Easy to handle and quite a complete product Review collected by and hosted on G2.com.

1. The AI is not sufficiently up to date, I am not sure that the latest language models like GPT 5.5 are being used. 2. There are still bugs in the use of text modification (breaks in the blocks that prevent reworking the texts after a translation, for example). 3. Account access is not automatic at the start of the product, if you want to translate you have to log in manually. 4. Connection is impossible from mainland China, requiring the use of a VPN. If an attempt to connect is made, the product blocks. 5. I purchased a year of AI service at the beginning of 2025 which was not taken into account, I had to purchase another year of service at the end of 2025. Review collected by and hosted on G2.com.

I really like how clean and easy the interface is—it doesn’t feel overwhelming like some other PDF editors. Even if you’re new to editing PDFs, it’s pretty quick to figure out where everything is and how to get started.

It also works across all my devices. I can use it on Windows, Mac, my iPhone, and even Android, which means I can start editing on my laptop and then pick it up later on my phone without any hassle. That flexibility is super handy.

The AI feature is genuinely useful, too. I was skeptical at first, but the AI assistant can summarize long documents, translate text, and explain more complex sections. It saves me a lot of time when I’m studying or dealing with big reports for work.

Editing PDFs feels a lot like using Word. I can change text, move images, fix typos, and tweak fonts without needing the original file, which I really appreciate since I don’t always have the source document.

I have been using the AI assistant for 2 years as a master student. It's helpful for my literature review every day. And there is student price for it. I would definitely recommend it to peers and heavy-profile readers. Review collected by and hosted on G2.com.

I’d love to see built-in cloud storage integration, such as the ability to connect directly to Google Drive or Dropbox.

The OCR could also be improved for handwritten notes or low-quality scans—right now it isn’t always accurate.

Real-time collaboration (similar to Google Docs) would be amazing, especially for team projects. Review collected by and hosted on G2.com.

I like that UPDF gives me the option to edit any PDF in the best possible way. Furthermore, it is much better, more stable, and faster than Foxit. The initial setup was also smooth and very easy, even for someone like me who already has good knowledge. Review collected by and hosted on G2.com.

As I also use UPDF on the iPad, it could be more adaptive for writing like a digital notebook with the pen, I really miss that. Today I use UPDF for everything related to PDF, but when I go to the iPad I still have to subscribe to another platform, because there the handwriting with the pen is much better, so when going to the iPad, it should be more like a notebook, allowing writing with the pen in a more subtle way, and of course being able to edit the same PDF, and having the folders more separated, in a more beautiful way to store in the cloud.

The features for creating, editing, and annotating PDFs are intuitive, and the UI helps with user convenience. The AI assistants feature is attractive as it is not found in other PDF tools, and it is convenient to create text-readable files through the OCA feature when generating PDF files. Converting PDFs to Excel or Word is also useful, and it's great for quickly reading and summarizing large PDF files or searching for information, and even organizing them into mind maps. The UI is easy to understand and intuitive, considering user convenience, which is great. The installation process was very simple and the setup was easy. Review collected by and hosted on G2.com.

When working with large files, approximately in the hundreds of MB range, the program often shuts down due to high memory usage. Review collected by and hosted on G2.com.

I like the ease of use with UPDF and its intuitive nature. I appreciate the fact that UPDF can convert files into another format, like Word or PowerPoint, making it easier to incorporate with my other work. Additionally, UPDF offers everything that Adobe does but for a fraction of the price, and it provides a lifetime license. I'm also able to highlight or manipulate a PDF document, which I used to regard as just a photo rather than a workable document. Review collected by and hosted on G2.com.

I'm not quite sure I understand all the features. And it would be helpful if when you click on a particular feature, some explanatory information was available on exactly how to do this. Review collected by and hosted on G2.com.

I love the aesthetics of UPDF; they are just appealing to the eye. The cloud service included for me is a great way to keep my already congested iCloud from becoming more cluttered. I also paid for a lifetime license at a reduced rate, so I can't complain. The initial setup of UPDF was very straightforward. Review collected by and hosted on G2.com.

I find the documentation lacking since there's literally nothing on how to actually use the software, and what's there is so outdated that it's obsolete. The lack of templates is disappointing; users are led to believe there's a fleet to choose from, but there are maybe 10, if that. The AI feature was hands down the absolute worst iteration I've seen, to the point of being laughably unusable. I also noticed there's no direct integration possible, which limits its functionality with other tools I use. Review collected by and hosted on G2.com.

I use UPDF for day-to-day PDF viewing and editing. I appreciate that it solves the issue of having to pay for a subscription to Adobe by offering the same features for a single price. The price of UPDF compared to its competitors is what I like most. Additionally, the initial setup was very easy, with a one-click install. Review collected by and hosted on G2.com.

The CAC/PIV signing ability is missing or does not function properly. If you could integrate the ability to sign with CAC/PIV, it would enable me to completely remove Adobe from my computer and use UPDF as my sole PDF viewer/editor. Review collected by and hosted on G2.com.

I use UPDF primarily for personal use, like filling out forms and signing documents. It's affordable with a monthly subscription, which I can cancel anytime. I like that my basic needs are met, such as creating a text box to fill out the form and sign documents using my own signature. The initial setup was easy and straightforward. Review collected by and hosted on G2.com.

Make the text box moveable using the arrow keys, please. And please add alignment of any of the object boxes, like the text and signature box. I just want to make sure I have the option to align things. For monthly payments, please make it available on web/desktop, please. I don't understand why you are only offering it on mobile. Moreover, I wish there's an AI option to create input fields on PDFs that doesn't have it. Review collected by and hosted on G2.com.

What I enjoy about UPDF compared to Adobe Acrobat Pro is that the AI features and various app tools don't get in the way. There are no pop-up asking me if I want to summarize the document, or tips that get in the way if reading the PDF. Everything is available for use, but tucked away as to not be in the way.

There's nothing I dislike about UPDF. It opens PDF files, has a rich amount of features, and doesn't get in my way when opening and reading documents. Review collected by and hosted on G2.com.

The best thing about this app is that it offers a huge range of features—OCR, PDF editing, and so on. Review collected by and hosted on G2.com.

That there is no OCR for Slovenian. It used to exist, but now it's gone. Review collected by and hosted on G2.com.
