How to use it
- Pick a resolution and, if you like, a page range.
- Drop in the PDF.
- Download each page image, or all of them as a zip.
Why PNG suits most PDFs
Most PDFs are made of text, lines and flat areas of colour. PNG stores those perfectly and compactly, with no fuzz around letters. JPG is designed for photos and tends to leave faint smudges near sharp edges. If your PDF is a brochure full of photographs, PDF to JPG will give smaller files; for nearly everything else, PNG is the better choice.
A few practical uses
- Putting a single slide or chart into a report or chat message.
- Making a thumbnail preview of a document's first page (use page
1at 72 DPI). - Posting a page of a newsletter or menu on social media, which will not accept PDFs.
- Annotating a page in an image editor.
Backgrounds
PDF pages are rendered on white, which is how they appear in any reader. The PNG will not have a transparent background even if the PDF page technically does.
