签署PDF文件 - 无需打印，在线签印

不能用，全是强迫广告

基本是骗钱的，只能签pdf还没有使用介绍，做得很粗糙，根本没用

Don’t bother. Down loaded app to use to sign a PDF. No where to load the PDF into the app, adverts are annoying and in the way/tricks you to down load other apps. Managed to sign my signature but no further functions to load into a PDF document, transfer it or even save it. Waste of time.

Seems a good app to add text or a signature to pdf documents. Takes less memory than Acrobat app but does similar changes. Can save signatures and edited documents in app plus e-mail them. It is a free app so it is understandable that there are adverts (full screen so they are a bit obtrusive but ads can be closed). I have not been able to dot a lower case i yet.
