Hi,
Thanks for your inquiry. This is Amber from E-iceblue support team.
Do you want to convert multiply images to a Pdf file or convert a multi-page Pdf file to images?
For case one, you could draw the images on Pdf pages one by one. The result Pdf will not be only one page.
For case two, our Spire.PDF converts one Pdf page to one image file. The result images won’t be just one page.
If you still have the issue, please describe your issue in detail and offer us your input file(if any) as well as the complete code you were using. You could upload them here or send us(
support@e-iceblue.com) via email.
Best wishes,
Amber
