If you do not make any changes you will NOT get this dialog, and NO changes will be made to your original file. If you proceed without resolving the missing fonts, a default font will be substituted in. I have a drawing (Drawing A) that contains a PDF (using PDF attach) with text over the PDF. Last updated on If you see a Missing Fonts message upon opening a file in one of your desktop applications, this means that the file uses fonts that you don’t currently have on your computer. If you do make changes, you will get this dialog box while closing the file or quitting Illustrator. Either they dont show at all (like Helvetica Neue font). I'm attaching the screenshots, of the error msg your getting but will not make any changes to you PDF file if you quit (Assuming you did not edit anything in Illustrator) The fonts will remain the same when you open it in Adobe Reader, since the font files are normally embedded in the PDF itself. Any other extension also use the same procedure. Once you get the font files downloaded, extract the. Search with the font names the error is showing you. To me, both seem like proprietary fonts, so once you get them downloaded, read on. If they are free fonts, you will get them on DaFont. And here's another one to a Wikipedia article about the usage share of the different operating systems. Here's a link to a site with some of the fonts that come pre-installed with different operating systems. This will also take some load off you server even though serving fonts isn't such a big deal.

Keep in mind this is far from ideal in most cases but would allow you to avoid licensing costs and reduce the time it takes for your website to load (since it will not be downloading fonts). Your font stack could be something like font-family: "Helvetica Neue", Helvetica, Arial, sans-serif and you'd be covering the most common devices and operating systems (except for Android which I think doesn't come with any of those two font families).

Unfortunately Arial Narrow isn't included in iOS but, since both Helvetica and Helvetica Neue come pre-installed in all Apple devices, you wouldn't have to worry too much about it. It comes pre-installed in (almost?) every Windows version and also Apple devices. Around the same time that Adobe was developing PostScript, Monotype won the contract to provide fonts for IBMs first big laser-xerographic printers. Unless you need something that looks almost exactly like Helvetica, Arial might be an option you should consider.

Everyone's been giving you names of fonts that look similar to Helvetica (some more than others) but depending on what kind of project it is that you're working on you might not need any of those.
