I need a PDF editor. And I think my sister needs one too! Do you need one too? A PDF editor is a program tool to edit a PDF file. We don’t normally need to edit such file. But there are times when we need to edit something like a correction. If there are 100 pages, what’s your best idea of editing the file and saving the file to a new PDF file?
It’s either you copy and paste everything to a document editor like MS Word (if you have a program tool for that), or convert it to a document editor. Then edit the document. And then print the document to PDF.
Or, if you can use a program that would directly let you edit the image and text on it. Then that would be time-saving and effort-saving.
