When creating a PDF document in Photoshop, what are the best settings to ensure the best quality. PDFs would not be required for printing. Whenever I get a good quality PDF, file size it always too large.
Make sure it is saved in the PDF form. If you are NOT printing the PDFs, then you might be able to get away with setting the Options to a lower DPI. If you plan on putting the PDF online and want to keep the file small, make sure the DPI is within the normal web tolerance (72-92). The higher the DPI you use to maintain good resolution, the bigger the PDF file will be. Try to use a balance between readable PDF file and file size.
Of course, if you plan to use the PDF file as a download file on your web site, then you need to compress the file and provide the url to the compressed file for download. A general notice with link to Adobe's PDF Reader should always be included as a convenience to your viewers.
