My university requires us to scan homework to PDF and send it via the website, and I have a problem using paper because my writing is messy. I saw some students using an iPad or a Chromebook to write directly on a PDF ,using the pen with the device, and it looks so clean and if there is a mistake they can always press Ctrl+Z. I'm using an Acer Laptop with Windows 10 Home without a touch screen, Is there a software that lets me write PDF files with a mouse that is close a real life pen effect ( I searched online for softwares and there is a lot of options and I can't test them all), other than getting a new device?
I'm not an expert on this and I'm not affiliated with the software but I would recommend you use Adobe Acrobat to write on the PDF directly on the digital document. The Adobe reader is free to download use and can be used to annotate like highlighting, putting x marks or checkmarks, adding a line, adding text, a circle or a dot, and of course, signing as if it was a handwritten signature. But if you want to do more freehand writing and free-form drawings around your document, you need to purchase the pro version. The Pencil tool creates free-form drawings, and the Pencil Eraser tool removes the pencil markups. Here are more details from their support page: https://helpx.adobe.com/acrobat/using/commenting-pdfs.html
All current versions of PDF-XChange Editor will allow you to do this.
Simply go to the
Comment menu and select the
Pencil tool. There is also an
Eraser tool for your convenience.
You can customize the toolbars to place those tools on any toolbar of your choosing, or even a brand new custom toolbar.
I have personally used PDF-XChange Editor, and I find the quality of the product to be very high.
