A: Hi,
Thank you so much for your question and feedback — we really appreciate it!
At the moment, it's not possible to edit all text boxes at once (such as changing the font for all at the same time).
However, your suggestion is very valuable to us, and we’ll definitely take it into consideration for future improvements.
In the meantime, you can check out this guide to learn more about batch processing in UPDF: [https://updf.com/updf-windows-user-guide/batch-process-windows/#9]
