If you are unsure on how to select and remove fonts when altering the file properties, see the next question.) How to Remove Embedding Fonts When Saving file to a PDF! Open your PDF file and click Edit — PDF file Options — Fonts tab. Check 'Embedded fonts disabled' (or 'Do not embed fonts' as of macOS 10.11 Yosemite, but we recommend to check 'Don't embed fonts'). Press Command+Enter to save that as default — no error dialog box. In order to revert to the previous behavior, you can choose your Font — or use Command+Click in order to copy/paste the font text, and then uncheck that Font in the Options' dialog box. Fonts not included in the file If you find a font that is not already included in the file to be embedded in a PDF you've uploaded to the Web, please send us the link to this page, and we will attempt to add it, but please be aware that as many files are already on file sharing sites, we cannot make a determination on the authenticity of each piece of information contained in them. It is however possible for us to determine if you have uploaded a valid file, as all the information contained in this document can be found in the file. How is embedding a font useful? It allows you to share a PDF file online (see PDF sharing options section below) or in a professional journal without the need for a special application such as Adobe InDesign or Word. How to Embed Fonts in PDFs in general Please follow the above steps but, for many fonts (in PDF file sizes) it might be better to include the fonts in the document in a separate file (in the following sections are suggested files): Fonts you want to embed will be stored in a “Font Files” folder within this folder (by default it is just “Font File,” but you can use the “Open...” menu to choose another name, “font file” to open the file in Preview, “font file” again for saving the file as a PDF). When you are done using the font you want, you can remove it from the font files folder.
