    One of the things that I have noticed the most is that it saves a lot of time when working with documents of different formats that need to be converted to PDF. Scanning documents is also one of the best features of this app. Being able to have the history of modifications, and changes in the documents is very important for any sector, as well as the signing of documents online. The issue of authentication every time you need to use it can sometimes cause inconvenience, but then you forget when you have a robust and comfortable tool to work with. I do not recommend this application if the company has different versions of operating systems. It is not the most recommended application.

    Pros
    Kdan Mobile Software Ltd.
    • First of all, I really like how the synchronization feature works - it's very convenient to switch between devices (one more advantage of the app - it has a nice mobile version) and still have all the documents right there in the, synced and ready to go.
    • Besides, the software provides users not only with annotating features that allow you to highlight and add information, but also allows you to sign documents on the go, without having a necessity to print them, so you don't actually even need an e-signature app.
    • Another thing I like is how easy it is to use right away, at least the majority of the tools, anyway.

    Cons
    Kdan Mobile Software Ltd.
    • Well, there are a few downsides, I guess, but not very significant ones. Firstly, because of the large amount of features the interface doesn't look as simple as I wish it did - it's a bit overcrowded.
    • Secondly, because of the first issue that I've mentioned, adjusting to the software takes longer than it could if the interface was simpler. For me personally, it wasn't a big issue, but for those who don't get accustomed to unfamiliar tools easily it could be a problem.
    • Finally, there is one more problem that is actually not significant at all, but when you want to load a document from the Cloud or open the task manager, the app will open a new window for those tools every time - it can be a bit confusing because of so many windows being opened at once.

    We have also tried Expert PDF Reader. There were no converting, signing, faxing or features. In general, it was far less useful.

One click switches to the Editor to fill, annotate, or redact the same document.Screenshot of Users draw a freehand signature, type one, or upload an image — then insert it into any PDF in one click. Checking "Save this signature for next time" eliminates re-entry on future documents, speeding up e-signing for legal, HR, and contract workflows.Screenshot of Users on Windows or macOS can install the full native desktop experience — all 70 PDF tools, offline-capable and synced with PDF9 Drive.
