Description

New Diffy Pro is the complete file comparison, merge and reading tool for Windows. Compare two files side by side, merge changes in either direction, and read Markdown, HTML, PDF and source code, all in one fast, private app.

Every difference is highlighted the moment you open two files, down to the exact words and characters that changed within each line. A change map shows where every difference sits, so you can jump straight to it. Then decide, change by change, what to keep.

MERGE WITH CONFIDENCE
- Take a change from either side, or Skip it, one block at a time
- Merge All in one click when you trust the other version
- Full undo and redo, so every merge decision can be reversed
- Save straight back to the original file, or use Save As

THE READER: A MARKDOWN VIEWER AND MORE
Diffy Pro includes a built-in Reader for the files you read every day, not just the ones you compare.
- Markdown viewer: open README.md and other Markdown (.md) files as cleanly rendered documents with headings, lists, tables, links and code blocks
- An outline panel lists every heading, so you can jump around long documents instantly
- Read HTML pages rendered, and PDF documents in a native PDF viewer
- Open source code with syntax highlighting, in tabs
- Find and replace, with whole-word and regular-expression search
- Switch between reading and editing in one click, then save

XML-AWARE COMPARISON
Configuration files, VXML menus and XML exports often differ only in attribute order or indentation. XML-aware mode compares the structure, not the layout, so you see the changes that matter and nothing else.

IMAGE COMPARISON
Compare two images side by side, drag a swipe divider across them, cross-fade with onion skin, or highlight every changed pixel with an adjustable threshold. Ideal for UI screenshots, icons and design revisions.

PRECISE CONTROL
- Inline (unified) view of every change in a single pane
- Alignment anchors to line up sections that moved or repeat
- Histogram, Patience and Classic diff algorithms
- Every whitespace mode: trailing and leading, amount, or all whitespace
- Encoding override per file: UTF-8, UTF-16, Windows-1252 and more

SHARE YOUR RESULTS
Export any comparison as a self-contained side-by-side HTML report to send to a colleague or attach to a ticket, or as a Git-ready unified .patch file.

EVERYTHING FROM DIFFY, INCLUDED
- Side-by-side comparison with line-level and word-level highlighting
- Edit in either pane; original encoding and line endings (UTF-8, UTF-16, BOM, CRLF or LF) are kept when you save
- Full Unicode and right-to-left text support, including Urdu and Arabic
- Syntax highlighting for XML, VXML, PHP, JavaScript, TypeScript, C#, Python, SQL, CSS and JSON
- Large files compared in the background; files changed on disk reload automatically
- Drag and drop, recent files, and one-click swap
- Command-line launch with "diffypro" and Git difftool integration
- Light and dark themes, sized consistently at every Windows display scaling

PRIVATE BY DESIGN
Diffy Pro runs entirely on your PC. Your files are never uploaded, and the app collects no telemetry, analytics or personal data. There is no account, no subscription and no licence key: buy once, and it is yours on your Microsoft account.

Diffy Pro is made by Red Icon Technologies.
