When sending files to a commercial printer, they often request that you convert fonts to outlines first. This is so they can open your files without needing to load the proper fonts onto their system. It not only simplifies their workflow, but streamlines the file transfer process for everyone involved.
There are various ways to create outlines directly in your InDesign files, but I don’t recommend messing with your native files for this. Inevitably you’ll have to make changes to that file, and if you accidentally choose “save” rather than “save as,” your latest editable version could be lost forever. #designersworstnightmare
Instead, I recommend converting fonts to outlines in your PDF files. This is a much safer option, not to mention super simple and fast. Just follow the steps below.
