Frequently Asked Questions

When you purchase UPDF, you can use it on up to 4 devices: 2 desktops (either 1 Windows and 1 Mac, 2 Windows, or 2 Macs) and 2 mobile devices (1 iOS and 1 Android, 2 iOS, or 2 Android). If you opt for the license with AI Assistant, you can access the AI features online and on up to 4 devices: 2 desktops (1 Windows and 1 Mac, 2 Windows, or 2 Macs), 2 mobile devices (1 iOS and 1 Android, 2 iOS, or 2 Android). You’re also allowed to reinstall on a new device when replacing an old one.
For a better understanding of the differences between a yearly plan and a lifetime plan, the following aspects should be kept in mind:

1. Yearly plan means that the selected package will auto-renew automatically annually. However, the lifetime plan is a one-time fee and can get lifetime updates.
2. Users who subscribe to the yearly plan will be entitled to receive unlimited free updates and upgrades throughout the term of their annual payment. In contrast, users who choose the lifetime plan will benefit from lifetime access to all future updates and upgrades.
3. Yearly plan can get 110GB (Pro: 10GB + AI: 100GB) of cloud storage and the lifetime plan can get 102GB (Pro: 2GB + AI: 100GB) of cloud storage.
1. The free version automatically adds a trial watermark when saving the document.
2. PDF conversion is limited to up to 2 times a day.
3. Batch processing can only handle two files in the free version.
4. The trial version limits OCR to 5 uses.
5. Only one template can be added on the watermark, header and footer, and background separately.
6. The UPDF Cloud trial version includes 1GB of storage space with a limit of 10MB for a single file. (The premium account has 10GB storage space with 2GB max per file for uploading.)
If you want to test AI Assistant, there are some specific limitations while using its trial version, which is mentioned as follows:

1. You can only upload and analyse up to 5 PDFs and a maximum of 100 pages/PDF.
2. The file size is limited to 100MB per PDF file.
3. Free questions are limited to a maximum of 100 times.
4. With the online AI, users can chat with multiple PDFs by creating collections. However, free user can upload up to 5 PDFs in one collection.
In case you only buy the AI Assistant, you will still be a free user of UPDF, limiting your access to tools like editing, annotating, and converting PDFs. However, you can try and use all the features of UPDF but with certain limitations such as trial watermarks being added.
If you only purchase UPDF without the AI Assistant, you can only analyze 5 PDFs with AI or ask 100 questions for testing. Should you require additional tokens, you will need to purchase the AI Assistant additionaly.
If you have any questions, we recommend you contact the customer support team by emailing [email protected]. Moreover, you can visit the User Guide and FAQs page to learn more about UPDF and AI Assistant.
AI Assistant is available on Windows, Mac, iOS, Android and Web. When you purchased AI Assistant for your UPDF account, you gain access to it on all five platforms. You can access the AI feature on Windows, Mac, iOS, and Android devices by downloading the UPDF program. Alternatively, you can use AI features directly on your browser by visiting ai.updf.com.
