over PNG
JPG compresses with loss: it discards part of the visual information to bring the file size down. On a page holding photographs, gradients or illustrations the loss is invisible and the saving is dramatic — often five to ten times lighter than the equivalent PNG.
On plain text or a flat-colour diagram, though, JPG compression leaves a grey halo around letters and lines. For that kind of content PNG gives a noticeably cleaner result.
Choosing the right resolution
Resolution is set in DPI, or dots per inch. 72 DPI is enough for a screen or a thumbnail. 150 DPI, the default, is the sweet spot for comfortable reading or dropping into a slide deck. 300 DPI is the print threshold: beyond it the file grows without any visible gain.
The quality slider controls compression instead. 85% is a safe setting; below 70% artefacts start to show around text.
Frequently asked questions
How do I get every page of a PDF as JPG?
Choose ZIP as the output format: Morphix renders one image per page and returns them all in a single archive. You can also give a page range such as 1-3 to convert part of the document only.
Which resolution should I use for printing?
300 DPI. That is the point beyond which the eye stops seeing any improvement on paper, while the file size keeps climbing.
Does JPG keep transparency from the PDF?
No — the JPG format has no transparency channel, so transparent areas turn white. If your PDF holds a logo or a cut-out you need to keep, convert to PNG or WEBP instead.
