The image resolution will vary with the page size. The -scale-to options may be used to set a fixed image size. For the vector outputs, regions of the page that can not be represented natively in the output format (eg translucency in PS) will be rasterized at the resolution specified by the resolution options.

The image dimensions will depend on the PDF page size and the resolution.

The resolution options ( -r, -rx, -ry) set the resolution of the image output formats.

One (and only one) of the output format options ( -png, -jpeg, -tiff, -pdf, -print, -ps, -eps, or -svg) must be used. Not all options are valid with all output formats. If output-file is not used, the output filename will be derived from the PDF-file filename. Using stdout is not valid with image formats unless -singlefile is used. If the output-file is “-”, the output file will be written to stdout. If the PDF-file is “-”, the PDF is read from stdin.

When the output format is a vector format (PDF, PS, EPS, and SVG), output-file is the full filename. When -singlefile is used with the image formats, the file type is appended to output-file. The image formats (PNG, JPEG, and TIFF) generate one file per page with the page number and file type appended to output-file. Pdftocairo reads the PDF file, PDF-file, and writes to output-file. Pdftocairo converts Portable Document Format (PDF) files, using the cairo output device of the poppler PDF library, to any of the following output formats:
