Although there are many free online PDF tools on the Internet, I believe many people will worry about security issues when uploading files to the Internet, so the best way is to use the offline version. If your computer does not have a useful PDF editing software, then the PERFECT PDF 9 EDITOR, which has recently been released for free, is worth a reference. It has quite complete functions, including editing/adding text, images, shapes, tables, and color modification functions. It also supports conversion, such as converting PDF to JPG, splitting PDF, etc. Originally priced at around NT$1,000, it is now completely free.
