Delta: Compare Docs & Folders

Drop two files and instantly see every difference highlighted side by side. No setup, no configuration - just drag, drop, and compare.

Delta compares PDFs, Word documents, rich text, plain text, and images - showing you exactly what changed between two versions. Compare entire folders too, with a clear tree view of every added, removed, and modified file.
