TIFF to PDF ActiveX DLL | Convert TIFF and PDF

Overview

TIFF To PDF ActiveX DLL converts scanned documents and image files in both directions: TIFF to PDF, PDF to TIFF, and PDF pages to BMP, JPEG, PNG, GIF, WMF, EMF or EPS.

It supports single- and multi-page TIFF, page ranges, DPI control, and 24-bit RGB or 1-bit G4 output for compact black-and-white scans. Several images can be combined into one multi-page TIFF or PDF.

The component is standalone and does not require Acrobat, Reader or an image toolkit on the target machine.
