What is Diff Guru?
DiffGuru is the developer’s go-to for text, code and file comparison. Whether you’re reviewing code, checking document revisions, or merging updates, DiffGuru makes the process fast and intuitive.
Instantly paste or upload two texts/files and see differences clearly: additions, deletions, moved lines, with line numbers and color-coding.
Merge changes between versions easily with built-in merge options.
No registration needed, no personal data collected - your input is processed in real time and not stored, making it a secure and private choice.
Designed for both casual users and professionals: lightning-fast interface, minimal clutter, and full support for developers working with configs, code snippets, documentation or content.
Loved by teams and individuals alike: helps streamline code reviews, document drafts and version comparisons, saving hours of manual checking.
DiffGuru has now expanded beyond text and code with powerful new comparison tools designed for real-world file formats:
Image Compare – Instantly compare two images to detect visual differences, pixel-level changes, and layout shifts. Ideal for designers, QA teams, and UI audits.
PDF Compare – Upload and compare two PDF files to highlight content changes across pages. Perfect for contracts, reports, invoices, and documentation reviews.
JSON Diff – Compare two JSON objects side by side with structured highlighting. Great for API debugging, configuration validation, and backend development workflows.
Excel Compare (CSV, XLS, XLSX) – Compare spreadsheets cell-by-cell to quickly identify data mismatches, updates, and missing values. Useful for analysts, finance teams, and data engineers.
All these tools follow the same core principles DiffGuru is loved for - instant processing, no signup, privacy-first design, and a fast, clutter-free user experience. Whether you’re working with code, documents, images, or structured data, DiffGuru now serves as a complete all-in-one comparison platform.
