Description

New Diffy shows you exactly what changed between two files, clearly and quickly, with nothing getting in your way.

Open two files side by side and every difference is highlighted at once. Changed lines are marked, and the exact words and characters that changed within each line are picked out. A change map beside the editor shows where every difference sits in the file, so you can jump to any change with one click or step through them with Next and Previous.

Diffy is built for people who compare files every day: developers reviewing changes, engineers checking configuration and XML files, writers comparing drafts and support teams tracking down what changed between two versions.

COMPARE WITH CONFIDENCE
- Side-by-side view with line-level and word-level highlighting
- A change map that shows the whole file at a glance
- Fast navigation between differences
- Find, word wrap, and syntax highlighting for XML, VXML, PHP, JavaScript, TypeScript, C#, Python, SQL, CSS and JSON

EDIT IN PLACE
Spotted something that needs fixing? Type straight into either pane and save. Diffy keeps your file's original encoding and line endings (UTF-8, UTF-16, with or without BOM, and CRLF or LF), so saving never quietly changes your files. Right-to-left and Unicode text, including Urdu and Arabic, is handled correctly.

BUILT FOR REAL-WORLD FILES
Large files are compared in the background so the window stays responsive. If a file changes on disk, Diffy notices and reloads it. Drag and drop files in, reopen recent comparisons, or swap left and right with one click.

FITS YOUR WORKFLOW
Start Diffy from the command line with "diffy" or set it as your Git difftool to review changes from your repository.

LIGHT AND DARK THEMES
Clean, modern themes in light and dark, sized consistently at every Windows display scaling.

PRIVATE BY DESIGN
Diffy runs entirely on your PC. Your files are never uploaded, and the app collects no telemetry, analytics or personal data.

NEED MORE? MEET DIFFY PRO
Diffy Pro is a separate app that adds everything for professional workflows:
- Merge changes between files with Take, Skip and Merge All, with full undo
- A built-in Reader and Markdown viewer: open README.md and other Markdown (.md) files as cleanly rendered documents with headings, lists, tables, links and code blocks, and jump around them with an outline panel
- Read HTML pages, PDF documents and source code in the same tabbed Reader, with syntax highlighting, find and replace, and a one-click switch between reading and editing
- XML-aware comparison that understands structure, not just text
- Image comparison
- Inline (unified) view
- Alignment anchors for lining up sections that moved
- Patience and Classic diff algorithms, plus every whitespace mode
- Encoding override
- Export comparisons as HTML reports or patch files

Diffy is made by Red Icon Technologies.
