Sometimes you might want to add additional fonts or language spellchecking support to ONLYOFFICE Docs to enhance the work with the editors. That can be done quite easily.

Bare Bones Instructions

Installing new fonts

By default ONLYOFFICE Docs uses embedded free fonts (true type only in .ttf format) from the operating system where ONLYOFFICE Docs is installed. If you would like to use additional fonts you can do the following:

  1. Install the font by copying it to C:\Windows\Font (to the computer with ONLYOFFICE Docs installed).
  2. Go to the C:\Program Files\ONLYOFFICE\DocumentServer\bin\ folder and run the documentserver-generate-allfonts.bat file as administrator.

    It will scan the system font folder for the installed font, the font will be used by the AllFonts.js script to form the font thumbnails in the editors and add the font metrics to the font_selection.bin file for its further usage.

  3. Restart the ONLYOFFICE DocumentServer Converter and ONLYOFFICE DocumentServer DocService services.
  4. Clear the browser cache and reopen the page.
Adding new language spellchecking support

ONLYOFFICE Docs uses Hunspell compatible format spellchecking service. This allows to easily increase the number of supported languages, which is limited by default. To add a language you will need the following:

  1. Put the language both affix (.aff) and dictionary (.dic) files in the Hunspell format to the C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE Online Editors\SpellCheckerService\SpellChecker\Dictionaries\[lanugage_name] folder.

    For Spanish it will be es_ES folder:
    C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE Online Editors\SpellCheckerService\SpellChecker\Dictionaries\es_ES

Helpful Hints

ONLYOFFICE Docs always has a certain set of fonts with it. When installed it will check the presence of the following font files in the system: arial.ttf, calibri.ttf, cour.ttf, symbol.ttf, times.ttf, wingding.ttf.

When a document is opened for the first time, ONLYOFFICE Docs will check which fonts are present in the document and uploads it from the computer with ONLYOFFICE Docs installation. In case the document contains fonts absent from the ONLYOFFICE Docs computer, it will upload the closest font substitute (the document layout and display might suffer from such substitution).

In case you want to limit the number of fonts uploaded from the system, you can do the following:

  • Remove the unused fonts from the system;
  • limit the number of fonts in documents used (using only most spread fonts: Times New Roman, Verdana, Tahoma, etc.);
  • use compression (dynamic and static) in IIS.
Installing new fonts for older ONLYOFFICE Docs versions

If you are still using versions 3.0 - 3.5 of ONLYOFFICE Docs for Windows we recommend that you upgrade to the latest available version. If you do not have the possibility to upgrade and need to add a new font, the succession of actions should be the following:

  1. Install the font by copying it to C:\Windows\Font (to the computer with ONLYOFFICE Docs installed).
  2. Run the command prompt with administrator rights.
  3. Switch to the C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE DocumentServer\Tools folder (or use the path to the folder with ONLYOFFICE Docs installed):
    cd C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE DocumentServer\Tools
    
  4. Execute the AllFontsGen.exe command with the following parameters:
    AllFontsGen.exe "C:\Windows\Fonts" "C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE DocumentServer\DocService\OfficeWeb\sdk\Common\AllFonts.js" "C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE DocumentServer\DocService\OfficeWeb\sdk\Common\Images" "C:\Program Files (x86)\Ascensio System SIA\ONLYOFFICE DocumentServer\FileConverterService\Bin\font_selection.bin"
    
    It will scan the system font folder for the installed font, the font will be used by the AllFonts.js script to form the font thumbnails in the editors and add the font metrics to the font_selection.bin file for its further usage.
  5. Restart the ONLYOFFICE Converter Service.
  6. Clear the browser cache and reopen the page.

If you are still using the older 2.5 version of ONLYOFFICE Docs for Windows we recommend that you upgrade to the latest available version. If you do not have the possibility to upgrade and need to add a new font, the succession of actions should be the following:

  1. Install the font by copying it to C:\Windows\Font (to the computer with ONLYOFFICE Docs installed).
  2. Open the C:\Program Files\Ascensio System SIA\ONLYOFFICE Online Editors\Tools folder.
  3. Run the GenerateAllFonts.bat file.
  4. Clear the browser cache and reopen the page.
