The three things WinMerge users ask for most
These come up constantly in WinMerge forums and Reddit threads. DCP ships them all free.
3-way merge (the #1 request)
WinMerge is 2-way only. When you're resolving a Git merge conflict you need a base/mine/yours view to understand why each side changed. DCP includes this in the free Basic tier — no upgrade required.
Git integration (the #2 request)
WinMerge has no native Git support. DCP uses libgit2 to read branch content directly — compare any two branches, commits, or tags without checkout, stash, or extra commands. Works offline too.
Excel and image diff (the #3 request)
WinMerge treats Excel files as binary blobs. DCP renders them as data and shows you which cells changed. Same for images — you get a visual pixel-level diff. Both free in Basic tier.
Quick start for WinMerge users
The core workflow is identical. These are the only things you need to learn.
Download and unzip
DCP is a single portable exe. No installer, no admin rights. Unzip to any folder — your Desktop, a USB drive, wherever. Then double-click DirectCompare.exe.
Add your folders exactly as you would in WinMerge
Source 1 and Source 2 work the same way. Browse to your folders, click Compare. The results tree shows Different / Only in Source 1 / Only in Source 2 / Identical — same concepts, same workflow.
Double-click any file for the diff viewer
The side-by-side diff viewer works like WinMerge's — prev/next diff navigation, inline character highlighting, sync scroll. Ignore whitespace and CRLF options are in the toolbar.
Set it as your Git mergetool (optional)
Add this to your .gitconfig and you're done:
[mergetool "dcp"]
cmd = "C:/path/to/DirectCompare.exe" -m "$BASE" "$LOCAL" "$REMOTE" "$MERGED"
trustExitCode = true
[merge]
tool = dcp
Now git mergetool opens DCP automatically with the 3-way conflict view. Free in Basic tier.
Try Git branch compare (the big one)
Add a source, change the type to Git, browse to your repo, pick a branch. Add a second Git source with a different branch. Click Compare. You're now diffing branches without a single git checkout.
Already using WinMerge as your Git mergetool?
Switching is a one-line change in your .gitconfig. Replace the WinMerge cmd line with the DCP one above. You gain 3-way ancestor view (base/mine/yours) which WinMerge can't provide — that alone makes merge conflicts significantly easier to resolve correctly.
Frequently asked questions
Is it really free? What's the catch?
The Basic tier is free forever with no time limit. It includes 2-way comparison, 3-way merge, archive compare, Excel/image diff, hex compare, sync preview, exports, and Git mergetool support. Paid tiers unlock Git branch comparison, N-way sources (4+), GitHub, and web/FTP comparison.
Do I need to install anything?
No. DCP is a single portable exe. Unzip it anywhere — Desktop, USB drive, network share — and run it. No installer, no admin rights, no registry changes. To uninstall, delete the folder.
Does it work on Linux?
Yes. DirectCompare supports Linux x86_64. Download the tarball, extract it, and run the binary. The same features work on both platforms.
WinMerge could compare inside archives. Can DCP?
Yes — ZIP, TAR, 7Z, RAR, ISO, and CAB archives are all supported. DCP actually goes further, letting you compare an archive against a live folder or a Git branch.
I use WinMerge's shell integration (right-click compare). Does DCP have that?
Not currently. DCP is focused on the GUI and CLI workflow. If you rely heavily on shell integration, that's worth noting before switching.
Can I try the paid features before buying?
Yes — there's a 30-day full Premium trial that starts automatically on first launch. No sign-up or credit card required.
