If you’re creating a web page using Flash, it’s easy. Consult your Flash manual.
If you’re using Acrobat, make sure the font embedding settings are turned on. Consult your Acrobat manual.
For anything else there are limitations:
If you want to use one of our fonts as your main, text font you’re pretty much out of luck unless you explore a font embedding tool such as WEFT but I don’t recommend it. To use our fonts as headings or titles, use image creation software such as The Gimp, Photoshop, Paint Shop Pro, Pixia etc. Save the images as GIF files and place them on your web page. There’s a lot more to it than can be explained here but there are countless books available on web page design.
