what it does
Everything you need to compare and merge
A focused desktop tool that does one job well: show you exactly what changed, and help you merge it.
Two-way diff & merge
Compare two files side by side with syntax colouring, then copy changes left or right with one click.
Folder compare
Compare whole project folders as a tree and see what’s the same, what differs and what exists on one side only.
Windows, macOS & Linux
One app on every desktop, with native installers for Windows, macOS and Linux.
Word-level highlights
See exactly which words changed inside a line, not just which lines changed.
Change navigation
Jump to the previous or next change, with a running count and an overview ruler of the whole file.
Find in diff
Ctrl+F or Cmd+F searches the comparison, with a match count and highlights.
Encodings & recent pairs
Choose a text encoding for each side or leave it on Auto, and reopen recent comparisons in a click.
Tabs
Keep several comparisons open in tabs, and open a file diff straight from the folder tree.
Light & dark themes
Choose light or dark, or let PlusMerge follow your system setting.
merge
Merge a change in one click
Take a change across with Copy to Left or Copy to Right, copy just the lines you select, or take every change at once. Then save either side, or save it as a new file.
- Copy the current change left or right
- Copy selected lines, or all changes at once
- Save, Save LEFT As… and Save RIGHT As…
folder compare
Folder compare
Compare two folders as a tree. Every file and folder is marked as the same, different, left-only or right-only, with modification dates and a one-line summary of the differences.
- Colour-coded same, diff, left-only and right-only
- Open a file diff straight from the tree
- Copy files across in either direction
- Expand all, collapse all and re-compare
find

Press Ctrl+F (Cmd+F on a Mac) to search the comparison. Matches are counted and highlighted, so you can move from one to the next.
