Is it possible to export a pdf page to a JPG or other format?
No, it’s not possible to export to JPG.
Can you please add this feature request ?
Sumatra is more of a reader than editor. At the moment I have no plans to add that.
@hesaho Ensure “Show pages continuously” is OFF
Right click the page
Select All AND THEN Copy Selection
Start Run Mspaint PASTE and save as JPG
Install PDFCreator (IMO v1.73 is better than newer versions) make sure to disable optional components. It will install a printer driver able to print to JPG, PNG, PDF, etc. So just select page, and print it to PDFcreator printer.
