Capabilities
Diff Anything provides purpose-built comparison modes plus an interactive three-way merge workspace, transactional folder synchronization, connected PDF page and text review, detailed image inspection, APIs, and automated review.
Diff Anything chooses a comparison engine that understands the inputs. Code and text receive language-aware highlighting and moved-block detection, text adds an interactive three-way merge workspace, JSON and other structured formats compare semantic paths, folders can synchronize a reviewed plan with rollback and undo, PDFs connect rendered pages with extracted text, and images offer overlay, swipe, blink, heatmap, and changed-pixel views.
Detect code from filenames, extensions, shebangs, and pasted content, then keep syntax highlighting, moved blocks, wrapping, and compact context visible in desktop and terminal diffs.

Pro folder synchronization previews create, update, and delete counts, then applies the reviewed plan transactionally with rollback and one-click undo.

Read the complete feature guideMove between rendered PDF pages, zoom the originals, switch to extracted text, and follow a selected wording difference to its associated page. Free shows the first 3 page previews; Pro removes that preview cap.
Read the complete feature guideCompare .env keys with values masked, flag malformed or duplicate variables, and compare raw or JSON-shaped HTTP responses with case-insensitive headers and semantic JSON bodies.
Read the complete feature guideExtract comparable text from PDF, DOCX, PPTX, XLSX, and RTF files, or inspect binary format, byte size, dimensions, colour profile, SHA-256 hash, and supported image previews.
Read the complete feature guidePro saves profiles with ignored paths, keyed or unordered arrays, case behavior, numeric tolerances, reviewed states, notes, and live watch.
Read the complete feature guidePro exports self-contained HTML or JSON reports, unified diffs for text, and changed-row CSV for CSV comparisons. It can also run an explicitly confirmed local executable directly—without a shell—on two text sources before comparison.
Read the complete feature guideThe free CLI compares text and JSON with terminal, summary, or JSON output. Pro unlocks every documented mode and YAML/JSON batches that emit summary, JSON, JUnit, or SARIF; both tiers support colour, language, context, opt-in difference exit codes, and Git difftool integration.
Read the complete feature guideWork across in-memory tabs with difference search and filters, reviewed or ignored states, notes, a command palette, cancellable comparisons, diagnostics, density controls, and display scaling. Pro adds saved profiles and local history snapshots.
