Diff Hub
Compare anything side-by-side — text, PDFs, images, code, and more. Every tool runs entirely in your browser with zero data leaving your device.
Text Diff
Paste any two texts and compare instantly with word and character-level precision. Drag & drop files, share via URL.
PDF Diff
Upload two PDF files and compare their extracted text for additions, removals, and modifications.
JSON Diff
Semantic JSON comparison — order-independent, type-aware, with full key-path reporting for nested objects.
Image Diff
Five modes: side-by-side, fade overlay, slider reveal, pixel highlight, and subtract. Catches single-pixel changes.
YAML Diff
Structural YAML comparison — ignores indentation and quoting. Built for Kubernetes manifests and CI configs.
List Diff
Compare two lists with 5 set operations at once — only-in-A, only-in-B, union, intersection, symmetric difference.
Folder Diff
Compare entire directories locally in your browser. Highlights added, removed, and changed files across trees.
XML Diff
Semantic tree comparison for XML documents — ignores whitespace and attribute ordering.
HTML Diff
Compare HTML code visually with side-by-side rendered previews and structural source comparison.
Word Diff
Compare two Word documents and see exactly what text was added, removed, or changed. Optimized for prose.
