While it covered basic editing and conversion needs, I gradually noticed limitations in areas like advanced OCR, form creation, and workflow efficiency. As my daily PDF tasks became more complex, I started searching for alternatives with more flexibility and modern features.
That search led me to UPDF, which immediately stood out with its cross-platform support and integrated AI tools. You can click the button below to download. In this guide, I'll carry out a detailed comparison of PDF Agile vs UPDF based on real-world testing, practical features, and performance.

Key Features That Make UPDF Stand Out
After looking at the comparison of PDF Agile vs. UPDF features, let me share why I found UPDF to be the better choice for my PDF workflow.
1. UPDF AI: I used UPDF AI to summarize my PDF documents, which helped me quickly understand long reports without reading every page.

Another feature I tried was generating mind maps from PDFs, which helped me visualize document structure and key ideas much faster.

I also used the AI to translate text into 13+ languages in PDFs, making it easy to handle multilingual files and review content in different languages.

2. Scholar Research: I can search a topic and gather multiple papers quickly using the AI platform. Synthesizing them into a structured literature review is fast and highly efficient.

3. Paper Search: The traditional keyword search mode allows me to find relevant papers across multiple academic databases.

DeepThink mode lets me ask research questions and receive answers backed by citations for faster understanding.

4. OCR PDF: UPDF’s OCR feature allowed me to convert scanned PDFs and image-based documents into searchable and editable text. I tested multiple languages, and it accurately recognized characters in all of them.

5. PDF Forms: Creating and editing fillable PDF forms with UPDF was straightforward. I quickly built a survey form and tested form fields, which worked flawlessly. The software also recognized existing form fields in documents, letting me edit properties without starting from scratch, which saved me a lot of time and effort.
