Failed to decode downloaded font

Question

This is an error I am getting in Chrome and unfortunately searching for it hasn t given me much results  The font itself is appearing correctly  However I still get this error warning  More specifically  this is the full warning       Failed to decode downloaded font    http   localhost 8000 app fonts Lato     My CSS are these    font-face       font-family  Lato       src  url     fonts Lato        html  body       font-family  Lato       I just do not understand  The font is applied correctly  but the warning is always there  Trying to use Sans-Serif makes the font revert to the normal browser font  so that may be it  but I am not sure  and even after searching I have found nothing  Thanks   EDIT  There are various font files  all from the same family  I am trying to load them all  The font files are  ttf  I am loading them from a local folder  and there are various font-files  like Lato-Black ttf  Lato-Bold ttf  Lato-Italic ttf etc

For me  the mistake was forgetting to put FTP into binary mode before uploading the font files   Edit  You can test for this by uploading other types of binary data like images  If they also fail to display  then this may be your issue

My case looked similar but the font was corrupted  and so impossible to decode   It was caused by configuration in maven  Adding nonFilteredFileExtension for font extensions within maven-resources-plugin helped me    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-resources-plugin lt  artifactId gt       lt configuration gt           lt nonFilteredFileExtensions gt               lt nonFilteredFileExtension gt ttf lt  nonFilteredFileExtension gt               lt nonFilteredFileExtension gt otf lt  nonFilteredFileExtension gt               lt nonFilteredFileExtension gt woff lt  nonFilteredFileExtension gt               lt nonFilteredFileExtension gt woff2 lt  nonFilteredFileExtension gt               lt nonFilteredFileExtension gt eot lt  nonFilteredFileExtension gt           lt  nonFilteredFileExtensions gt       lt  configuration gt   lt  plugin gt

In my case when downloading a template the font files were just empty files  Probably an issue with the download  Chrome gave this generic error about it  I thought at first the solution of changing from woff to font-woff solved it  but it only made Chrome ignore the fonts  My solution was finding the fonts one by one and downloading replacing them

I also had same problem but i have solved by adding  Content-Type     application x-font-ttf  in response header for all  ttf files

If it is on the server  not in localhost   then try to upload the fonts manually  because sometimes the FTP client  for example  FileZilla  corrupts the files and it can cause the problem  For me  I uploaded manually using Cpanel interface

If you are using express you need to allow serving of static content by adding something like   var server   express    server use express static    public        where public is the app root folder  with the fonts contained therein  at any level  i e  public fonts or public dist fonts       If you are using connect  google for a similar configuration

For me  this error was occuring when I referenced a google font using https  When I switched to http  the error went away   and yes  I tried it multiple times to confirm that was the cause   So I changed    import url https   fonts googleapis com css family Roboto 300 400 100 500 900     To    import url http   fonts googleapis com css family Roboto 300 400 100 500 900

I was having the same issue with font awesome v4 4 and I fixed it by removing the woff2 format  I was getting a warning in Chrome only    font-face     font-family   FontAwesome     src  url     fonts fontawesome-webfont eot v 4 4 0      src  url     fonts fontawesome-webfont eot  iefix amp v 4 4 0   format  embedded-opentype    url     fonts fontawesome-webfont woff v 4 4 0   format  woff    url     fonts fontawesome-webfont ttf v 4 4 0   format  truetype    url     fonts fontawesome-webfont svg v 4 4 0 fontawesomeregular   format  svg      font-weight  normal    font-style  normal

In the css rule you have to add the extension of the file  This example with the deepest support possible    font-face     font-family   MyWebFont     src  url  webfont eot       IE9 Compat Modes      src  url  webfont eot  iefix   format  embedded-opentype       IE6-IE8           url  webfont woff2   format  woff2       Super Modern Browsers           url  webfont woff   format  woff       Pretty Modern Browsers           url  webfont ttf    format  truetype       Safari  Android  iOS           url  webfont svg svgFontName   format  svg       Legacy iOS        EDIT    Failed to decode downloaded font  means the font is corrupt  or is incomplete  missing metrics  necessary tables  naming records  a million possible things    Sometimes this problem is caused by the font itself  Google font provides the correct font you need but if font face is necessary i use Transfonter to generate all font format   Sometimes is the FTP client that corrupt the file  not in this case because is on local pc   Be sure to transfer file in binary and not in ASCII

In my case  this was caused by creating a SVN patch file that encompassed the addition of the font files  Like so    Add font files from local file system to subversioned trunk Trunk works as expected Create SVN patch of trunk changes  to include addition of font files Apply patch to another branch Font files are added to subversioned branch  and can be committed   but are corrupted  yielding error in OP    The solution was to upload the font files directly into the branch from my local file system  I assume this happened because SVN patch files must convert everything to ASCII format  and don t necessarily retain binary for font files  But that s only a guess

Make sure your server is sending the font files with the right mime type   I recently have the same problem using nginx because some font mime types are missing from its vanilla  etc nginx mime types file   I fixed the issue adding the missing mime types in the location where I needed them like this   location  app fonts        Fonts dir   alias  var www app fonts       Include vanilla types   include mime types      Missing mime types   types   font truetype ttf     types   application font-woff woff     types   application font-woff2 woff2       You can also check this out for extending the mime types in nginx  extending default nginx mime types file

Sometimes this problem happens when you upload download the fonts using the wrong FTP method   Fonts must be FTP-ed using binary method  not ASCII   Depending on your mood  it may feel counterintuitive  lol   If you ftp the font files using ASCII method  you can get this error message   If you ftp your files with an  auto  method  and you get this error message  try ftp forcing the binary method

In my case -- using React with Gatsby -- the issue was solved with double-checking all of my paths   I was using React Gatsby with Sass and the Gatsby source files were looking for the fonts in a different place than the compiled files   Once I duplicated the files into each path this problem was gone
