Comments on PDF Compare: Diff & Changes for Android
★★★★☆ankit chauhan· Aug 16, 2024
This PDF comparison tool is impressive with its side-by-side swipe feature, making document differences easy to spot. However, it lacks the ability to align PDFs by reference points, which would be useful for different-sized documents with the same content. Additionally, the tool would benefit from a feature to save compared documents showing highlighted changes. Overall, it's effective for basic needs, but a few enhancements could make it indispensable for professionals.
★★★★★Sharath Poojary· Dec 24, 2025
It's a beautiful little app. Small, does its job perfectly. No unnecessary bells & whistles. Lean, clean interface - minimal and very easy to navigate. Only words/chars that are different are highlighted. Whole page is visible at once.
★☆☆☆☆Samuel Dubos· May 12, 2026
App is very poorly coded, do not bother downloading. Unreadable output, false positives and false negatives.
★☆☆☆☆Vicky Sharma· Mar 14, 2026
This app take much time. I upload 2 PDF. This app taking minimum 30 minute but didn't compare
★☆☆☆☆Jim Beam· Sep 3, 2025
All I see is a blurred file. No place for contacting tech support so uninstalled.
