When you create a PDF document using Acrobat.com, the resulting PDF file looks different from the original document.
Then, convert the file to PDF again.
The Adobe Acrobat conversion engine has access to all the fonts installed on your system.
Saving to other formats can change page items, such as image placement, line breaks, and page breaks.
If a font in the source document isn't available on the Acrobat.com conversion servers, the font is substituted.
While the Acrobat.com conversion servers have many fonts, Adobe can't provide every font on the market.
