Sometimes we are asked by clients what fonts we used in their project. Here is a tip that allows you to find that out if you have a PDF.
Open the PDF, go to File > Properties and click on the Fonts tab, which displays the names of the fonts that were used. If there is more than one font, you won’t be able to tell exactly where in the document it was used unless you are already familiar with the look of the font(s), but this can still be a helpful resource. Please note that this works only for text that has not been rasterized (converted into an image) prior to creating the PDF.
