Although there are many free PDF tools on the Internet, they need to upload the PDF to the server. Therefore, if it is a more important document, I do not recommend it. It is better to use the desktop version. If you don’t have one on your computer yet, Geekersoft PDF Editor Pro 3, which is currently available for free, is highly recommended. It has a Traditional Chinese interface and supports editing, converting, OCR and other functions. It has almost everything you need. The original price is US$39.99, which is about NT$1,200.
