formerly WDiff32 Diffoniq · made in Austria since 1995
Diffoniq is the next generation of WDiff32 — a small, native Windows tool that shows two text files, folders or archives side by side, differences marked line by line, merge with a click. No extracting, no account, no cloud. Version 2.0 is in beta now; the public release is coming.
Windows 10/11 · a licence bought today is valid for 2.0 · registered WDiff32 users upgrade free
Diffoniq 2.0 is feature-complete and in a small private beta. Here is the honest state of things.
A closed circle is testing the release candidate. Not a public download yet.
The installer and portable build go public here once the release is code-signed.
A licence purchased now is valid for Diffoniq 2.0 — nothing to re-buy at launch.
Same everyday “what changed?” tool, wider scope.
Open an archive as if it were a directory and compare it against a folder or another archive — without extracting anything first.
Renamed or moved files are matched by content, so a rename shows up as a rename — not as one delete plus one add.
Mark areas, copy them to the other side, paste lines from the clipboard, undo — then save. Merging without leaving the diff.
Whole trees side by side, with sorting, subfolder depth, and ignore rules for time, size, case or singles.
When a text diff isn't the right lens, Ctrl+B checks two files byte by byte.
No account, no telemetry, no cloud. Your files never leave your machine.
Upgrading from WDiff32? Same tool, new name, bigger scope. Registered WDiff32 users get a Diffoniq 2.x licence free — no repurchase. Keep your key; the upgrade path opens with the public release.
One email at the public release. No newsletter, unsubscribe any time.
Double opt-in — you'll get one confirmation mail first.
