Important Tips for How to Write on a PDF Mac

Tip #1: When editing a PDF to add text or simply writing on a PDF Mac using the Markup Mode, remember to save your file once the edits or additions are complete. This way, you can ensure that none of your changes are lost.

Tip #2: Another important tip would be to save a copy of the original file under a different name and then start your editing or write-on-PDF process. In case you need to revert to the original, you can use the Undo button, but the easier way is to keep the original as it is so you can copy-paste content from there or even use it for quick reference purposes.


Now that we've learned how to write on a PDF document on Mac, you can use UPDF for any type of PDF annotation or editing. It's a very handy tool that's also lightweight and simple to use.

Moreover, as new iterations are released, you can gradually start enjoying more advanced features such as file conversion, OCR, and a whole lot more.
