Ratings and reviews

Awful. My only tryout was to try to embed a video into a PDF file. Somehow I managed to select a short mp4 video. The result ? When tried the saved pdf to my computer, it only saw a static image of that video (the preview set by android when viewing that video in the folder). So ? lots useless bells and whistles, all without real usage on a real work on a pdf file. I just uninstalled it; no regrets about doing so.

I find UPDF to be an amazing alternative to Adobe with options for both a lifetime license and an annual subscription. There's also an optional AI feature you can purchase that provides fantastic support and time-saving features. Altogether it's a worthwhile investment at an affordable price point. The free version is just as useful as other free PDF readers out there, it's only a matter of preference and specific available features. Highly recommend this app and its desktop counterpart!

I have been using the UPDF PDF tool for more than 6 months, and i have bought lifetime license. I am very happy with the usage, the tools and the interface. I find it easy to grab the content while studying, giving a good feel to study. I am very satisfied with the purchase and the app service. The team ensure that the app is updated frequently to ensure smooth usage. Many thanks to the developing and the maintenance team. One suggestion if possible is to sync the app up to three devices.
