Web Site Optimization: How to Optimize PDF Files for Web Sites - Minimize fonts...
(Page 3 of 4 )
How you use fonts, especially in smaller PDFs, can have a significant impact on file size. Minimize the number of fonts you use in your documents to minimize their impact on file size. Each additional fully embedded font can easily take 40K in file size, which is why most authors create "subsetted" fonts that only include the glyphs actually used.
Fix Fat Forms
Acrobat forms can take up a lot of space in your PDFs. You can use PDF Enhancer from Apago to reduce forms by 50% by removing information present in the file but never actually used. You can also combine a refried PDF with the old form pages to create a hybrid PDF in Acrobat.
Optimizing Existing PDFs
In many cases you won't have access to the original document, just the resulting PDF file. Many PDFs we've seen are not fully optimized for the Web, using conservative settings more appropriate to high-resolution printers. For computer monitors viewing web-based PDFs, you don't need high resolution images and exact reproduction of font faces, you just want to convey your information in an efficient way. Using the techniques outlined below, you can shrink your PDFs, while still maintaining the textual data for search engines, and reasonable quality for print output. Some webmasters offer two versions of their PDFs, once for fast web display, and one for printing.
Once you're done making changes to your PDF document choose File -> Save As and overwrite your existing PDF file. By default, save as removes changes that are appended to PDFs by the Save command, linearizes the file for fast web viewing, and removes unused objects.
