FAQs

What does the PDFability score for this site mean?: The PDFability score shows how well this website converts into a clean, readable PDF. A higher score means the page produces a clearer layout with fewer distractions when converted using PrintFriendly compared to the default browser print version.
How is this PDFability score calculated?: The score is based on a visual evaluation of the page after conversion. We compare the website's default print output with the optimized version generated by PrintFriendly and measure factors such as layout clarity, visual clutter, readability, and overall PDF quality.
What is being compared to generate this score?: We compare two versions of the same page: the default browser print output and the version generated by the PrintFriendly tool. This comparison helps determine how much the layout, readability, and overall PDF quality improve.
Why does PrintFriendly sometimes create more pages than the native print version?: In some cases PrintFriendly increases the page count in order to improve readability. For example, it may expand images, restore hidden content, or improve spacing and formatting. Even when the page count increases, the resulting PDF can still be cleaner and easier to read.
Can I generate a clean PDF of this website?: Yes. PrintFriendly allows you to convert almost any web page into a clean, ad-free PDF that is easier to read, share, or print. You can use the PrintFriendly extension or online tool to create a PDF of this page.
